摘　　要：针对海上风力发电系统容易受到外界因素影响,难以精准地判断稳态电压运行状态的问题,设计一种海上风力发电集中系统稳态电压稳定分析方法。根据正切向量内部数据信息识别不同发电集中系统对电压数据的管理程度,抑制内部电压和电流并记录此时的频率值,设置相应的母线支路与变压器装置,控制电压负荷高低。分析发电系统电力输出功率与电压失稳状态瞬间数值,调整电压使其达到长期状态下的平衡点,增强整体系统的平衡点汇聚性能,时刻记录系统内部电压增幅震荡数值,通过数据获取不同时间段内的的稳定电压值。实验结果表明,当变压器出现故障时,故障持续时间仅为0.4 s,表明该文方法具有一定的调节能力,保持系统电压处于稳态。It is difficult to accurately determine the steady⁃state voltage operation status of offshore wind power generation systems due to their susceptibility to external factors.This article designs a steady⁃state voltage stability analysis method for offshore wind power generation centralized systems.According to the internal data information of tangent vector,identify the management degree of voltage data of different centralized power generation systems,suppress the internal voltage and current and record the current frequency value,set the corresponding bus branch and transformer device,and control the voltage load.Analyze the instantaneous values of power output and voltage instability in the power generation system,adjust the voltage to reach the equilibrium point in a long⁃term stable state,enhance the convergence performance of the overall system’s equilibrium point,constantly record the internal voltage amplitude and oscillation values of the system,and obtain stable voltage values in different time periods through data.The experimental results show that when a transformer malfunctions,the fault duration is only 0.4 seconds,indicating that the method proposed in this paper has a certain regulating ability to maintain the stable voltage of the system.
