| 摘要: |
| 传统电能质量扰动试验系统不能直观反应实际电网扰动，也不能用于测试实际电网扰动下并网设备的运行特性。对此提出一种10 kV/3 MVA数字物理混合仿真扰动试验系统设计方法。该方法能够在实验室环境下实现电力系统运行模拟，可用于电网故障下并网设备的特性研究；同时本扰动试验系统也能模拟基于波形特征描述的电能质量问题。提出了数字物理混合扰动试验系统的总体框架，功率接口为级联H桥式背靠背拓扑，在逆变侧采用比例+重复控制模拟数字侧仿真波形，仿真结果证明所提出的设计方案的可行性。 |

| Abstract: |
| The traditional power quality disturbance test system can neither directly reflect the actual power grid disturbance, nor can be used to test the operation characteristics of grid-connected equipment in the case of the actual grid disturbance. In this paper, a design method of 10 kV/3 MVA digital-physical hybrid simulation disturbance test system is proposed, which can be used to simulate the operation of power system in laboratory environment and study the characteristics of grid-connected equipment under grid fault. At the same time, the disturbance test system can also simulate the power quality problem based on waveform feature description. In this paper, the general framework of the digital-physical hybrid disturbance test system is presented. The power interface is a cascaded H-bridge back-to-back topology. To analogize digital side simulation waveform output, the inverter is controlled by proportional control and repetitive control in output sides. The simulation results show the feasibility of the proposed design scheme. This work is supported by National Natural Science Foundation of China (No. 51277137). |
