电网无功补偿容量的选择

Selection of Reactive Power Compensation Capacity in Power Grid

根据工程实践经验,介绍了几种常用的无功补偿容量选择方法。详细描述了根据提高功率因数、降低线损、提高末端电压、经济无功负荷的需要及统计估算法等来选择无功补偿容量,并进行了相关计算。所介绍的选择方法为确定经济合理的无功补偿容量提供了参考价值。

According to practical engineering experience, several common ways of selecting reactive power compensation capacity were introduced, such as by increasing power factor, lowering line loss, raising the terminal voltage, the need for economic reactive load and statistical estimation method, and relevant calculation was carried out. The selecting way introduced provides reference for confirming economic and resonable reactive power compensation capacity.
