摘要
根据临界点条件 ,对电压稳定弱节点紧急无功补偿模式进行了研究 ,提出了“预支模式”和“分级跟踪模式”两种紧急无功补偿的调控模式 ,并对其补偿效果进行了分析。探讨了“预支模式”有可能使紧急无功补偿进入误区的问题 ,推导出每次投入电容器的上限值 ,指出将静止无功补偿器(SVC)用于“分级跟踪模式”
Based on the critical conditions, the patterns of emergent reactive po wel compensation for voltage stability are researched. Two patterns. prepaid pattern and grading and tracking pattern. of e mergent reactive power compensation are presented. and their effects are analyzed. The question is investigated that the prepaid compensation pattern has the possibility to bring the compensation into wrong area, as a result the upper 11m it of the capacitor needed to put into operation each time is inferred. The voltage stability of week node can be improved effect ively by using SVC for tracking compensation.
