摘　　要：为满足电力系统在稳态运行条件下和暂态过程中的多种电压稳定性约束要求,根据现有无功补偿设备所具有的动态、静态不同的特性,基于模糊聚类法、动态电力系统理论和优化方法,研究了电力系统不同的运行方式下混合配置并联电容器组、SVC的无功规划模型及方法.在IEEE30节点系统算例分析中,首先基于模糊聚类理论及最优化理论采用成本较低的并联电容器组进行满足静态稳定约束的无功规划;然后利用SVC的快速响应特性,基于动态电力系统的理论模型进一步实现了不同工况下考虑严重故障后短期稳定约束的电力系统无功规划.算例分析表明,有效配置多种类型的无功补偿设备资源,能够在保证经济性的同时,实现满足不同稳定约束要求的无功规划.To satisfy the different voltage stability constraints at different load levels for both stability operation condition and transient process,based on the different dynamic or static operation characteristics of reactive power compensators,the mixed allocation of shunt capacity bank（ SCB） and static var compensator（ SVC） were investigated using fuzzy clustering method,dynamic power system theory and optimization method under different operation levels. In the IEEE 30-bus system case study,reactive power planning（ RPP） with static stability constraints was firstly carried out based on the fuzzy clustering method and the optimization method using the lower cost SCB,then RPP with short term stability constraints at different load levels and contingencies was further investigated by the help from dynamic characteristics of SVC. Study results indicate that the optimal allocation of different types of VAr devices can satisfy different stability constraints while ensuring economy requirements.
