A system for detecting time quality of electric power substation

Abstract

A system for detecting time quality of electric power substation the system uses PTN equipment to replace the traditional SDH optical transmission equipment, B out-of-code time signal of the B out-of-code time detection module of the substation is monitored by the PTN equipment of the substation, compared to 1588 packets carrying time information transmitted from the master station wired PTN communication network, the time deviation between the time information of the main station from the main station of the power supply bureau and the time signal outside the B code of the local substation iscalculated, which is sent to the power supply bureaus at all levels and presented graphically on the network management. The problem of monitoring the time quality of the clock source in the substation is solved.

Description

technical field [0001] The invention relates to the field of time quality detection of power systems, in particular to a time quality detection system of a power substation. Background technique [0002] At present, in the 220kV and above substations in the power system, the clock source BITS generally uses the optical port B code. Generally, two main and standby BITS clocks are deployed, and each BITS is connected to two satellite clock sources. BITS passes through multiple external time optical port B Code docking station power equipment, mainly used for power fault location analysis and maintenance. There are many existing BITS manufacturers in the market, most of which are small factories, with different performances in clock performance, quality, and maintainability. It is difficult to realize effective monitoring and management of BITS produced by many manufacturers, and each BITS manufacturer has many network management versions and only a limited topology.

Problems solved by technology

There are many existing BITS manufacturers in the market, most of which are small factories, with different clock performance, quality, and maintainability. It is difficult to realize effective monitoring and management of BITS produced by many manufacturers, and each BITS manufacturer has many network management versions and only a limited topology. Demonstration ability, no clock performance monitoring function, single source of clock source, only one way to import from the sky, therefore, there is currently no better solution to realize the time quality detection of BITS at many stations in 220kV and above substations in the power system
