Modeling of Load Frequency Characteristics in the Load Model for Power System Digital Simulation

Based on deepen research in frequency characteristics of power load, a method to solve parameters of load model frequency characteristics is proposed. The static load frequency factor is calculated from weighted sum of each static load component's power in the load station. The statistic synthesis method and fault fitting method are combined to calculate the load frequency parameters of power generators cluster in the whole load station. Finally, the effectiveness of proposed method is proven by simulation results.
