摘 要:为了研究不同程度的负载波动对系统频率偏差的影响,提出了考虑不同干扰类型和不同扰动程度的电力系统频率响应频域分析模型。基于该模型推导了电力系统频率响应惯性常数的表达式,以及使用Simulink仿真了负载瞬间变化时对电力系统频率响应的影响。仿真结果表明,同等程度的负载变化对频率影响相似,负载增量越大,频率下降的程度越大,下降时间越长。

    Abstract: In order to study the influence of different degrees of load fluctuation on the system frequency deviation, this paper proposed a frequency domain analysis model of power system frequency response considering different disturbance types and different disturbance levels. Based on the model, this paper deduced the inertia constant expression of power system frequency response and simulatedthe influence of transient load on the frequency response of power systemwith Simulink. The simulation results show that the same degree of load change has similar effect on frequency.The larger the load increment, the greater the frequency decrease and the longer the fall time.
    Key words: load change; frequency response; inertia constant; frequency adjustment
