| 摘 要： | 电网运行风险评估可以综合考虑扰动事件发生的可能性与严重性,是电网确定性安全分析的有益补充.分析在线环境下运行风险评估与传统可靠性研究之间的关系,讨论在线运行风险评估的特性和关键问题;重点探讨瞬态时变的设备停运模型、缺乏统计数据情况下的建模方法、快速评估算法和基于风险决策模型的数学含义等。运行风险技术可以从系统和设备2个层面对导致系统故障的累积性风险因素和突发性风险因素进行建模,并可以应用到状态检修优化决策等领域,具有广阔的应用前景.

| Abstract: | Power system operation risk assessment can synthetically analyze the likelihood and severity of disturbance events.It is a useful complementarity for power system security analysis.The relationship between the operational risk assessment and traditional reliability evaluation is well analyzed in this paper.Some key problems existed in online operation risk assessment are discussed.The time-varying component outage model,the component outage model with limited statistical failure data,some fast state assessm... |
