| 摘 要： | 基于电力系统分析软件包PSASP,使用其用户自定义功能,建立了详细的无功功率控制模型。该模型为用户自定义高压直流输电模型的一部分,其参照青藏直流系统,并经适当简化而得。主要包括无功功率发生计算模块、无功功率消耗计算模块、无功功率控制模块及换流站无功功率调节控制模块,给出了每个模块的建模方法及建模原则。最后通过在WEPRI-7七节点系统,仿真验证了无功功率控制用户自定义模型对于交直流系统相互作用及稳定性分析的正确性及必要性。

| Abstract: | A detailed user-defined (UD) reactive power control (RPC) model of the HVDC has been developed in Power System Analysis Software Package (PSASP). The UD RPC model, as one part of the UD HVDC models which have been set up based on the control system of Qinghai-Tibet interconnection project, includes reactive power generation calculation, reactive power consumption calculation, reactive power control strategies, and converter reactive power regulator strategies. Each part of the UD RPC modeling and its guidelines are presented in this paper. Case studies are conducted on the WEPRI-7 system of which embedded HVDC models are replaced by the UD HVDC models. The simulation results show correctness and necessity of the UD RPC model for the AC/DC hybrid system interaction and stability analysis. |
