同一风电场动态无功补偿装置协调运行性能的检测方法
摘要：
本发明公开了一种同一风电场动态无功补偿装置协调运行性能的检测方法，解决了现有技术对风电场配备的两套动态无功补偿装置协调运行性能进行检测时存在失真性大的问题。包括高压侧母线、低压侧母线、电能质量分析仪，完成动态无功补偿装置协调运行性能的电压、电流波形采样；分析下载的电压、电流波形采样数据，软件可自动生成低压侧电压波形、第一动态无功补偿装置电流波形、第二动态无功补偿装置电流波形及高压侧电压有效值曲线；若电压有效值未出现二次超出电压合格范围，说明动态无功补偿装置未发生过度补偿；若电压有效值出现二次超出电压合格范围，说明动态无功补偿装置发生了过度补偿；真实检测出动态无功补偿装置的协调运行性能。
摘要（英）：

The invention discloses a method for detecting the coordinated operation performance of dynamic reactive power compensation devices in a same wind power plant. The problem that in the prior art, when the coordinated operation performance of two dynamic reactive power compensation devices assembled in a wind power plant is detected, the fidelity lacking is serious is solved. The method relates to a high-voltage side bus, a low-voltage side bus and a power quality analyzer and includes the steps of completing voltage and current waveform sampling on the coordinated operation performance of the dynamic reactive power compensation devices, analyzing loaded voltage and current waveform sampling data, wherein software can automatically generate a low-voltage side voltage waveform curve, a first dynamic reactive power compensation device current waveform curve, a second dynamic reactive power compensation device current waveform curve and a high-voltage side voltage effective value curve, it shows that the dynamic reactive power compensation devices do not have overcompensation if a voltage effective value does not exceed a voltage acceptability limit for the second time, and it shows that the dynamic reactive power compensation devices have overcompensation if the voltage effective value exceeds the voltage acceptability limit for the second time, and really detecting the coordinated operation performance of the dynamic reactive power compensation devices.
