摘　　要：基于故障假说的分析算法能够进行一些初步的保护动作行为分析和开关动作行为正确性评价,辅助相关人员进行进一步的故障排查。这种算法将故障相关的模拟量和数字量作为输入,依据一定的故障分析原理,计算出保护动作的期望状态和开关动作的期望状态,并与实际的动作状态进行比较,从而选出最符合实际情况的一个假说就作为故障诊断的结果。The analysis algorithm based on fault hypothesis can carry out some preliminary analysis of protection action behavior and correct evaluation of switch action behavior, and assist related personnel to conduct further troubleshooting. This algorithm takes the analog and digital parameters as input, calculates the expected state of the protection action and the expected state of the switch action according to a certain fault analysis principle,and compares them with the actual action state, so as to select a hypothesis that most accords with the actual situation as the result of fault diagnosis.
