风力发电机组低电压穿越测试与分析
Test and analysis of low voltage ride through characteristic of wind turbine generator system
摘要
Abstract
With the increasing penetration rate of wind power in power system,the interaction between wind power and electric power system is more and more intense,and the mandatory requirement is developed for the continuous operation of wind turbine under grid fault.The working principle and topology structure of DC unloading circuits were analyzed,and the model of direct-drive permanent magnet synchronous generator (PMSG) system was established.Machine side converter adopted the improved direct current vector control strategy,achieving the smooth and efficient operation of the generator;the grid side inverter control strategy was further improved to enhance the ability of low voltage ride-through (LVRT) of system.Movable LVRT test device was used to perform field testing for PMSG system of a wind farm in Inner Mongolia.The test results meet the LVRT requirements of the national grid.关键词
