自适应电流保护

供电线路运行的可靠性、经济性、安全性直接影响广大电力用户,论述了供电线路的自适应电流保护.其保护定值由当前的系统运行方式和故障状态决定,大大扩大了保护范围,且降低了保护最低选用条件.;Based on the fact that the security, economy and credibility in the power supplying systems affect numerous consumers, this paper discusses the current adaptive protection for the power supplying lines. The adaptive current protection can automatically calculate the setting values based on the fault type and the system impedance, so it can extend the protection and bring the selection criteria down
