摘要
针对全球互联电网建模的一些基本问题以及建模仿真对系统数据的需求进行分析,提出一种用于稳态潮流分析的基本建模方法。同时分析由故障引起的暂态稳定性、低电压穿越能力和动态特性等问题。研究表明,因为仿真能力和研究系统的限制,全球能源互联电力系统建模最基本的方法仍然是网络等值和实时数模混合仿真。全球互联电网,尤其是含有高压直流输电系统的互联系统的建模仿真对高性能仿真实验室的建设提出新的需求。
Problems and data requirements of the global energy interconnection(GEI) based power system modeling are analyzed. A generalized analytical model of the GEI based power system modeling for the steady-state load flow analysis is presented. The key issues of transient stability, low voltage ride-through capability and dynamic performance of the global energy interconnection based power system caused by the faults are addressed. Studies show that due to limitations of simulation capabilities and investigated systems, the network reduction and the real-time digital-analogue hybrid simulations are fundamental and essential for the global energy interconnection based power system modeling. To fulfill the requirements of the GEI based power system modeling, particularly that with high voltage direct current(HVDC) technologies, high-performance simulation labs have to be established and used thoroughly.
