【摘要】 为限制短路电流,避免大量更换断路器,需在高压线路中装设串联电抗器。分析了在线路上加装串联电抗后对线路保护的影响,考虑了适应于串联电抗的线路电容式电压互感器(CTV)布置,提出了适合于线路、串联电抗器的保护配置方案。对带有串联电抗器的线路,分析了线路重合闸的适应性及相应的重合闸实施方案。更多还原

【Abstract】 In order to restrict short circuit current and avoid from replacement of a great number of older circuit breakers,serial reactors are installed on EHV transmission line.The paper analyzes the effect of line serial reactors on line protection,considers line CVT’s arrangement appropriate to serial reactors,and propose a protection configuration accordingly.It also analyzes adaptability of the line auto-reclose and corresponding reclose scheme.更多还原
