Abstract Protection system has a significant impact on the stable operation of power system, its reliability has been an important topic concerned by power workers. In allusion to the deficiencies in reliability assessment of protection system, such as protection characteristic and sequential characteristic of protection action could not be described accurately in reliability assessment models, an instantaneous failure probabilistic model of protection elements was presented and a new risk probabilistic assessment flow was proposed after establishing reasonable risk indices. An application sample of distance protection risk assessment in an actual power network was given, the results show that the proposed method could be used to find weak links of protection system and detect protection problems that could not be reflected by other systems, as well as to supply redundant information for systems such as online verification and modification of protection settings.

Key words： Protective relay operation risk probability assessment sequential characteristic
