Impedance Modeling and Stability Analysis of MMC-based HVDC for Offshore Wind Farms
基于模块化多电平换流器(modular multilevel converter，MMC)的柔性直流输电技术(MMC-HVDC)已成为大规模、远距离海上风电场并网的理想解决方案。但是由于MMC自身结构特点，当MMC-HVDC接入风电场时有可能发生振荡或不稳定现象。该文建立MMC的交流侧小信号阻抗模型，根据最小阻抗环增益的奈奎斯特(Nyquist)稳定性判据判断互联系统的稳定性，并预测系统潜在的谐振频率及稳定裕度。研究结果表明，适当的环流控制能够显…查看全部>>
Modular multilevel converter-based high- voltage DC transmission (MMC-HVDC) technology has become an ideal solution for grid integration of large and remote offshore wind farms. However, due to the characteristics of MMC topology, oscillation or instability phenomena might occur in wind farms integrated through MMC-HVDC systems. AC-side small-signal impedance models of the three-phase MMC were first developed in this paper. The impedance-based Nyquist stabil…查看全部>>
