摘要
换流阀是统一潮流控制器(UPFC)的核心,而水冷却系统则对保证换流阀的安全可靠运行具有十分重要的作用。以换流阀水冷却系统为研究对象,从内冷却系统和外冷却系统两方面对其结构进行了详细分析,采用类比法搭建了UPFC水冷却系统结构的电路结构,明确了系统中各个模块的结构和组成,最后对串联水路和并联水路进行了比较,讨论了并联水道流量分布不均匀的问题。
Converter valve is the core of Unified Power Flow Controller（UPFC）. Water cooling system, as the ＂guardian＂ of converter valve, is very important for its safety and reliability. In this paper, the structure of water cooling system is studied.First, a detailed analysis of the structure is carried out from two aspects： the internal cooling system and the outside cooling system. Then, the circuit of UPFC water cooling system is built by analogy method, which makes the structure and each module clear. In the end, the comparison between series water load and parallel water load is presented, and the problem of uneven distribution of parallel channels is discussed.
