Key technologies and test method of Remote Terminal in intelligent distribution automation system

Around the distribution automation reliability, real-time, safety, operability and maintenance of the basic requirements, a detailed analysis of the five areas, such as structure and safety design, function, performance, electrical and magnetic properties and the main station communications etc, are putted forward to explain the key technologies of intelligent distribution automation terminal. The paper also bring forward a set of effective and practical testing techniques on the system and the targeted building blocks, mainly including the main fault simulation testing, signal avalanche testing, remote mutation testing, measure data change testing, electrical and magnetic properties testing and master site communications testing technologies. Through practical application Experience, it was showed that this test technology could finish the whole system test or the functional modules test of system and find the defects in each functional module to Enhance the construction, inspection, testing and maintenance levels of distribution automation system in the future.
