配电系统无功补偿技术方案比较

Comparison of technical schemes of reactive power compensation for distribution system

配电网合理的无功补偿,能够有效地维持系统的电压水平,降低有功网损,提高网络输送容量,减少发电费用,因此,确定无功补偿的合理配置和分布非常重要。文章对配电系统的4种无功补偿方式进行了技术经济比较,分析他们各自的优缺点,以寻求一种配电网无功补偿的最优方案。最后对配电网无功补偿工作中遇到的问题提出自己的看法。

Reasonable reactive power compensation methods for distribution networks can keep the systems voltage profile, reduce the active power losses of networks, increase the feeding capability of networks, and cut down the generating costs. Four schemes of reactive power compensation of distribution systems are compared technoeconomically in this paper to seek the optimal. And suggestions are given in view of some problems encountered in reactive power compensation of distribution systems.
