配电网无功优化与控制研究

Reactive Power Optimization and Control of Distribution Network

配电网处于电网的末端,普遍存在着负荷分散且波动较大、供电半径长、功率因数低、无功功率不足等问题,线路电能损失和电压损失相当严重。对配电网进行无功优化可以直接提高负荷点电压质量,减少线损,提高供电企业的经济效益。文章重点研究了配电网无功优化算法,在此基础上设计开发了配电网无功优化系统,并对无功优化控制方式进行了研究。

The distribution network is located at the end of the electric power network with general features such as scattered load,great power fluctuation,long power supply radius,low power factor and inadequate reactive power,in which the power loss and voltage loss are great.Optimization of the reactive power can directly improve the voltage quality of loads,reduce power loss,improve the economic benefits of the power supply companies.In this article,the algorithms of the reactive power optimization in the distribution network are researched and software is developed based on the algorithms,and control modes are studied.
