Abstract

The invention discloses a Beidou GPS-based time synchronization system verification device and method, which overcome the problem of low defect elimination success rate of a transformer substation time synchronization system caused by no synchronous clock source equipment in the prior art, and comprises a Beidou GPS positioning time service module, a B code receiving, transmitting and photoelectric conversion module, a liquid crystal display module and a lithium battery charging and boosting power supply module.The four modules are connected with one another. Beidou GPS time service performance testing, time synchronization input signal verification testing, time synchronization signal output testing, time service success rate calculation and verification success rate calculation are carried out, the time service success rate reaches 100%, the time service performance is excellent, and the requirement for the time service performance of a transformer substation can be met, and the defect elimination success rate is obviously improved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a time synchronization system verification device and method based on Beidou GPS. Background technique [0002] The power grid system is a time-related system. For the systematic analysis of power grid operation and accidents, circuit breakers, protection device actions, and time sequences of various events are required. A substation timing system that provides time sequences is essential. At present, there are 135 substations under the jurisdiction of State Grid Huzhou Power Supply Company, including 22 220kV substations, 91 110kV substations, and 22 35kV substations. Each substation is equipped with a substation timing system. [0003] The substation time synchronization system is very important. It performs time synchronization for equipment such as fault recorders, relay protection devices, measurement and control devices, and background monitoring systems, so that they c...
