A test method for time synchronization function and punctuality performance of distribution automation system

Abstract

The invention provides a method of testing a distribution automation system time setting function and time keeping performance. The method comprises the following steps: equipment information is configured; a testing main station time setting function is tested; an interference time setting function is tested; an SNTP time setting function is tested; and the time keeping performance is tested. The method of testing the distribution automation system time setting function and the time keeping performance makes up the missing of a distribution automation system time setting function and performance testing method, solves the problem that direct and accurate acquisition of the distribution automation equipment time is difficult, and the acquired time precision can not meet testing requirements, effectively avoids human factor influences during the testing process, and enables the testing time precision for the time setting function and the time keeping performance to reach a microsecond level. The testing method provided by the invention enables the testing on the time setting function and the time keeping performance of the distribution automation system to be standardized and specialized, the time setting function and the time keeping performance before the distribution automation equipment is accessed to the distribution network can be ensured to meet requirements, and the stability and the reliability of safety operation of the distribution network can be ensured.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the time setting function and punctuality performance of a power distribution automation system. Background technique [0002] The safe and stable operation of the distribution network requires distribution automation equipment to operate based on a unified time reference to meet the time consistency requirements for sequence of events (SOE), fault recording, and real-time data acquisition, ensuring distribution network operation monitoring, fault diagnosis, The accuracy of parameter verification ensures the efficiency and reliability of distribution network accident analysis and stability control. Among them, the time synchronization function and punctual performance are important performance indicators of the time synchronization of automation equipment. Due to the suddenness, randomness and uncertainty of distribution network faults, when a fault occurs in the distribution s...
