基于电压源换流器的高压直流输电系统多尺度暂态建模与仿真研究
Multi-scale Modeling and Simulation of Diverse Transients inVSC-HVDC Transmission Systems
摘要
Abstract
Multi-scale modeling for accurate, fast and flexible simulation of electromagnetic and electromechanical transients in voltage source converter-based high voltage direct current (VSC-HVDC) transmission systems was presented and validated. It makes use of the methodologies such as shifted frequency analysis (SFA). A novel analytical relationship between the shifted frequency (SF)-domain and dq-domain was derived leading to a system-level SFA-based VSC model. Additionally, a multi-scale model of DC transmission lines was developed with selective insertion of a π-segment. By adjusting the simulation parameters such as time-step size, diverse transients with multiple time-scales and in different network-positions can be simulated. Simulation results are carried out on two-terminal and five-terminal VSC-HVDC transmission systems. It is proved that high-frequency transients are simulated accurately, and slow-changing transients are modulated with the computational costs reduced significantly. In addition, the flexibility of hybrid simulation of the electromagnetic and electromechanical transients in VSC-HVDC systems is improved.关键词
