风场柔直互联系统次/超同步交互失稳机理分析及其阻抗优化控制方法
Sub/Super-synchronous Stability Analysis and Impedance Optimization Method of Wind Farms With MMC-HVDC Systems
摘要
Abstract
Sub/Super-synchronous oscillation phenomena may occur in a modular multi-level converter-based high-voltage direct current(MMC-HVDC)transmission system due to the complex control coupling between the wind farm and the MMC.In order to reveal the interaction between the control loops of the wind farm and the MMC converter station,and to clarify the interaction mechanism and design constraints of the control loops of the VSC-HVDC transmission system for the wind farm.Firstly,the MMC-HVDC sequence impedance model is established.Next,the matching relationship between the wind farm and the MMC-HVDC control loop is investigated,and the results indicate a significant stability boundary exists between the bandwidths of the MMC voltage loop and the wind farm phase-locked loop.On this basis,the explicit mathematical relationship between controller parameter interaction and the Nyquist stability determination equation is analyzed,and the coupling influence law and parameter design boundary of the control loop of the VSC-HVDC transmission system for the wind farm in the sub/super-synchronous frequency band are clarified.On this basis,an impedance remodeling control strategy based on the MMC converter station is proposed.It completely decouples the wind farm and MMC converter station,expands the range of control parameters,and improves the stability of the interactive system.Finally,the theoretical analysis and experimental verification of the impedance reshaping method are completed on RT-LAB control hardware-in-the-loop platform.关键词
