基于十七区图的电压无功控制策略研究

Study on the Control Strategy of Voltage and Reactive Power Based on the Seventeen-zone theory

阐述了无功补偿的重要性,分析了变电站电压无功控制的规律和传统九区图控制策略,指出了九区图控制策略中存在的问题;并在此基础上提出了改进的十七区图,克服了补偿装置在运行过程中出现的振荡现象,保证了电力系统的稳定运行。本文还简要介绍了基于人工智能的电压无功控制策略。

This article elaborates the importance of reactive power compensation,analyzes the control law of voltage and reactive power for substation and the traditional nine-zone theory,pointing out the problems in nine-zone theory.The seventeen-zone theory which has been modified is provided based on the nine-zone theory;it can overcome the oscillating phenomenon in operating of the compensating device and guarantee that the power system can operate stably.This article also gives a brief introduction about the control strategy of voltage and reactive power based on artificial intelligence.
