摘要
灵绍和昭沂特高压直流输电工程投运后,宁夏电网将成为我国又一高比例风火打捆外送直流送端电网。为了准确分析交直流间相互作用以及直流受端扰动对送端的影响,在ADPSS软件中建立了宁夏电网多直流系统的机电-电磁混合仿真模型,包括西北电网机电暂态仿真模型和宁夏电网三回直流的详细电磁暂态模型。针对送受端电网不同故障类型,评估了混合仿真和纯机电暂态仿真方法下电网受扰响应行为的差异,研究结论对于电网分析计算和制定安全稳定控制措施时选择适用的工具具有参考意义。
After the commission of Lingshao and Zhaoyi high voltage direct current （HVDC） transmission project, Ningxia power grid will become another high proportion wind -fire banding sending grid. In order to accurately analyze the interaction between AC and DC and the influence of receiving end disturbance on sending end, an electromagnetic -electromechanical hybrid simulation model of Ningxia muhi -HVDC system is established on ADPSS software including electromechanical transient simulation model of northwest power grid and the detailed electromagnetic transient model of three HVDC systems in Ningxia power grid. For the different fault types of the power grid at the sending and receiving end, the differences of the disturbed response behaviors under hybrid simulation and electromechanical transient simulation are evaluated. The research conclusion owns reference significance to the selection of suitable tools for power grid analysis and calculation and the formulation of stability control measures.
