| 摘 要： | 论述了暂态电压安全的参数裕度与轨迹裕度之间的关系，讨论了暂态电压安全的参数裕度的计算方法;以轨迹裕度为基础、参数裕度为表征，对暂态电压安全性进行评估和控制。根据相应的国家标准和山东电网关于暂态过程中的电压要求的调查报告，确定了描述山东电网暂态电压跌落可接受性准则的二元表，提出对暂态低电压切负荷紧急控制系统的配置和参数整定的思路。最后，利用暂态安全定量分析软件FASTEST-NARI对山东电网低电压切负荷控制方案进行了初步工程设计和量化分析。

| Abstract: | A m ethod of calculating the param eter m argin for transient voltage security is proposed, and the relationship betw een the param eter m argin and the trailm argin is clarified. Moreover, the two-elem ent tables describing the transient voltage dip acceptability for Shandong Pow er Grid are suggested based on both industrial investigation and the relevant standards. The strategy forallocating and setting em ergency controlsystem s on undervoltage load shedding is proposed, and its application to Shandong Pow er Grid is reported. The toolused is FASTEST-NARI, w hich is a quantitative assessm ent toolforboth transientangle stability and transient voltage security. |
