SVC装置在风电并网中的应用及其自动电压控制

Application of SVC Device in Grid-connected Wind Power and Its Automatic Voltage Control

系统无功功率的供给不足是风电场电压崩溃的主要原因之一,需要采取措施对其进行有效调节。对此,文章介绍了一种应用于风电场的TCR型SVC无功补偿装置,该SVC装置以电压为控制目标,可以接受风电场统一自动电压控制,能达到稳定电压的效果。

System reactive power in short supply is one of the main reasons for wind farm voltage collapse, so actions should be taken to effectively regulate wind farm reactive voltage. It presented a TCR type SVC reactive power compensation device applying in wind power and took bus voltage as the main control goal, and unified power grid AVC（automatic voltage control） was accepted to steady voltage with this method.
