摘要
文章利用等效虚拟惯性时间常数定量表征风电场惯性响应,采用传递函数模型描述风电场一次调频响应,结合再热式火电机组和水电机组的原动机-调速器模型,针对含多个风电场/火电机组/水电机组的电力系统提出了改进SFR解析计算等值模型,用于分析计算含风电虚拟惯性响应和一次调频的电网频率响应特性。仿真结果表明,改进SFR模型能更真实地反映含风电惯性/一次调频响应作用的电力系统频率特性,为客观评估高风电渗透率下的电力系统频率稳定运行状态提供了理论基础。
In this study, the inertial response of wind farm is expressed quantitatively utilizing the equivalent inertia time constant, and the primary frequency response of wind farm is described employing transfer function model. Furthermore, combining with prime mover-governor model of reheat thermal power units and hydropower units, the modified SFR(System Frequency Response)analytical calculation equivalent model is established finally towards the power system comprising multiple wind farms, thermal power units and hydropower units, which is used to analysis and calculate frequency-response characteristic of power system incorporating virtual inertial response and primary frequency modulation of wind farm. The simulation results show that the frequencyresponse characteristic of power system incorporating virtual inertial response and primary frequency modulation of wind farm was presented more really using the modified SFR model,which provides a theoretical basis for objectively assessing frequency stability of power system with high wind power penetration.
