Abstract

The invention relates to a precision monitoring system for time synchronization of power equipment, which comprises a monitoring center formed by a central control system and a network management system and a time measuring device arranged in a substation, and is characterized in that the time measuring device is arranged in a substation and connected with a master clock module, an extended clock module and a time-served module in the substation; the time measuring device acquires a time signal of the master clock module in the substation, converts the time signal into a PTP (Precision Time Protocol) packet packaged by E1, and transmits the PTP packet to the central control system through an E1 channel of an inter-station synchronization digital system. The scheme provided by the invention can master the output precision of a time synchronization device timely. The precision monitoring system can perform monitoring on the synchronization precision of various different time synchronization devices, and can master the operating state of the time synchronization devices timely, thereby being conducive to processing a fault timely.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an accuracy monitoring system for time synchronization of electric equipment. Background technique [0002] Electricity is an important secondary energy source, and its operation and dispatching are closely related to the national economy and the people's livelihood. The sustainable development of the power grid industry must be based on customers. In this way, high-quality services are determined, and it is the responsibility of the power region. An important way to ensure sustainable economic development. In substations of various levels of electric power, there are a large number of equipment that require accurate timing of time synchronization devices, such as safety automatic devices, electric energy collection devices, line traveling wave fault location devices, synchronized phasor time measurement devices, fault recorders, etc. . Therefore, time synchronization devices are ...
