The first unit of the wind power virtual synchronous machine project of the State Grid Scenery Storage and Loss Demonstration Project, which was undertaken by Xuji Wind Power Technology Co., Ltd., successfully completed the on-site reconstruction and commissioning work, and realized automatic grid-connected operation, which marked the world's first wind power virtual synchronous machine put into trial Operational phase.
It is understood that wind power is relatively random, and can not participate in the frequency regulation and regulation of the power grid like hydropower and thermal power, and strongly support the power grid. With the increasing proportion of wind power in China, it will not be conducive to the safe and stable operation of the power grid. The wind turbine with the function of the virtual synchronous machine can simulate the power generation characteristics of the synchronous generator, and has the ability to participate in the power system frequency modulation and voltage regulation independently to maintain the stability of the grid frequency and voltage. It is a true grid-friendly fan. Previously, there were no wind turbine manufacturers at home and abroad who knew the technology.
Xu Jifeng Electric Power Technology Co., Ltd. took advantage of the advantages of Guowang Yubei Company's wind storage and storage demonstration wind farm, and took the lead in researching the function of wind turbine virtual synchronous machine in China. After a large number of theoretical analysis and simulation calculations in the previous period, and related tests and tests in the workshop, the wind turbine hardware and software transformation plan was finally determined, and the virtual synchronous machine of the first wind turbine of the wind and light storage demonstration project was started on November 24, 2016. Transformation work. Xu Ji on-site remodeling personnel overcame the unfavorable factors such as severe weather and heavy snowfall on the scene. After more than a month of hard work, the on-site reconstruction and commissioning of the first unit was completed on December 29, 2016, and the transformation of other wind turbines was completed. The work laid the foundation. This also marks a further step forward in the research and development of Xuji Wind Power Technology Co., Ltd., and established an industry leading position in the frontier technology of wind turbines.
