摘　　要：研究了一种指定谐波电流注入装置控制策略,作为模拟谐波源来测试谐波源定位装置的性能。其采用了基于电网电压定向的矢量控制策略,对电压环和电流环进行了有效的调节。从谐波电流给定以及控制方法两方面对谐波注入问题进行了定量的研究。利用坐标变换技术使得谐振控制器的数量减半,节省了CPU的资源。测试不同参数下谐振控制器的性能,选择了最优性能的谐振控制器。仿真和实验结果验证了该调制策略的可行性与有效性,实现了多种指定谐波的组合输出,为谐波源定位方法提供了便利。This paper studied a control strategy for a designated harmonic current injection device as a simulated harmonic source to test the performance of the harmonic source positioning device.It used the control strategy of grid voltage vector orientation to adjust the voltage loop and current loop.This paper did qualitative research from the assigned harmonic current and the control method to discuss the problem of current harmonics injection.The coordinate conversion technique has been used to cut the number of resonant controllers;the CPU resource has been saved.Moreover,it tested the performance of the resonant controller and chose the optimal one.The experimental results verify the feasibility and effectiveness of the modulation strategy and realize the combined output of various specified harmonics.It also provides convenience to the method of the harmonic source location.
