Mitsubishi Electric to Build HVDC Verification Facility in Japan

Oct. 24, 2016
Mitsubishi will launch VSC-based HVDC systems business globally.  

Mitsubishi Electric Corp. will enter the global market for voltage-sourced converters (VSC)-based high-voltage direct current (HVDC) systems with a new HVDC verification facility to be built at its Transmission and Distribution Center in Amagasaki, Japan, by 2018. The company is targeting more than US$500 million in global orders for HVDC-Diamond systems by 2020.

HVDC systems are expected to reduce CO2 through the efficient integration and expansion of renewable energies, such as photovoltaic and offshore wind power. HVDC-Diamond systems will use the company’s own high-voltage insulated gate bipolar transistors (HVIGBT), which are insulated for high voltage and designed for large current ratings to reduce the number of sub-modules. The parallel connectivity of the HVIGBT devices in each sub-module allows for a flexible design to meet wide-ranging needs for power transmission capacities in the global market for VSC-based HVDC systems.

HVDC-Diamond will offer high reliability through the use of high-speed control and protection systems. Optimized control functions with appropriate hardware configuration will comply with system requirements for stable and continuous operation, even during faults on the AC network such as lightning strikes. Protection systems with high-speed
response will ensure all equipment can be protected from high currents generated at the time of DC faults within the HVDC system.
