ABSTRACT
The article introduces passive power compensator based on AT89C52 controlling with high precision. It measures excess phase of voltage and circuit used digital circuit. The AC solid-state relay of passing zero is applied to the control switch. It is input when the voltage of the power system equals the voltage of the capacitor and elimination when the circuit is zero. A Microcomputer AT98C52 competes the Data process, input, output etc. The practical result shows the advantages of high precision, less influence on low-voltage power system, fast response, connecting capacitors with single-phase and the ability of anti-jamming. It is mainly used to compensate passive power in present factory and mine.
In the power-system, the raise of the power-factor is a important technologic work. It matters the utility and quality of the power-system. The method of power-factor has always been taking seriouslyby people. The research of the high-quality power-factor compensationhas great social and economic meanings.
This article utilizes the AT89C52 monolithic integrated circuit, thelow pressure reactive power carries on the monitor and the control tothe electrical power system in, enables the power factor to achievethe adjustment and the optimization, improved the electrical powersystem power supply quality and the economical movement.
