摘要

分析风电机组脱网事故

提出了风电谐波测试方案

研究风电场并网点、集电线路母线、风电机组等不同电气位置的谐波水平及特征

简要分析了谐波谐振导致风电机组脱网的故障机理

得出谐振是由风电机组箱式变压器感抗和风电机组变流器网侧滤波电容容抗引起

并计算出谐振点谐振频率约为1.1 kHz。最后

结合现场工程实际提出了谐波谐振治理方案

通过仿真结果和现场测试验证了谐波谐振治理的效果。

Abstract

Based on an analysis of wind turbine off-grid accidents

a systematic testing scheme of harmonic resonance is proposed. The harmonics level and characteristic on different test points are researched

including point of connection of wind farm and a 35 kV bus of power collecting line and wind turbine. The mechanism of wind turbine harmonic resonance is analysed and found to be caused by the leakage inductance of wind turbine transformer and filtering capacitance of wind turbine converter on the grid-side. And the calculated result of resonance frequency at the resonance point is 1.1 kHz. In the end

a practical harmonic elimination scheme is put forward

which is proved effective by simulation results and field tests. This work is supported by National Key Technologies R&D Program (No. 2015BAA07B01) and State Grid Corporation of China.
