摘　　要：为了分析不同电压控制模式之间的联系,从一个理想化的最优控制模式出发,通过在时间、空间和目标3个方面所进行的合理简化,逐步将其演化为各种实用的电压控制模式,并利用时间-空间-目标三维分类的方法对各种电压控制模式进行了对比。得出了理想化最优控制模式、2层电压控制模式、保优电压控制模式、3层电压控制模式的数学模型。指出各种控制模式之间存在着内在的演化关系,不同的电压控制模式有不同的适用条件,其中3层电压控制模式更加适合现阶段中国电网的特点和需求。The inner relationship of different reactive power and voltage control methods is the research emphasis of this paper. An ideal optimal control method was modified to produce several practical control methods by simplifications on time, space, and objective. Discussion and classification on the three dimensions of time, space, and objective are carried out. Mathematical models are presented for an ideal control method, a two-level control method, an optimization-holding control method, and a three-level control method. Conclusions are drawn lastly on the evolution relationship of these control methods, which are different degenerate forms of the ideal model and designed for different work conditions respectively. The three-level control method is shown to be more suitable for power networks at the present in China.
