Application of real-time Ethernet EPL in intelligent substation
Lei Yan · Power System Protection and Control · 2013
Intelligent substation uses switched Ethernet to share data. In spite of simplicity and efficiency, it can’t promise timeliness. This paper introduces Ethernet POWERLINK (EPL) to improve the timeliness in substation. After analyzing EPL’s principle and protocol structure, EPL is transplanted using BF536 and μCOS real-time operating system. On this basis, this paper combines the data attribute in substation, introduces a solution which shows how to apply EPL in substation. Besides this, a comprehensive testing is carried out to explore the performance of the solution mentioned above. The test demonstrates the feasibility and provides a reference for its future application.
