摘要
通过智能无功补偿控制器系统,采用FFT算法进行功率测量,实现了对所需无功分量进行精确计算,准确跟踪系统无功变化,达到了对系统动态进行无功补偿的目的。控制器投入运行后,提高了功率因数和风机输出有效功率,降低了发电成本,创造了可观的经济效益。
Through intelligent reactive power compensation controller system, the paper adopts FFT algorithm to measure power, achieving accurate calculation of reactive power component needed and tracing accurately the change of the system＇s reactive power and reaching to the purpose of the system＇s dynamic reactive power compensation. After putting into operation, the controller improves power factor and output of effeetive power, reduces the costs of power generation, and creats considerable benefit.
