Recently, China enterprises TBEA successfully developed the world's first UHV HVDC converter valve, which marks the TBEA for the first time in the world will be increased from the highest level of technology of flexible DC + 350 thousand to + 800 thousand volts volts current voltage level, the transmission capacity of 1 million kilowatts of existing from the highest level to 5 million KW, opened a new era of hvdc.
Converter valve is the heart of flexible DC transmission. It is the bridge between DC and AC. It is the most technical and challenging in the flexible DC main equipment. TBEA R & D team from the beginning of September last year, the key technology research and equipment development, integrated engineering design and other aspects of a comprehensive and in-depth study, analysis and demonstration, which lasted 9 months, successfully developed the world's first UHV flexible DC converter valve. According to reports, the product can solve the existing new energy power to the large scale and long distance transmission, can only rely on thermal power and bale delivery or local consumptive close bottleneck, will effectively promote the large-scale use of new energy power.
