【摘要】 地磁感应电流(简称 GIC)对电力系统可能造成的有害影响,国外很多国家进行过大量的研究,但在国内开展的不够广泛。随着我国大电网系统的不断发展,将形成大量东西走向的超高压、大容量、远距离输电线路。我国部分地区的地理位置和地质条件与受到过 GIC 影响的一些国家相似,我国电网是否存在 GIC 问题需要进行研究。本文在对电网 GIC 机理特征、我国电网的可能影响分析基础上,提出先从监测入手研究我国电网 GIC 问题,同时对电网 GIC 的测量方法、监测系统的设计等问题进行了论述。更多还原

【Abstract】 Geomagnetic induced current(GIC)may have a harmful effect on power system. A lot of research have been done in many countries abroad,but in China it is not enough.With the development of big power network in China,many extra-high-voltage,large capacity,long distance transmission lines will be built from west to east.Because of the similarity of location and geographical conditions between some areas and countries effected by GIC,the research should be done to know whether GIC can effects China’s power system or not.The paper analyses the mechanism and characters of GIC and possible effects on power system brings forward that GIC problem of power systems should be researched from its monitoring,and presents measure methods of GIC and device of monitoring system.更多还原
