【摘要】 针对电缆-架空线混合线路故障区间定位困难的问题,文中提出了一种面向区域电网的电缆—架空线混合线路故障区间判别方法,该方法主要基于柔性光学电流互感器(TA)和智能变电站技术。具体介绍了区域电网故障区间判别的整体方案、装置实现、检修和异常处理机制。实际运行经验表明,该方案在区域电网内发生故障后可快速准确识别出故障区间,实现故障的快速定位和检修,加快故障后系统恢复供电。更多还原

【Abstract】 This paper proposes a new method to discriminate the faulty zone for cable-overhead mixed lines in regional power grid based on Flexible Optical Current Transducer(FOCT)and smart substation technology. The overall scheme of the new method, as well as the device realization, maintenance and error handling are discussed in details. The practical application of the method indicates that it is effective to discriminate the faulty zone in regional power grid.更多还原
