摘　　要：“九区图”理论一直是电压无功控制领域的经典的控制理论,但也存在运算分析的信息具有分散性和随机性的问题,实际表现为控制设备频繁调节。文中提出一种与“九区图”所选择的控制对象角度不同的电压无功综合控制原理——“五区图”原理,并从数学模型、软件实现、定值规范等几个方面对两类原理进行了比较。用功能强大的MATLAB软件仿真得到不同参数时的结果。分析表明,“五区图”是一种控制精细、实现容易的电压无功综合控制原理。'Nine-zone' theory is the classic theory of the synthetical control of voltage and reactive power, while with problems such as the dispersivity and randomness of the data for calculation and analysis, which causes the unexpected frequently operations of devices. This paper presents a new theory with operation oriented--'five-zone' theory. And it is compared with the 'nine-zone' theory in some respects such as mathematical model, software implementation, fixed value system. Furthermore, Matlab, a powerful calculating and simulating tool, is used to simulate the control effects, which indicate different results under different parameters' values. The analytical result demonstrates that this new 'five-zone' theory can provide a control theory with high precision and simple implementation on solving the problem of synthetical control of voltage and reactive power.
