摘　　要：交直流电力系统电压稳定性控制方法主要集中在单一的调节手段上进行定功率控制,导致电压区域不稳定,发生大规模波动,为此研究交直流电力系统电压稳定性控制方法。首先,通过对交直流电力系统的电压进行分区,揭示系统电压分布的特点和规律。电压分区后,构建储能单元的数学模型,针对直流配电网的惯性特性进行详细分析,确定电压稳定负荷裕度的计算方法,以评估系统的稳定性水平,最后,结合电压暂态稳定性控制输出,实现交直流电力系统电压稳定性控制。实验结果显示,与无功补偿方法和有功潮流优化方法相比,研究的交直流电力系统电压稳定性控制方法的交流子网的电压区域稳定,未发生大规模波动,具有实际的应用价值。The voltage stability control method of AC/DC power system mainly focuses on a single regulation means,which leads to voltage region instability and large-scale fluctuation,so the voltage stability control method of AC/DC power system is studied.Firstly,the characteristics and rules of voltage distribution in AC/DC power system are revealed by dividing the voltage of AC/DC power system.After the voltage division,the mathematical model of the energy storage unit is constructed,the inertia characteristics of the DC distribution network are analyzed in detail,and the calculation method of the voltage stability load margin is determined to evaluate the stability level of the system.Finally,according to the voltage transient stability control output,the voltage stability control of AC/DC power system is realized.The experimental results show that:compared with the reactive power compensation method and the active power flow optimization method,the AC subnet voltage region of the AC/DC power system voltage stability control method is stable and has no large-scale fluctuation,so it has practical application value.
