## 配网无功功率优化问题研究

Abstract
Whether distribution network can run safely and economicly depands on the reactive power compensation. However，the lack of reactive capacity in Chinese distribution network is still terrible. For example，its losses of system and difficulties to running stablely. So study on distribution network reactive power compensation of distribution network safe operation and improve the economic efficiency of power grid has important significance.
In this paper, I analyze two directions of the reactive compensation. One is the study of reactive power compensation device， the other is the study on the theory of reactive power compensation. Firstly，I analyse  the frequently-used working principle of reactive power compensation device. Secondly， the basic theory of reactive power compensation were studied. Then the paper analyzes the calculation method of network losses. Finally， it probes into the reactive power optimization algorithm based on semi ergodic.

Keywords: power distribution network,  reactive power compensation, reactive power optimization， reactive power compensation  device
