| 摘 要： | 无功功率不能远距离传输,电压/无功是一个局部问题.结合电力系统分区与电压稳定灵敏度分析确定无功电源最佳配置地点的方法,将电力系统分区的思想应用于电力系统无功配置,利用"电气距离"把电力系统分成几个耦合强的小区.该方法使无功电源得到合理的配置,无功补偿分区域平衡.经过仿真计算比较,该方法可找到电力系统无功电源的最佳配置地点,并对提高电力系统的电压稳定性有很好的效果.

| Abstract: | Reactive power cannot be transmitted over long distances,voltage stability is considered as more of local problem rather than a system global problem.A new method of combination network partitioning and voltage stability sensitivity for optimal allocation of reactive power sources is presented in this paper to enhance voltage stability.The concept of electrical distance is introduced to partition a power network into strongly connected sub networks.By applying this approach,the reactive power sources can be allocated most reasonably,reactive compensation balances in every zone.The simulation results indicated that the method is practicable and effective to improve the voltage stability of power systems. |
