| 摘要: |
| 针对目前几种电能质量干扰发生装置的模型存在的不足之处，提出了一种基于电力电子技术的电能质量干扰源设计方案。采用DSP控制器、三相PWM有源可控整流和可控逆变控制技术，结合不对称与高谐波条件下的MRF补偿算法，以15 kVA 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，较好地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。 |

| Abstract: |
| Based on the existing shortcomings of current model of several kinds of power quality disturbance device, a scheme of power quality disturbance source based on power electronic technology is proposed. Using DSP controller, active three-phase PWM rectifier and controllable inverter control methods, combining MRF compensation algorithm under the condition of asymmetry and high frequency, and taking the 15 kVA capacity as an example, the dynamic simulation system of power distribution network after adding disturbance source 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 and better efficient, and can meet the effectiveness and practicality requirements on the test of the power quality control equipment.
