基于瞬时无功功率理论的动态无功补偿控制装置

The Dynamic Reactive Power Compensate Controller Based on Instantaneous Reactive Power Theory

在要求对快速变化的负载进行跟踪动态补偿的情况下,建立在平均值基础上的传统功率理论已经难以适用。本文选用了基于dq变换的运算方式作为实时无功功率检测方法,采用数字信号处理器对算法在装置上进行了实现,现场应用情况达到了预期效果。

In the circs of reactive power compensate for rapid fluctuate load, the traditional reactive power measurement theory based on the equilibration is not applicable. In this article we use the arithmetic based on dq trans for reactive power measurement, which achieved in the Digital Signal Processor （DSP） of the device. The results of field application reached the expected effects.
