摘　　要：变压器是电力系统中最重要的电气设备之一,在电力系统有“承上启下”之作用且一般需要不间断长时间运行,为了使变压器安全经济运行及提高供电的可靠性和灵活性,在运行中通常将两台或以上变压器并列运行。文章主要对绿水河电厂二级站1、2号厂变无法并列运行的原因展开分析及技术改造措施做具体讨论。因技改后的变压器运行方式及其经济效益等达到了预期目标,希望对同行业的其他单位,如若遇到此问题时能够提供解决问题的思路。Transformer is one of the most important electrical equipment in the power system.It plays a"connecting role"in the power system and generally needs to run continuously for a long time.In order to ensure the safe and economic operation of transformers and improve the reliability and flexibility of power supply,two or more transformers are usually operated in parallel during operation.This paper mainly analyzes the reasons why the No.1 and No.2 auxiliary transformers in the secondary station of Lushuihe power plant can not operate in parallel and discusses the technical transformation measures.Because the operation mode and economic benefits of the transformer after the technical transformation have reached the expected goal,we hope to provide ideas for other units in the same industry to solve the problem if they encounter this problem.
