摘要
分析了电力市场环境下传统的电力系统电压安全评估方法的缺点,提出了基于风险的电力系统低电压安全预警。该方法充分考虑了事故发生的可能性和事故发生对系统电压造成的后果,综合得出了系统的低电压风险值,根据该风险值对系统的电压安全情况进行了分级预警。IEEE30节点的仿真算例说明了该方法的有效性。
To solve the defects of traditional voltage security assessment methods for power systems in the electricity market, the risk-based low voltage security forewarning is proposed which fully considers the probability and consequence of low voltage accidents. Based on that, the low voltage risk index was quantified and then used for classified voltage security forewarning. Simulation of the IEEE 30-bus system proves the method effective.
