Abstract
With the continuous expansion of the power system scale and the continuous improvement of the complexity, the relay protection device is the core equipment for ensuring the safe and stable operation of the power grid, and its reliability analysis has become an important topic in the power system research. This paper aims to explore the reliability of the relay protection device in the actual operation, and quantify the failure mode and its influencing factors through the comprehensive evaluation model based on the fault tree analysis method and Monte Carlo simulation. When the relay protection device of a typical power system is selected as a case, combined with the historical operation data and field test results, an improved reliability evaluation index system is proposed, which can more accurately reflect the performance of the device in the dynamic operation environment. The results show that the model can effectively identify the key weak links of the relay protection device, and provide a scientific basis for the optimization design and operation and maintenance strategy.
