Abstract: The voltage stability problem of large-scale wind power collection system is key factor to power grids. Dynamic reactive power compensation devices on wind farms are effective for controlling reactive power and voltage of wind power system. However, in field operation process, reactive power compensation device has problems including unreliable operation, slow dynamic response time which does not meet power grid requirement. Some effective correction measures are proposed based on testing results. Practice shows that reactive power compensation device performance testing and rectification work can effectively improve device performance, system operation safety and wind power accommodation capability.

Key words: dynamic reactive compensation device, dynamic response time, power quality, reactive power and voltage control
