新型电能质量干扰源的研究

Research on the new-style power quality disturbance source

介绍了两种传统类型的电能质量干扰源。就其不足之处,提出了一种新型的电能质量干扰源设计方案。该干扰源采用了DSP技术和双环控制方法,实现逆变器干扰量的快速准确输出控制,可以实现大容量输出。对该方案进行了仿真和实验研究,结果表明,此干扰源可以产生多种对称或不对称的波形畸变、电压跌落等电能质量干扰,并且结构简单易实现,从而验证了该干扰源的有效性。

This paper introduces two types of the traditional disturbance source. Compared with their deficiencies, a new-style power quality disturbance source that adopts the DSP technology and double loop control strategy, is presented. MATLAB simulation and test results show that the new-style power quality disturbance source can generate many types of power quality disturbance, such as symmetry or asymmetry abnormal waveform and voltage sags, etc. And the simple structure is easily realized, whieh verify its validity.
