High-accuracy synchronous system detection device applied to intelligent transformer substation

Abstract

The invention provides a high-accuracy synchronous system detection device applied to an intelligent transformer substation. The high-accuracy synchronous system detection device comprises a satellite clock signal receiving unit, a signal receiving and analyzing unit of a synchronizing device, a synchronous/error code signal simulation output unit of the synchronizing device, a synchronous/error code effect feedback detection unit of a synchronized device, and a self-punctuality capacity detection unit of the synchronized device. According to the high-accuracy synchronous system detection device, synchronous signals can be analyzed and counted, by conducting high-accuracy synchronous measurement technology on the synchronous signals, accuracy, stability and integrity of source signals are obtained, the synchronous signals can be simulated and output, synchronous output of the synchronous signals can be adopted, a manually-controllable error code output method can also be adopted, signals which are fed back by the synchronized device after the synchronized device receives synchronous or matched time tick signals can be detected, and therefore a complete chain of a clock synchronous system in the intelligent transformer substation can be comprehensively and scientifically detected.

Description

Technical field [0001] The invention relates to the technical field of clock synchronization of power system intelligent substations, in particular to a high-precision synchronization system detection device applied in intelligent substations. Background technique [0002] Compared with traditional substations, smart substations have higher and stricter requirements for time synchronization networks, but various time synchronization devices on the market are uneven: interface types are not standardized, synchronization time is long, synchronization signal stability is poor, and time-keeping ability Poor, insufficient network load capacity and other problems frequently occur. In addition, when the time synchronization device in the smart substation has abnormalities and failures, there is no unified standard for how various synchronized devices should respond. Therefore, once the time synchronization device fails during operation, the operation of the timed equipment will be affe...

AI Technical Summary

Problems solved by technology

[0002] Compared with traditional substations, smart substations have higher and stricter requirements for time synchronization networks, but various time synchronization devices on the market are uneven: non-standard interface types, long synchronization time, poor synchronization signal stability, and self-timekeeping capabilities Problems such as poor network capacity and insufficient network load capacity frequently occur

In addition, when the time synchronization device in the smart substation is abnormal or faulty, there is no uniform specification on how the various synchronized devices should respond

Therefore, once the time synchronization device fails during operation, the operation of the timed equipment will be affected, and in severe cases, it will cause the entire grid time to be confused and bring losses to the power system
