微机式自适应电压速断保护的研究

Research of microprocessor-based adaptive voltage instantaneous trip protection

为了克服传统电压速断保护的动作性能受运行方式变化影响的缺点 ,提出了利用在线实时计算系统电源侧综合阻抗的方法实现微机式自适应电压速断保护 ,分析结果表明它比传统的电压速断保护有着非常明显的优越性。

A microprocessor based adaptive voltage instantaneous trip protection is proposed and analysed.The voltage setting can be automatically online calculated and determined according to current operation condition of power system and the protection zone is enlarged.As a result,the adaptive voltage instantaneous trip protection is more superior than the same conventional ones.
