10KV wireless communication distribution network microcomputer protection device

Abstract

The invention discloses a 10KV wireless communication distribution network microcomputer protection device. The 10KV wireless communication distribution network microcomputer protection device comprises distribution network terminal devices, and a distribution network communication device and a client side which are connected with the distribution network terminal device through RS485, wherein the client side comprises a distribution network communication device information receiving center and a client side mobile phone, the distribution network communication device adopts a circulation interrogation reply mode for remote monitoring, and obtains remote signaling amount and remote measuring amount of at least five sets of the distribution network terminal devices in a switching station, the distribution network communication device uploads the remote signaling amount and the remote measuring amount of the distribution network terminal devices in a 10KV switching station to the client side through a GPRS (general packet radio service) wireless network, a very high frequency (VHF) radio station of 230MHZ and a short message mode, the radio station is used as a standby communication channel of each distribution network terminal device, and a hot standby dual channel is used in a communication system. The 10KV wireless communication distribution network microcomputer protection device can solve the problem that due to the fact that a remote terminal device of an existing power distribution automation system is a direct current storage battery which is not maintained in deep discharge mode for a long time, performance of the storage battery can rapidly decline with the passage of time, and therefore achieves real time monitoring for capacity of the storage battery.

Description

Technical field [0001] The present invention relates to the technical field of power grids, and more specifically, 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 wiring and operation methods must be continuously optimized according to the demand for electricity. The establishment of the distribution network lays a good foundation for improving the safety and reliability of power supply. At present, although most 10kV distribution network switch stations have the conditions for dual power supply, the protection devices in the station are still in the stage of mutual cooperation based on automatic switch equipment, and reliable information exchange channels and independent on-site protection equipment have not been established. Although there are automation devices for power distribution network equipm...
