System for inspecting uplink communication of plant-station terminal

Abstract

The invention discloses a system for inspecting uplink communication of a plant-station terminal, which includes plant-station electric energy meters, a plant-station terminal, a plant-station terminal uplink communication investigation device, a measurement automation master station, an integrated communication test module, a special power line, and a special power network. The plant-station electric energy meters are connected with the measurement automation master station through the plant-station terminal. The plant-station terminal is in communication connection with the measurement automation master station through the special power network. The plant-station terminal transmits collected electric energy data to the measurement automation master station through the special power line. The integrated communication test module connects the plant-station terminal uplink communication investigation device with the special power network and the special power line. Through the technical scheme of the invention, the inspection steps are simplified, the inspection method is optimized, the fault points of the communication and the channels are located accurately, and the level and work efficiency of field operation and maintenance are improved.

Description

technical field [0001] The invention relates to the field of troubleshooting of power grids, in particular to a system for troubleshooting uplink communications of plant and station terminals. Background technique [0002] The power station terminal is responsible for the collection of electric energy data of all electric energy meters in substations and power plants, and is an important part of the metering automation system. There are various transmission media for the uplink communication between the plant station terminal and the metering automation master station, such as power private network (Ethernet), power line, optical fiber, telephone dialing, etc. [0003] At present, the troubleshooting of uplink communication faults generally adopts the elimination method of step-by-step inspection, which requires the cooperation of the equipment side of the communication room and the substation site, and generally requires the cooperation of multiple people. [0004] In addi...

Problems solved by technology

[0003] At present, the troubleshooting of uplink communication faults generally adopts the elimination method of step-by-step inspection, which needs to cooperate with the equipment side of the communication room and the substation site to troubleshoot, and generally requires the cooperation of multiple people.

[0004] In addition, if the communication parameters of the factory station are set incorrectly, it will also lead to the failure of normal communication with the master station, and the operation interface and maintenance software of each manufacturer's terminal are not uniform, and the operation is cumbersome. At present, most of them are manually set on site. low efficiency
