At present, some studies have been done to evaluate the reliability of the relay protection system in intelligent substation, but all of them ignored a fact that the intelligent substation can effectively utilize redundant information to identify fault components and enhance the reliability of protection, which leads to underestimation of the system reliability. In view of the above problem, this paper presents a new method. Firstly, the architecture of protection system and the reliability of component in intelligent substation is analyzed. Then the effect of information redundancy and data exchange on the reliability of different types of protection is considered in the form of virtual branch. Finally, an example is given to verify the effectiveness of the proposed method.
