中文摘要

针对二极管整流器(DR)型高压直流输电的海上风电场,传统分布式控制存在有功与无功功率强耦合问题,导致暂态下风机变流器功率、电压及频率波动。本文提出一种基于新型自适应虚拟阻抗的解耦分布式控制策略,有效抑制了暂态振荡,提升了系统稳定性。

English Abstract

In offshore wind farms connected via diode-rectifier-based high-voltage dc, conventional distributed control strategies have significant coupling among active and reactive power, leading to large oscillations in wind turbine (WT) converter power, voltage, and grid frequency during transients. In this work, we propose a decoupled distributed control strategy based on a novel adaptive virtual impeda...
