智能变电站二次设备检修及预警方法研究

Study on Maintenance and Early Warning for Secondary Equipment of Smart Substations

在智能变电站电力设备的运维中,为了提高电力设备的运行可靠性,需对运行中的设备实施预警,以此来优化检修策略。基于此,介绍了电力设备检修优化预警技术。首先对智能变电站电力设备的局部检修场景进行分析,然后针对不同的检修场景分析了相应的预警方法,最后以某地区智能变电站电力设备检修为案例,对二次设备检修优化方法进行了阐述。结果表明,和传统的检修方法相比,采用该优化方法能够显著降低设备及系统运行风险、节约设备检修资源。

In the operation and maintenance of power equipment in smart substations,in order to improve the operation reliability of power equipment,it is necessary to implement early warning for the operatingto optimize maintenance strategy.This paper elaborates the optimal early warning technology for power equipment maintenance.Firstly,partial maintenance scenarios of smart substation power equipment are described,and then the corresponding early warning methodsareanalyzed according to different maintenance scenarios.Finally,taking power equipment maintenance in a practical smart substation as an example,the optimization methods are summarized in detail.The results show that compared with traditional maintenance methods,the optimal maintenance method analyzed in this paper can significantly reduce the operating risk of equipment and system and save equipment maintenance resources.
