Abstract
Calculation of the equipment failure rate is a key point to the risk assessment of power system operation. The condition based mainteinance equipment fault rate algorithm is applied to the risk assessment of power system op-eration, which will improve the accuracy and reliability of equipment failure rate in a certain extent.The power system operation risk assessment methods based on the condition maintenance take full consideration of the existing uncertain-ty in power grid operation, and describe the running risk level of the power grid comprehensively through the five risk index including the line overload, transformer overload, over voltage, low voltage and loss of load.The layer analysis method is applied to the calculation of the comprehensive risk index of power network, which provides a reference frame to the comparison of risk under different operating modes of power grid.Through the practical example analysis, this paper demonstrates the effectiveness of the power system operation risk assessment method based on condition ma-intenance.关键词
