目前直流输电工程的直流保护冗余配置一般采用”三取二”方式,但在工程实际中有不同实现方法.论述了”三取二”逻辑的原理特点及其优越性,并从逻辑功能以及实现策略的角度,介绍其在几个直流输电工程中的具体应用.针对直流工程中控制保护逻辑提出了改进建议,可供未来的直流输电工程建设参考.

The “two out of three” logic is currently used in the DC protection redundant configuration of HVDC projects, but there are different implementation methods in engineering practice. This paper discusses the principle and advantage of the logic, and introduces its applications in several HVDC projects in terms of logic function and implementation strategy. Certain suggestions are put forward for improving the control protection logic of HVDC projects as to be reference for the future one.
