摘要
在电力生产实践过程中,电力设备通常采用故障后更换的策略,这不仅会对电力设备的备件贮存提出针对要求,而且某些重要设备故障后造成的非预期停机也会对电力生产造成较大的损失。基于此类设备的更换策略存在的问题,首先,将电力设备的历史故障数据作为截尾样本,对电力设备的故障时间分布进行拟合;然后,建立了最小停机时间更换模型,并确定了电力设备的预防性更换间隔时间;最后,将该方法应用于惠州蓄能水电厂运行过程中某工业控制器的预防性更换间隔时间的计算中,展示了该模型的可用性。
In the practice of electric power production,the strategy replacement after failure is usually adopted for the power equipment,which will not only make demands on the storage of spare parts for power equipment,but the unplanned shout down caused by the failure of some important equipments will cause great losses to power production.Based on the problems of the replacement strategy of such equipment,firstly,the fault time distribution of the power equipment is fitted by taking the historical fault data of the power equipment as the truncated sample.Then,the minimum shutdown time replacement model is established,and the preventive replacement interval of power equipment is determined.Finally,the method is applied to the calculation of the preventive replacement interval of an industrial controller during the operation of Huizhou Pumped Storage Power Station,and the availability of the model is shown.
