Reactive Power Compensation System Based on Wireless Communication

Abstract

The present invention provides a reactive power compensation system based on wireless communication, which includes a reactive power compensation cabinet and a background monitoring server that wirelessly communicates with the reactive power compensation cabinet. The reactive power compensation cabinet includes: a cabinet body, and A control host and a control device, the control host and the control device include: a single-chip microcomputer control host, a data acquisition input module and a data output controller, and the single-chip control host includes: a first processing unit, a first power supply module and a first wireless communication module, the data output controller includes: a second processing unit, a second wireless communication module, a second power supply module, a first electronic switch and a first power capacitor, and the single-chip control host passes through the first and second wireless communication modules Establish a wireless communication connection with the data output controller. The invention avoids the complicated wiring in the reactive power compensation cabinet, has strong communication anti-interference ability, good communication effect, and avoids misoperation of the data output controller.

Description

technical field [0001] The invention relates to the field of power distribution equipment, in particular to a reactive power compensation system based on wireless communication. Background technique [0002] Power quality is an index to evaluate the operation of power system, and the stability of voltage is particularly important. In the operation of the power system, it is necessary to ensure that the bus voltage of each transmission and distribution line is stable within the allowable deviation range. At present, the allowable voltage variation range stipulated by most countries is generally +5%~-10%. [0003] Whether the voltage is stable or not mainly depends on the balance of reactive power in the system. If the reactive power demand of electric loads fluctuates greatly, such as rectifiers, inverters, frequency conversion devices, electronic switching power supplies, electric arc furnaces, large motors and large pumping stations, etc., the line voltage will exceed the ...

AI Technical Summary

Problems solved by technology

Then use the traditional wired communication method (RS232, RS485 and other communication methods) to connect, and the wiring in the limited space of the reactive power compensation cabinet is very cumbersome, and the anti-interference ability is poor

Communication lines and power lines are often tied together, and communication lines are susceptible to electromagnetic interference from strong power lines, which will lead to misoperation of data output controllers or poor information communication
