资料介绍

传统依靠电流幅值判断短路故障的方法,在大电流情况下局限性明显,判断时间延长导致整个系统在大的故障电流情况承受较长的时间,增大了系统运行的风险系数。文中提出了一种电流上升率结合电流幅值的方法作为短路判断依据,在分析电流检测和保护工作原理的基础上,设计了基于CPLD的短路电流早期检测和保护系统硬件电路,通过搭建混合式微网智能断路器实验平台,验证了该硬件电路的可靠性。

Limitations of traditional estimation method of short circuit fault relying on current amplitude is obvious in the high current situation,judgment time prolonging leads to the whole system endure longer time in the large fault current,increasing the risk coefficient of system operation.A current rise rate combined with current amplitude as a short judgment basis is presented in this paper.On the basis of analysis of current detection and protection principle,short-circuit current early detection and protection system hardware circuit are designed based on CPLD,the reliability of the hardware circuit is verified by building hybrid micro grid intelligent circuit breaker test platform.
