Mitsubishi Electric Substation Division (SSD) has the capability to specifically design, manufacture and install Gas Insulated Switchgear (GIS), leveraging its relatively compact and completely encapsulated metal structure, to provide significant advantages for SSD’s power utility customers. Compared to air insulted equipment, GIS provides improvements in operational safety, compact physical size, aesthetic appearance, in close quarters operation and in relative environmental risk.

Mitsubishi Electric breaker performance, across voltages of 69 kV to 800 kV, employ Mitsubishi Electric’s time-tested single break, pure puffer interrupters. These interrupters are superior to all other alternatives in reliability, duration, simplicity of design and low maintenance costs. SSD also employs one of two Mitsubishi Electric spring spring mechanisms i.e. the next generation torsion bar spring spring (BM-2) mechanism or the pneumatic open-spring close (AM-38) mechanism. The BM-2 is part of a family that many consider the gold standard of spring spring mechanisms in the Industry.

Finally, SSD has been able to incorporate fast acting, disconnecting and ground switches, to substantially reduce size and modularity. SSD has also added options for gang/independent pole operation, single/three phases, test and diagnostic capability and ergonomically designed control access panels.

Advantages of GIS

  • Occupies about 1/10th the space compared to AIS substations
  • Lower frequency and severity of service faults
  • GIS is relatively maintenance free
  • Can be pre-assembled into modules making installation and commissioning relatively easy

The SSD GIS solution is perfect for high density, urban environments, where substation expansion is vital in dealing with expanded power demands, as well as programs like vehicle electrification, grid resiliency projects and new commercial/industrial needs. GIS is ideal for the following environments:

  1. Large cities and densely populated areas
  2. Industrial complexes where reliability in power is vital
  3. Mountainous and other hard to reach areas where long term reliability is vital
  4. Underground substations where environmental isolation is important
  5. Offshore substations, where protection from the environment is important
  6. HVDC transmission system terminal substations

The SSD GIS solution is completely encapsulated and leak free. This, along with other SSD provided counter measures, can provide a high security profile to any substation. The SSD GIS solution is also perfect for rural and suburban environments seeking a better aesthetic adjacent to high end neighborhoods, or the safest and maintenance free substations, where travel time for operational personnel is an issue. By creating compact customer designs, SSD can elevate equipment, and can encapsulate all in leak free metal piping.

Mitsubishi Electric Substation Division (SSD) has the capability to specifically design, manufacture and install air insulted switchgear (AIS) leveraging our complete suite of engineering services to address the unique needs associated with AIS design. In today’s power utility, AIS design revolves around four thematic concepts:

  • SITE ANALYSIS – Expansion of AIS substations, where real estate is finite. Applying SSD’s talented and multiple disciplines to fully evaluating existing or projected build site
  • COMPLEX PROBLEM SOLVING – Power demand shifts in the rural and suburban environments often result in a project where multiple AIS substations must be reconfigured. SSD is able to take on this complexity and execute a multi-site project exhibiting great wherewithal.
  • HYBRID PROJECT DEVELOPMENT – Often times an AIS substation requires configuration of multiple AIS, GIS, FACTS and multi-vendor integrations to achieve success. SSD is not limited to fixed products, but instead can design and impliment custom systems
  • SPECIFIC NEEDS ASSESSMENT – SSD understands that AIS substations are often spread out over a great distance. They may have security, natural disaster risks, weather vulnerability and much more. Our experiences in MELCO, Mitsubishi Electric and SSD all come together to meet our customers special needs.

SSD’s North American engineering and construction workforces prove day in and day out their familiarity and adherence to power utility and local rules, regulations and specifications is incredibly valuable to our customers. This is particularly true in AIS substation construction, where open air environments are complicated work environments.

  1. SSD’s single contractual process – reducing time and saving money
  2. Full turnkey service – instead of multiple contractual entities.
  3. Streamlined project development – reducing change orders and out of scope work.
  4. Mitsubishi as prime contractor – Single, large corporation for peace of mind.
  5. Mitsubishi Electric know-how and expertise – reduces project disparities and compliance failures.
  6. SSD homogenous project management – allows customers to actively participate in the vendor decision process.
  7. SSD 360 view of project – eliminates over engineering and oversizing due to multi-vendor overlaps.

Mitsubishi Electric Substation Division's (SSD) Industrial Substations are often used by large manufacturing facilities, oil and gas storage, metal & mining sites, LNG/petrochemical refineries, government & defense campuses, data & server centers and other large locations that require dedicated ingress or egress of medium/high voltage power. The need for an industrial substation is driven by power needs, but in many cases the need is far different:

  • Protection and isolation of the facility
  • Security and defense of the substation
  • In-house control of the power inputs and outputs
  • Part of a strategy to save money on power costs
  • Integration of onsite energy harvesting and energy storage

Industrial substations have one obstacle that SSD is uniquely able to resolve. This obstacle is that the site of the substation is often limited to property or location already owned. This site could be adjacent to the operations of the client. This site could be inside a building or even elevated. This site could be in close proximity to dangerous chemicals.

Regardless, SSD professional services can work with the client in the following ways

  • site evaluation,
  • ground plane analysis,
  • architecture through civil engineering of buildings/ enclosures/ platforms,
  • project management and construction services to specifically design, manufacture and install substations,
  • managing the wide range of permits, testing and liaison with the power utility, government agencies and other external partners,
  • activation and commissioning of power inputs from power utilities that SSD is comfortable working with.

In urban and densely populated areas, there is a constant pressure to keep up with the power demand, while not expanding the footprint of the power substation or transformer footprint.

Furthermore, there is a good chance that the equipment is housed either underground or within a building. This further limits the footprint.

SSD is uniquely positioned to evaluate the alternatives associated with this particular use case. The use case often forces the power utility to answer some difficult questions:

  1. Do you operate the facilities at loads above their rating, and for how long?
  2. Do you replace the facility, and with what capacity to ensure a lifetime that meets both the financial and power demand needs?
  3. Do you substitute technologies such as transitioning from AIS to GIS technologies?
  4. Do you employ multifunctional control systems that replace or reduce the footprint of the previously installed voltage control or power factoring or energy switching gear?
  5. Do you decide to build two in place of one, and how will that be financed over time?
  6. Do you factor in storm, natural disaster and security countermeasures, and how will that impact the physical structure, the power equipment and the size of the substation?

All of these factors are part of the engineering challenges which SSD has the experience to deal with as well as the expertise to help the power utility narrow choices down to the right one, based on capital expenditure budgets, on cost/risk analysis and based upon long term power substation energy demands.

  • Power utilities and industrial entities have recently been faced with lawsuits associated with wildfires.
  • They are held accountable for power service restoral in coastal areas after devastating floods.
  • They seek to recover from disruptions associated with transformer explosions.

All these examples force a conclusion that emergency and disaster recovery must evolve to emergency and disaster prevention. One of the most vulnerable and statistically problematic points of contention is the risk associated with a relatively high percentage of aging & obsolete substations still in operation today.

  • RISK ASSESSMENT – SSD substation services are fully able to audit and assess risk of 10’s to 100’s of substations, including detailed technical testing.
  • MULTI-SUBSTATION PROJECTS – SSD substation services can even help develop programs that would encompass upgrades to all substations in operation.
  • MULTI-SUBSTATION MONITORING – SSD substation services can accomplish large scale monitoring programs, including the installation of thermographic imaging and networked monitoring, to ensure early warning systems offset the risks presented by natural disasters.

SSD full turnkey services can allow a power utility or a multisite industrial business to entrust emergency and disaster prevention to our knowledgeable and experienced staff. We have experience building some of the industry’s most challenging gas insulated substations. We have had experiences with platform substation and in-building substation construction. We have experience with advanced fire prevention systems and substation monitoring.

Mitsubishi is a large and high-quality organization with the ability to rapidly staff project teams for any massive endeavor. This separates us from other professional services organizations that might be limited in size or scope or both. More importantly, SSD has deep knowledge associated with most of our power utility customers. We have designed, manufactured or sold substation systems into thousands of power utilities over the last thirty years.

The generation, transmission and distribution of power is constantly challenged to ensure power supplied is transported and distributed from point A to point Z, without loss and with optimized network integrity. To enhance controllability and increase power transfer capability, SSD provides power utilities, industrial applications, gas & mining applications and long-distance power transmission with high quality voltage control and power factor technology.

Mitsubishi Electric Flexible AC Transmission Systems (FACTS) provide voltage regulation and power factor management solutions to the Industry that enables qualitative transmission of AC power throughout North America. Today’s power transmission and grid infrastructures are experiencing incredible challenges.

Melco, MEPPI and SSD have continued to provide leadership in the development of FACTS technology. Today’s power grid is under mounting stress as utilities grapple with the rapid retirement of coal power plants, prevalence of renewable energy sources, and load growth into new areas. This combination of load growth supplied by intermittent sources of electric power can create unstable voltage conditions that constrain power system operation.

Today, advanced power electronics systems like Static Synchronous Compensators (STATCOM), Static VAR Compensators (SVCs) and Fixed Series Compensators (FSCs) have automated the process for robust and reliable operation. These solutions stabilize the power system voltage by balancing the supply and demand of reactive power. This results in a tremendous improvement in the overall operation and performance of the transmission system.

SSD has the equipment solutions and expertise to handle a wide range of voltage regulation, power factor control and switching required to ensure the power is precisely delivered to meet the client’s specifications and needs:

  • Thyristor valves to control the inductance and capacitance applied to the system.
  • Capacitor banks used for switching operations within one cycle.
  • Reactors to change the amplitude of the current.
  • Fixed capacitor harmonic filters used to shunt harmonics generated by the TCR branch(es).
  • Coupling transformers used in conjunction with the thyristor valves.
  • Valve liquid cooling systems used for large substation temperature control.
  • Station control systems using a LINUX-based operating system to control all ancillary equipment throughout the substation.
  • STATCOM systems using gate commutated turn-off (GCT) thyristors, which eliminate additional components, wiring and snubber circuits; and result in lower total cost of operation.
  • AC to DC inversion systems ranging from high to medium voltages.

This represents a few of the electric power equipment that can be used to ensure the substation meets the exacting needs of any industrial application.

Customers considering SSD voltage control and power factor technology do so because they are seeking a solution to optimize power delivery (managing network reactive power), to ensure network stabilization with (consistent inductive and capacitive properties), to accomplish this with minimal capital expenditure, and to often achieve this in the minimal physical footprint (preventing the need for additional transmission lines or substation expansion). SSD provides full turnkey designs including:

  • Professional and certified civil, electrical, and structural design and engineering.
  • Design and construction of foundations, steel structures, and buildings.
  • Professional project management and construction resources.
  • Professional and certified system testing and commissioning services.

HVDC-Diamond® High Voltage DC solutions present an opportunity to more efficiently transport power over long distances. Interestingly, retroactive high voltage DC is being touted as the transmission methodology of the future. This revisits the assertions made originally by Thomas Edison. “The advantages of HVDC then became readily apparent. Compared to AC, HVDC is more efficient—a thousand-mile HVDC line carrying thousands of megawatts might lose 6 to 8 percent of its power, compared to 12 to 25 percent for a similar AC line1.”

There are two other important factors to consider in HVDC. First, HVDC transmission allows for elimination of towers and aerial cables using underground and submarine transmission. As power generation becomes more distant from the power consumer, this is essential to all power utilities. Placing towers and aerial transmission has become almost impossible in populated areas. In areas where aerial facilities exist, is the ability to construct a DC plant on existing AC tower paths, replacing AC lines. Thus, delivering more power to the same people, without creating a “not in my backyard” conflict.

Employing SSD HVDC solutions results in the ultimate improvements in the following specific ways:”

  • Lowered cost by avoiding AC transmission line losses, which is a direct function of distance, voltage and power transfer.
  • Considerably friendlier to the future of alternative energy generation and transmission, where high voltage DC power is being generated for transport to traditional grids.
  • HVDC is often necessary as a means of delivering high voltage power across the boundaries of two dissimilar systems. This could be company boundaries, territorial boundaries or national boundaries.
  • Provides a low loss solution, with the most efficient method of transmission technology
  • Enables the controllability of intermittent power
  • Improves environment impact as a result of the smaller towers and right of way requirements
  • Increasing power capabilities up to 3 times more than AC circuits

  • Compress air generation
  • Flywheel generation
  • Pumped hydro generation
  • Thermal generation
  • Flow battery generation

Renewable energy - often referred to as “clean energy” - comes from natural sources or processes that are constantly replenished. This is as compared to nonrenewable, or “dirty energy”, including fuels such as oil, gas, and coal. Nonrenewable sources of energy are only available in limited amounts and take many lifetimes to replenish.

SSD provides two systems within this solution category. The photovoltaic (PV) solar solution includes skid or site build solutions comprised of 2.5MW to 3.36MW building blocks and central inverter technology. The energy storage solution (BESS) includes containerized or building solutions comprised of 1MWh to 200MWh systems configures as equipment only or full turnkey options (i.e. civil, structural and power designed & engineered & built).

These can be supplied as products, as systems, or as turnkey solutions. SSD has the ability to meet the customer need, however complex or simple the project may be. This is an important distinction because it speaks to the most valuable part of our solution offering. Mitsubishi is known for high quality, for excellent customer service, and for extremely attractive warranty programs. In an emerging or growing industry segment such as flexible renewable energy, there is a very diverse set of suppliers. Some of the suppliers are startups with new exciting technology. Some of the suppliers are established, but only offering products. Some of the suppliers are professional services organizations that are learning as they progress. Mitsubishi Electric’s value propositions demonstrate why the choice to work with SSD on renewable energy systems is so compelling.

  • Mitsubishi is one of the largest global technology leaders with a culture for integrity, fairness and high quality. This means that the C&I or power utility customer will have a great assurance that Mitsubishi will stand behind our solution.
  • Mitsubishi Electric, MELCO (Japan) and SSD all are positioned in renewables to be able to select, acquire, integrate, or build the best technologies available into our renewable solution. For instance, the heart of the inverter is the Mitsubishi Insulated Gate Bipolar Transistor (IGBT) which is recognized as an industry-leading building block for power switching and voltage regulation
  • Mitsubishi Electric is a manufacturer of switchgear, transformers, UPS, power control systems, power utility equipment, and much more. Unlike battery manufactures or an engineering company, there is a deep knowledge base and talent that exists in SSD. For instance, in most cases, Mitsubishi Electric already possesses safety and performance compliance with power utility standards. Mitsubishi Electric already manufactures and supplies generation, transmission and distribution equipment to C&I and power utility customers.
  • • SSD can deliver turnkey solutions to our customers or partners. This means that the Flexible Renewable Energy group has access to power system planning, design, engineering, project management, site management, testing, customer service, and administration resources to fully complete any turnkey project.
