特殊情况下孤立电网电流保护整定计算

Isolated Power System in the Protection Setting Calculation under Special Circumstances

针对油田、矿场等孤立电力系统在保护装置整定计算过程中出现的一些问题,提出了相应的改进整定方法,使得在供电系统发生故障时,有相应的保护装置可以将故障部分及时从系统中切除,以保证非故障部分继续正常工作。实践证明,该整定方法可以在很大程度上提高电网的运行的安全性、可靠性。另外也详细给出了相应的改造方案,以进一步保证电网安全可靠运行。

This reality,for the oil,mining and other isolated power system in the protection setting calculation of some of the problems occurred during the corresponding improvement proposed tuning method,makes the power system failure,there is a corresponding fault protection device can be removed from the system some time to ensure that non-fault part of continuing work.And proven,the tuning method can greatly improve the security of grid operation and reliability.Another article also details the transformation of the corresponding program,to further ensure network security and reliable operation.
