【摘要】 电力设备检修策略的制定和设备运行风险大小息息相关。首先,采用风险理论评估设备运行风险,综合考虑设备故障率及设备退出运行对系统经济性、安全性的影响,通过设备实时状态信息推算出设备故障率,以设备自身资产和资产损失度衡量经济性,以线路过载、变压器过载、电压越限、失负荷等多项指标反应系统安全性;其次,针对设备运行风险评估结果采用ALARP原则进行风险等级划分;最后,依据设备运行风险等级制定检修策略。实例结果表明,通过设备运行风险等级制定检修策略有效可行。更多还原

【Abstract】 Electrical equipment maintenance strategy is closely related with the equipment operational risks.Firstly,Based on risk theory to evaluate equipment operational risk,considering the economic and security influence which caused by the equipment failure rates and equipment out of operation to the system.Calculated equipment failure rate through the equipment real-time status information.Using the equipment assets and asset losses to measure grid economic,and get transmission Line overloading,transformer overloading,the voltage limiting indices including to react grid security;Secondly,the results of equipment operating risk assessment,and adopted ALARP principles to divide the risk rank;according to it;Finally,making maintenance strategy.Example results show that making maintenance strategies according the equipment operational risk grade is effective and feasible.更多还原
