Technical Transformation of Parallel Operation of No.1 and No.2 Auxiliary Transformers in Yunnan Huadian Lvshuihe Power Plant
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.
