摘要
电压(负荷)稳定性目前已成为电力系统规划和运行中主要关心的问题,系统中的功率传输特性将直接影响到系统的电压稳定。针对现在系统中功率传输的很多分析方法都具有繁琐复杂、不易快速直观揭示问题本质的特点,本文提出来一种基于电力系统简单模型的无功功率传输特性分析方法。根据此方法可迅速得出系统无功功率传输的特性及对电压稳定性的影响,对电力系统电压稳定性分析具有一定实际意义。
Voltage (load) stability has become the main concerns of power system planning and operation. The power transfer characteristics will directly affect voltage stability of system. According to many analysis methods of power transmission system which are cumbersome and complex and difficult to quickly and intuitively reveal the nature of problem, a transmission characteristics analysis of reactive power based on a simple model of power system is proposed. Using this method can quickly arrive at the reactive power transmission characteristics of system and the impact on voltage stability. It has some practical significance for voltage stability analysis of power system.
