摘要
本文通过介绍电压稳定性的基本概念,建立了电压稳定性的灵敏度及充裕度判据,提出了利用潮流与灵敏度分析相结合来求取系统无功裕度的方法。通过实例讨论了节点电压相角及系统无功补偿情况对电压稳定性判据的影响。
This paper introduces the basic concepts related to voltage stability sensitivity and margin criteria of voltage stability. The method to calculate the system reactive power margin is presented by combining load flow program with sensitivity analysis technique. Finaly, the influence of voltage phase angle and reactive compensa- tion on criteria of voltage stability is discussed.
