A 10kv wireless communication distribution network microcomputer protection device

Abstract

The invention discloses a 10kV wireless communication distribution network microcomputer protection device, including: distribution network terminal equipment, a distribution network communication device connected to the distribution network terminal equipment through RS485, and a client, the client includes a distribution network communication device information receiving center and customers Terminal mobile phones, among which, the distribution network communication device adopts a circular question-and-answer method for remote monitoring, and obtains the remote signal volume and telemetry of at least 5 sets of distribution network terminal equipment in the switching station; the distribution network communication device uses GPRS wireless network, 230MHz VHF The radio station and short message upload the remote signaling amount and remote measurement of the distribution network terminal equipment in the 10kV switching station to the client; the distribution network terminal equipment uses the radio station as a backup communication channel, and the communication system adopts a hot backup dual channel. This solution can solve the problem of real-time monitoring of battery capacity because the remote terminal in the existing distribution automation system is equipped with a battery that is DC and has not been maintained in deep discharge for a long time, and its performance will decline rapidly over time.

Description

technical field [0001] The invention relates to the technical field of electric power grid, and more specifically, relates to a 10kV wireless communication distribution network microcomputer protection device. Background technique [0002] With the rapid development of the national economy, the scale of the power grid is expanding day by day, and the connection mode and operation mode must be continuously optimized according to the power demand. The establishment of the power distribution network lays a good foundation for improving the safety and reliability of power supply. At present, although most of the 10kV distribution network switch stations have the conditions for dual power supply, the protection devices in the stations are still in the stage of mutual cooperation based on automatic switchgear, and no reliable information exchange channel and independent on-site protection equipment have been established. Although there is an automation device for power distributio...
