摘要

构网型风电机组在弱电网中具有良好的性能表现,可为电网提供频率、电压支撑,但高比例电力电子设备接入会导致电网谐波污染,新能源机群故障穿越失败也会对电网产生暂态冲击,恶化电能质量。针对上述问题,该文采用基于九开关变换器的统一电能质量调节器实现谐波治理和源网故障隔离,大大降低变流器电流越限风险。为对多台风电机组并联产生的环流进行抑制,并提升构网型风电机组故障穿越期间主动支撑强度,对虚拟同步机功率耦合机理及暂态功角稳定性展开分析,基于无功环附加电压补偿和自适应有功控制改进传统策略。Simulink多工况仿真结果表明,所提拓扑结构及控制策略具有较优动态性能,达到预期控制效果。

Abstract

Grid-forming wind turbine generator exhibits excellent performance in weak grids, providing frequency and voltage support to the grid. However, the integration of a high proportion of power electronic devices may lead to grid harmonic pollution, while failures of renewable energy clusters to ride through, faults can cause transient impacts on the grid, worsening power quality. To address these issues, this paper proposes the utilization of a Unified Power Quality Conditioner (UPQC) based on nine-switch converter to achieve harmonic mitigation and source-grid fault isolation, significantly reducing the risk of converter current exceeding limits. To suppress circulating currents generated by parallel operation of multiple turbines and enhance active support during grid-forming wind turbine cluster fault ride-through, the mechanism of virtual synchronous machine power coupling and transient power angle stability are analyzed. Traditional strategies are improved based on reactive power loop supplementary voltage compensation and adaptive active power control. Simulink simulation results under various operating conditions demonstrate that the proposed topology and control strategies exhibit superior dynamic performance, achieving the desired control effects.
