【摘要】：设备故障率的计算是电网运行风险评估中的关键环节,将基于状态检修的设备故障率算法应用到电网运行风险评估中,在一定程度上提高了设备故障率的准确度、可信度。基于状态检修的电网运行风险评估方法充分考虑了电网运行中存在的不确定性,通过线路过载、变压器过载、过电压、低电压和失负荷五项风险指标较全面地描述电网运行风险水平,且应用了层次分析法计算电网综合风险指标,为对比电网不同运行方式下的风险大小提供了参考依据。通过实际算例分析,验证了基于状态检修的电网运行风险评估方法的有效性。
[Abstract]:The calculation of equipment failure rate is a key link in the risk assessment of power network operation. The application of equipment failure rate algorithm based on condition-based maintenance to power network operation risk assessment improves the accuracy and credibility of equipment failure rate to a certain extent. The risk assessment method of power network operation based on condition-based maintenance takes full account of the uncertainty existing in the operation of the power network, through line overload, transformer overload, overvoltage, The five risk indexes of low voltage and load loss describe the operation risk level of power network more comprehensively, and apply AHP to calculate the comprehensive risk index of power network, which provides a reference for comparing the risk of different operation modes of power grid. The effectiveness of the risk assessment method based on condition-based maintenance is verified by a practical example.
