飞轮脉冲电源放电过程的建模与分析
Modeling and analysis of discharging process of flywheel energy storage system
摘要
Abstract
A model for predicting the transient behaviors of a synchronous generator in rotating dq reference frame is derived, and the accuracy of the model is verified by 3-phase short circuit experiments on a 3-phase 5.5 kW synchronous machine. According to the different assignments of the excitation system in the discharging process of the flywheel energy storage system ( FESS ), the discharging process of the FESS is divided into two stages. In the first stage, the excitation voltage is maintained till the output voltage rises to its rated value. In the second stage, the excitation voltage is adjusted to maintain the rated output voltage. By involving the excitation system constraint equations of the two stages, the calculation model for the discharging process of the FESS is derived based on the proposed synchronous generator model. Finally, the FESS's discharging model is calculated and discussed under specific parameters and initial conditions. The results show that this calculation model is effective for predicting the dynamic performance of the synchronous generator in the discharging process of the FESS.关键词
