Wireless remote monitoring system and wireless remote monitoring method for reactive compensation device

Abstract

The invention discloses a wireless remote monitoring system and a wireless remote monitoring method for a reactive compensation device. The system comprises a CAN (controller area network) bus communication circuit and a wireless transceiving module which form a monitoring node of the wireless remote monitoring system. The CAN bus communication circuit comprises a microcontroller and a CAN bus transceiver. The microcontroller acquires data on reactive compensation device nodes and transmits the acquired data to the CAN bus transceiver through an eCAN controller, the wireless transceiving module transmits the data to a sever through GPRS (general packet radio service) and Internet, a database is built at the server for storing and managing data of different nodes, and the sever transmits a actuating signal to the reactive compensation device along the same path through power grid power quality information acquired by the server. The wireless remote monitoring system and the wireless remote monitoring method guarantees data acquisition, data processing, data calculation and data safety, satisfies local monitoring of the reactive compensation device, and realizes remote monitoring.

Description

technical field [0001] The invention relates to an electric power monitoring system and its method, in particular to a wireless remote monitoring system and its method suitable for an automatic reactive power compensation device. Background technique [0002] The reactive power compensation device is the main equipment in the substation and the power industry. It is mainly used to compensate the reactive power of the power system, improve the power reputation of the system, improve the quality of power supply, reduce the reactive power loss of the line, and improve the power transmission capacity of the grid. There are mainly SVC (thyristor switched reactor), SVG (static var generator), TSC (thyristor switched capacitor), and FC. It is mainly used in reactive power compensation and harmonic control in steel, chemical, smelting, and power grid industries. With the continuous increase of high-power nonlinear and impact loads, the application of high-voltage reactive power com...

Problems solved by technology

[0009] In the past, the monitoring system and it were usually developed by text language programming for a specific application object, the user interface was not beautiful, the development cycle was long, and it was difficult to transplant and change

In addition, the functions of the existing monitoring system are relatively simple. Generally, on-site monitoring is used. There is a man-machine interface on the equipment, and the operation information of the equipment is displayed on the man-machine interface. For remote substations, coal mines, metallurgy, etc. very inconvenient place
