The voltage and reactive power control has become a distribution network to improve the economy and reliability of the indispensable ways. based on Nine zones in the traditional method and combination of the characteristics of the sub-station, we proposed a fuzzy variable center nine zones control method carried out using the method of integrated voltage and reactive power regulation, through numerical examples and simulation, show that the method is better coordination of re-active power and voltage in real-time control of the contradictions, but also to achieve real-time control for the basic objec-tives of the substation, substation real-time control method for the practical application of a reference value.%变电站电压无功控制已成为提高配电网经济性和可靠性的不可缺少的途径之一。在传统九区图方法的基础上，结合变电站的特点，提出了一种模糊变中心九区图控制方法，利用该方法进行了变电站电压无功的综合调节，通过对算例的计算与仿真，表明该方法较好地协调了无功与电压在实时控制中的矛盾，同时也达到了对变电站实时控制的基本目标，对于变电站实时控制方法的实际应用具有参考价值。
