Study on the Distribution Automation System Terminal Automatic Test Method

Abstract

With the widespread use of DAS, higher requirements for distribution automation terminal on-site testing have been put forward on account of limitations of field working conditions. Based on the requirement of relevant standards, this paper discusses automatic testing exploratory research, by analyzing the principal experimental objects and information transmission mode of the distribution automation terminal, which adopts IEC-60870-5-104 protocol. On this basis, this paper brings forward a set of feasible distribution automation terminal test method based on automatic information acquisition and predefined rules, by scheme design, process design, and building test environment. Finally, based on the test environment which divides into online and offline modes, the relevant automatic testing system has been studied and applied, achieves a fully automated power distribution terminal test process, and improves the efficiency of this test to ensure safe and stable running of power distribution automation terminal.
