| 摘 要： | 针对应用于交直流配电网的电力电子变压器,根据孤岛模式下配电网的运行特性,提出了一种应用于孤岛模式的自治运行控制策略,通过建立全局化的多端口传输模型,统一各端口的运行状态,协调各端口的能量交换,充分发挥电力电子变压器各个端口能量互通、相互支撑的优势,实现配电网的自治运行。搭建了含电力电子变压器的交直流配电网仿真系统,验证了控制策略的有效性。

| Abstract: | According to the operating characteristics of distribution network in the islanded mode, an autonomous operation control strategy applied to the islanded mode is proposed for the power electronic transformer(PET)applied to the AC/DC distribution network. By establishing a globalized multi-port transmission model, the operation status of each port is unified and the energy exchange of each port is coordinated to give full play to the energy exchange and support of each port, and achieve the autonomous operation of PET. The simulation system of AC/DC distribution network with PET is built and the effectiveness of the control strategy is verified. |
