摘要
分析了几种电能质量干扰发生装置的模型,针对其中的不足之处,提出了一种基于电力电子技术的电能质量干扰源方案。采用DSP控制器,并以15 k VA容量为例对加入干扰源的配电网动模系统进行了仿真分析。仿真结果表明,加入干扰源的动模系统可以模拟多种电能质量干扰环境,并且可用于大功率场合,运行经济,效益较好,较好的满足了对电能质量控制治理设备测试的有效性和实用性要求。
Firstly, the models of several power quality disturbance generators are analyzed. In view of the deficiency, a scheme of power quality disturbance source based on power electronic technology is proposed. Using DSP controller and taking the 15 kVA capacity as an example, connected to the dynamic simulation system of the power distribution network is simulated and analyzed. Simulation results show that the dynamic simulation system with interference source can simulate lots of kinds of power quality disturbance environment, which can be used in high power applications. And the operation is economical, better efficient, better to meet the power quality control equipment testing of the effectiveness and practicality of the requirements.
