摘　　要：研究拓扑分区并行下的直流配电网暂态电压稳定控制模型,保障直流配电网的稳定运行。将直流配电网结构变为抽象的广义节点网络,基于广义节点之间的拓扑结构实现直流配电网的分区;通过柔性直流互联各个分区,使各个分区之间的频率都保持在额定频率范围内,实现每个分区之间的异步互联;通过引入各个分区的直流配电网暂态电压的变化量,改变下垂系数以提高配电网的阻尼,增强暂态电压的稳定性,实现拓扑分区并行下的直流配电网暂态电压稳定控制。实验结果表明,该模型能够完成各分区的合作互济,实现直流配电网分区之间暂态电压的同步运行,增强直流配电网暂态电压的稳定性。generalized node network,and the partition of the DC distribution network is realized based on the topological structure among the generalized nodes.Each partition is interconnected flexible DC,the frequency between each partition is kept within the rated frequency range,and asynchronous interconnection between each partition is realized.By introducing the variation of the transient voltage of DC distribution network in each partition,the droop coefficient is changed to improve the damping of the distribution network,enhance the stability of the transient voltage,and realize the transient voltage stability control of DC distribution network under the topology partition parallel.The experiment results show that the model can complete the cooperation and mutual assistance of each partition,realize the synchronous operation of the transient voltage between the partition of DC distribution network,and enhance the stability of the transient voltage of DC distribution network.
