摘要
自适应继电保护是电力系统继电保护发展的必然趋势,其定值的自适应性是体现保护自适应的重要方面。本文采用局部控制原理,当系统运行方式改变时, 只需对受电力系统运行方式变化影响的部分继电保护装置整定值做出修正即可,克服了传统方法定值过于保守的缺点,提高了继电保护定值适应电力系统运行方式变化的能力。
Relay protection will finally develop towards the direction of adaptive protection. The adaptability of relay values is a important reflection of adaptive protection. According to independent control theory, when system＇s operating mode changed, we need to remand partial relay values only, which are effected by the change. This method overcomes the shortcoming of traditional method and prompts the relay＇s adapting capability to the changes of power system＇s operating mode.
