摘要: |
完成了一种微电网数字物理混合仿真平台的设计与实现。平台结构采用NI-PXI数字平台与DC/AC换流器物理平台分层设计方法,控制方式采用底层归一化控制与上层并行控制方法,利用NI VeriStand完成微电网Matlab/Simulink控制模型的实时仿真。结合实验平台物理结构与控制方式设计,提出了微电网主从模式无缝切换、对等模式的黑启动以及分层模式的频率二级调整对应的控制策略。在国家能源大型风电并网系统研发(实验)中心完成平台搭建,开展微电网多控制模式数模混合仿真实验,实验结果验证了控制策略的有效性及试验平台设计方案的科学性。 |

Abstract: |
A digital/physical hybrid simulation platform for micro-grid is designed and implemented. The platform is composed of NI-PXI digital platform and DC/AC physical platform, the control mode is composed of bottom normalized control and upper layer parallel control, and the Matlab/Simulink control mode of micro-grid is converted to the real-time simulation mode by the NI VeriStand. The micro-grid control mode includes master slave control, peer-to-peer control and hierarchical control modes. The control strategy of key operation mode corresponding to the three kinds of control mode is proposed based on the structure and control mode of the platform. The simulation platform is established in National Wind Power Grid Integration R & D (Testing) Center and the control strategy of micro-grid is verified on the platform. Experimental results demonstrate the effectiveness of the control strategy and the scientificity of the design scheme. |
