Abstract

A synchronization accuracy monitoring system of a time synchronization device for electric power equipment, including a central monitoring system, a network management system, and a measuring device. The measuring device is set in a substation and connected to the main clock device, extended clock device, and time-serving device in the substation; The device obtains the time signal of the master clock device in the substation where it is located, converts it into a PTP message encapsulated with E1, and transmits it to the central monitoring system through the E1 channel of the inter-station SDH. The time signal of the clock, compare the time of the main clock of the substation with its own current time, obtain the first time difference and transmit it to the network management system; the measuring device determines the time of the main clock device and the time of the extended clock device in the substation, the second time difference between the times of the timed devices, and transmit the second time difference to the network management system. The solution of the invention can grasp the output accuracy of the time synchronization device in time.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a synchronization accuracy monitoring system of a time synchronization device for electric equipment. Background technique [0002] There are a large number of equipment in substations of various levels of electric power that require time synchronization devices for accurate timing, such as safety automatic devices, electric energy collection devices, line traveling wave fault location devices, synchrophasor measurement devices, fault recorders, etc. Therefore, time synchronization devices are of great significance to the normal and reliable operation of substations and power grids. However, after the time synchronization device runs for a long time, due to factors such as device aging and program stability, the time synchronization device will appear out of sync, which will affect the normal operation of the device, resulting in inaccurate timing or equipment failure. [0003] In ...
