摘要
采用改进的扇合矢量变换法,从三相不对称且含谐波的系统中提取基波的负序电压及电流。介绍了无附加滞后的扇合矢量变换法,以TMS320F2812芯片为控制系统的核心进行了有源电力滤波器硬件设计,给出了软件设计的主程序流程图。运用DSP实现扇合矢量变换法,算法简单,有很好的应用前景。
Negative sequence voltage and current of fundamental waves were taken from three-phase asymmetric system with harmonic waves by means of the improved fan-in vector transfer. Introduction was made to the fan-in transfer method without additional delay. Hardware of active power filter with TMS320F2812 as the core was designed, main flowchart of the software given. The algorithm with DSP realizing fan-in vector transfer is simple, having very good application perspective.
