摘　　要：《电力安全事故应急处置和调查处理条例》的实施明确了稳定控制系统切负荷等同于故障损失负荷,对电网运行和稳定控制系统管理提出了更高要求。将先进的风险管理理念引入稳定控制系统配置和日常运行管理,梳理了稳定控制系统的风险因素及其后果,通过将电力安全事故责任代价转化为可承受的经济损失代价期望,提出了涵盖国民经济损失、电力安全事故法律责任和罚款损失的稳定控制系统风险评价指标。在此基础上,提出了基于风险的稳定控制系统配置方案决策和风险管理方法,利用风险代价不能大于风险转移代价的标准表征稳定控制系统风险承受能力,提出基于风险代价和风险转移代价之和最小原则的稳定控制系统风险应对策略优化方法,以实际算例证明该方法可降低电力系统运行风险。Higher requirements are made for the management of stability control system by Ordinances of Electrical Security Accident Emergency Disposal and Investigation, which makes it clear that load shedding by stability control system is equivalent to the loss of load under faults. The advanced risk management concept is introduced into the stability control system configuration and daily management. The risk assessment index of stability control system is put forward including economic loss, legal liability of electrical security accident and penalty loss. The legal liability of electrical safety accident is converted to an affordable economic loss cost. On this basis, the decision-making method of stability control system configuration and risk management are proposed. The stability control system risk tolerance is characterized by the criterion that the risk cost must be less than the risk transfer price. The optimization algorithm of stability control system risk management is proposed based on the principle that the sum of risk cost and risk transfer cost should be minimum. That the risk management method can greatly reduce the operation risk of power system is verified by an actual power system.
