摘要
二级电压控制是一种新型的电压控制方式,它首先是将整个电力系统分成若干彼此电气距离较远且相互近似解耦的控制区域。为此,研究了二级电压控制模式下的分区方法,提出了一种结合阈值搜索和动态分散的电压/无功分区算法,即用阈值搜索的方法得到初始的分区后,用动态分散法对初始分区进行调整和改进.此方法基于系统的物理特征,不用修改网络模型,不需分析特征值,具有很快的计算速度.通过与传统方法的比较,证明该分区方法是合理可行的.
Secondary Voltage Control is a new way of voltage control, firstly the power system is divided into many control areas whose electric distance is remote. The partitioning method of secondary voltage control is studied and an algorithm that combination of the threshold search and dynamic scatter is presented. That is, the initial grouping scheme is obtained by searching the threshold value. The dynamic scatter method then is used to regulate and improve the initial results. The method is based on systemg physical character, it's unnecessary to modify the network's model and analysis the eigenvalue, so the compute rate is fast. Through comparing the method and the traditional methods, this method is proved to be a reasonable and feasible partitioning scheme.
