鸡西电网无功补偿节点的现状分析及建议

Analysis and advice on reactive compensation bus in Jixi Grid

合理的无功电源配置能有效地降低网损,保证电压质量,预防事故发生或防止事故扩大,从而提高电力系统运行的经济性、安全性和稳定性,合适的无功补偿节点与补偿容量的选择还可以减少资金的投入。阐述了鸡西电网目前无功补偿点选择的方法,对鸡西电网的每个节点进行灵敏度分析,选择部分节点做为无功补偿的候选节点,对当前鸡西电网无功补偿节点的选择提出相应建议。

Rational reactive power supply configuration works well in reducing loss,guaranteeing voltage quality and preventing accidents so as to enhance the economy,security and stability of electric power operation and realize cost reduction by applying proper reactive compensation bus and capacity.This paper expounds how Jixi Grid selects reactive compensation bus,analyzes the sensitivity of each bus in Jixi Grid,picks out partial buses as for candidates of reactive compensation ones and gives advice on how to select reactive compensation bus for Jixi Grid in the current situation.
