基于P89V51RD2的电力监测分相动态无功补偿控制器

Phase-splitting Reactive-power and Dynamic-compensation Controller Based on P89V51RD2 Microcontroller

提出了一种新型的分相动态无功补偿控制器。该控制器以P89V51RD2单片机为控制核心,用电能计量芯片ATT7022B采集电网的电能参数,采用混合补偿的方式控制电容器组的投切,实现对电网运行参数的实时监控,保证电网的安全运行。该装置响应快、控制精确、可靠性高,是一种较理想的低压电网无功补偿装置。

A new kind of reactive-power and dynamic-compensation controller is proposed. In order to realize the real-time monitoring for power grid safity, the P89V51RD2 singlechip isused as the core of the controller,ATT7022B IC is used for the electric power parameters collection;and the switch of the capacitors is based on hybrid compensation method. The controller which is an ideal low voltage reactive power compensation device has the characters of rapid response, high-precision and high reliability.
