摘要
高压断路器智能合闸装置可以解决长距离输电线路合闸时所产生的过电压的问题。对高压断路器智能合闸装置的基本原理及应用范围进行了介绍,特别对运用在江陵换流站的高压断路器智能合闸装置的安装调试情况进行了总结和分析。从试验的结果反映只要准确设置开关的固有合闸时间,开关就能在交流电压过零点附近合上,产生的过电压就比较小,能够满足系统对过电压的要求。这可为同类产品在电力系统中的运用提供参考。
Circuit breaker with artificial intelligence technology can decrease overvoltage during closing long-distance transmission line. It introduces the basic theory and application of circuit breaker with artificial intelligence technology. Especially, it analyses and summarizes practical application of installation and commission about circuit breaker with artificial intelligence technology in Jiangling converter station. Experimental result shows circuit breaker with artificial intelligence technology can decrease overvoltage and meet requirement of power system voltage, after it sets exactly close time of circuit breaker, and the circuit breaker can close in the cross zero of AC voltage. At the same time, it can improve power system stability and power quality. It will supply reference for installation and commission of the same products in the power system.
