METHOD AND SYSTEM FOR COORDINATED CONTROL OF HIGH-VOLTAGE RIDE-THROUGH OF WIND TURBINE GENERATOR SET

摘要

A method and system for the coordinated control of the high-voltage ride-through of a wind turbine generator set, which method and system belong to the technical field of wind power generation control. The method for the coordinated control of the high-voltage ride-through of a wind turbine generator set comprises: performing real-time monitoring on a wind turbine generator set, so as to acquire monitoring information (S10); comparing a generator-end voltage of the wind turbine generator set with a preset voltage threshold value, and comparing the change rate of the generator-end voltage of the wind turbine generator set with a preset change rate threshold value, so as to respectively acquire comparison results (S20); and according to the comparison results, controlling a current transformer and a low-voltage electric reactor of the wind turbine generator set, so as to complete the coordinated control of the high-voltage ride-through of the wind turbine generator set (S30).
