| 摘 要： | 为了解决谐波含量大和功率因数低下的电网质量问题,研究设计了一种基于DSP芯片TMS320F28335的集谐波分析与无功补偿功能于一体的高精度、快速补偿装置。根据非正弦周期信号的无功功率理论,实时检测工频周期,并进行同步采样,通过快速傅里叶变换(FFT)运算得到各次谐波及无功功率,使用新型电容器组投切方案进行补偿,实现动态无功补偿。经试验验证,控制器具有良好的补偿功能。

| Abstract: | A new dynamic reactive power compensator was designed to solve the problems of low power factor and big harmonic content based on the TMS320F28335. According to the non-sinusoidal signal＇ s theory of power,it can real-time check the frequency to make sure the synchronous check happen, then get the each part of the harmonic and the reactive power with fast fourier transform （FFT）, quickly to compensate the lost power, realize the dynamic reactive power compensation. It is validated by experiment that this compensator has good ability of compensation. |
