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.
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:
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:
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.
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:
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
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:
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.
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.
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:
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:
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:”
Mitsubishi Electric Substation Division (SSD) provides energy storage systems that represent a set of methods and technologies used to store various forms of harvested energy.
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.
