摘　　要：小电网中的主导发电机对暂态频率稳定有决定性影响。然而,目前小电网暂态频率稳定评估缺乏定量指标。该文借鉴大电网指标,提出了适合小电网频率稳定评估的指标,进一步,结合主导发电机调速系统模型,分析其参数配置、死区、比率、积分、微分控制环节参数对于系统暂态频率稳定性的影响,揭示了主导发电机调速系统参数对小电网暂态频率特性的影响。The dominant generator in small power grid has a decisive influence on transient frequency stability.However, current transient frequency stability assessment of small power grid lacks quantitative indexes.Considering large power grid indexes,this paper puts forward small power grid frequency transient stability assessment.indicators based on the frequency of dynamic response curves.Further,combined with main generator speed control system model,this paper analyzes the effect of parameter configuration,dead zone,ratio,integral and differential parameters for controlling parameters on system transient frequency stability,and reveals the influence of main generator speed control system parameters on small grid transient frequency characteristics.
