无人值班变电站巡视周期的仿真计算

为保障变电站巡视工作的合理性和有效性,以可靠性为中心,基于故障树分析法和层次分析法,利用变压器、断路器、TA、TV、隔离开关等变电站设备的缺陷信息,通过蒙特卡罗分析法建立了计算巡视周期的仿真模型;计算了不同可靠度要求下的巡视周期;提出了一种确定变电站巡视周期的仿真计算方法。该方法利用Monte-Carlo法模拟各种设备缺陷时间的随机性,适于设备的状态维修,为更加合理制定无人值班变电站巡视周期提供了一种方法。

Simulation of Inspection Period for Non-attended Power Substation

In order to ensure the effectiveness of inspection work of substation,based on the defect information from the components of power transformers,such as circuit-breakers,TA,TV and disconnectors,the simulation model to calculate the inspection period is formulated with the Monte-Carlo simulation,fault tree analysis and analytic hierarchy process method,and calculating the inspection period under different reliability levels.The inspection period at different reliability requirement is calculated and the simulation calculation method to determine the inspection period is proposed.This method simulate the time randomness of various device defects based on Monle-Carlo simulation,it is suitable for condition based maintenance,and provides a tool to determine the inspection period for a non-attended power substation.
