基于多状态信息修正优化组合的电力设备故障率计算方法
Calculation Method for Fault Rate of Electric Power Equipment Based on Multi-state Information Amendment Optimization Combination
摘要
Abstract
Forecasting method for multi-state information amendment optimization combination is used to establish three kinds of models of state amendment optimization combination for forecasting fault rates of electric power equipments,which are respectively affected by weather,insulation aging of materials and equipment overhaul. In allusion to characteristics of various stochastic influencing factors,extensible principle is applied in forecasting fault rates of three kinds of weather state models. Joint failure probability density method based on three parameters Weibull distribution-Copula function is used for calculating fault rate caused by insulation aging and Holt-Winters model is used to estimate fault rate due to equipment over-haul. Predicted value with high degree of accuracy is worked out by using fruit flies optimization algorithm to weight and op-timize the fault rate of each submodel. Taking one power system in some region for an example,the analysis results indicate that these models can effectively improve forecasting precision of fault rates,meanwhile the fruit flies optimization algo-rithm is efficient to solve the forecasting problem of multi-state information amendment optimization combination.关键词
