doi:10.11930/j.issn.1004-9649.201705110

Abstract

Abstract: In order to increase efficiency and improve reliability of protective relaying system testing, an automatic defect locating method for relay protection systematic testing is proposed. Firstly, a data flow model, including port connection, publishing and subscribing models is developed. Based on proposed data flow model, a fault location method is established. In order to verify accuracy of developed models and proposed methods, a simplified protective relaying system is employed to present a case study. The proposed model and method are applied to the case and the fault location results demonstrate the accuracy and efficiency of proposed model and method during protective relaying testing.

Key words: relay protection, testing, whole-view, defect locating
