摘要
电力系统的巨大发展给仿真技术带来新的挑战,传统的仿真手段已不能满足实际大规模互联系统分析的要求。专家、学者结合电磁、机电暂态仿真的优点提出了混合仿真的技术路线。文中综述了国内外混合仿真技术的研究、发展情况,明确了混合仿真的2个基本要求以及现阶段面临的实质难题,包括分网方案制定、单侧计算时边界条件和对侧等值、故障时刻交互时序等;提出了预测校正的思路,阐明了其可行性,展望了混合仿真技术的发展方向。
The tremendous developments of power systems bring new challenge to the simulation technology and conventional transient simulation cannot meet the analytical needs of practical large-scale power systems.Combining the advantages of electromagnetic and electromechanical transient simulations, experts and scholars have proposed the hybrid simulation technology.This paper gives an overview on the research and development of the hybrid simulation at home and abroad.Then two fundamental requirements for engineering applications are specified and several essential difficulties are described,including the system segmentation scheme,the boundary condition for the calculation of one side and equivalence of the other side,and the interactive order of two sides during the system fault.Based on the analysis of these difficulties,a forecast and correction method is proposed,with its feasibility expounded.Finally,the paper makes a simple comment on the development trends of the hybrid simulation.
