| 摘 要： | 电力系统保护中继电保护装置运行时可靠性指标的定义和计算与电力系统可靠性指标计算、继电保护装置的评价、使用、完善与发展等密切相关.而确定继电保护装置运行状态的内涵则是一个十分关键的环节.过去对于继电保护装置运行状态的定义是否能正确而合理地反映继电保护装置的性能是一个值得进一步深入探讨的重要问题.作者就继电保护装置可靠性指标的内涵和计算提出的看法,可以促进继电保护装置的运行性能的合理评估和保护装置的完善.

| Abstract: | The definition and calculation of operative
reliability indices of protective relayings in power system
protection are closely related to the calculation of reliability
indices of power system and the assessment, application,
improvement and development of protective relaying units. It is
a key link to determine the intension of operative state (i.e., the
definition of correct action and incorrect action) of protective
realyings, therefore, it is an important problem worth to be
further researched whether the performance of protective
relayings can be correctly and rationally reflected by the
definition of operation state of protective relaying in the past.
Here, some opinions about the intension and calculation of the
reliability indices of protective relayings are put forward and it
is hoped that these opinions can actively promote the rational
assessment on the operating performance and the improvement
of protective relayings |
