| 摘要: |
| 提出了基于通用功率变换器的交直流混合配电网系统架构概念，在解决传统交流配电网电能质量问题同时，满足直流配电网发展需求。首先提出了一种结合电压平衡控制器(VBC)和四桥臂型三相四线制电压源变换器(VBC)的新型UPC整体系统结构，并给出一种基于交流电流跟踪补偿的并网VSC和基于恒定直流电流脉冲触发模式的VBC整体协调控制策略。最后通过搭建75 kW仿真实验系统验证了UPC在直流配电、分布式电源直流并网和交流配电网电能质量治理等方面性能的有效性。 |

| Abstract: |
| The concept of universal power converter (UPC) based hybrid AC and DC distribution system architecture is proposed, which can solve the traditional AC distribution power quality problems and satisfy the demand of DC distribution development. First, a novel UPC system structure combining the voltage balancing controller (VBC) with the four-leg based three-phase four-wire voltage source converter (VSC) is adopted, using the overall coordination control scheme of the AC current tracking compensation based grid-interfaced VSC and the constant DC current burst mode based VBC. In the end, the 75 kW simulation experimental system is designed and tested to verify the performance of the proposed UPC under DC distribution and distributed DC sources conditions, as well as the power quality management of AC distribution. |
