摘　　要：电力系统跨区联网在某些弱联系运行方式下容易诱发区域间低频振荡现象。通过挖掘多直流系统的控制敏感点,设计了直流附加阻尼控制器,并提出基于Matlab-Simulink环境的新型样机测试模式,完成了控制逻辑编辑,制作了实际的控制样机。搭建了Hypersim全电磁暂态实时仿真试验平台,通过仿真优化了直流附加阻尼控制器参数。利用华中—华北电网模型完成了直流附加控制器抑制区域间低频振荡有效性试验验证。It is easy to induce interregional low frequency oscillation in the interconnected network of power system under some weak link operation modes.In this paper,the control sensitivity of the multi DC system is judged.And the DC additional damping controller is designed.A new prototype testing model based on the matlab-simulink environment is proposed.The control logic compilation is completed and the actual control prototype is made.The Hypersim full electromagnetic transient simulation test platform is built,and the parameters of the DC additional damping controller are optimized by simulation.The validity of the DC additional controller is verified by the North-Central China powergridmodel.
