高压直流输电系统的安全稳定运行依赖于换流站内各设备的正常运行,通过在线监测各设备的状态量来评估其健康状况,对制定状态检修策略有重要意义。分析了状态检修的原理,换流变压器是换流站内的核心设备,介绍了换流变压器与普通变压器的不同之处,总结了换流变压器、换流阀、滤波器等设备评价其健康状况的各性能指标和状态量,并讨论了各自检修的特点。
The safe and stable operation of HVDC transmission system depends on the normal operation of con- vertor station equipment. It has important significance in condition-based maintenance through the online moni- toring equipment state to evaluate the health condition. This paper analyzes the principle of the condition-based maintenance and the differences between converter transformer and common transformer. Converter trans- former is the core equipment in converter station. Each performance index and quantity of state using in evalu- ating the health status of converter transformer, converter valve, filters and their maintenance characteristics have been summarized.
