摘要

研究了基于自抗扰技术的可变速抽水蓄能机组交流励磁控制系统。文中考虑逆变器对输出电压的影响，建立了变速机组的数学模型，以此为基础设计了二阶自抗扰控制器，并提出了基于自抗扰技术的交流励磁控制系统。文中通过仿真对所提励磁系统的可行性以及控制性能进行了定量的分析，结果表明，该励磁系统能够很好地控制可变速机组的发电以及抽水两种工况，且较传统比例—积分(PI)控制器具有更好的动态性能以及鲁棒性。

Abstract

This paper focuses on the AC excitation control system of variable speed pumped storage units(VSPSU)based on active disturbance rejection control(ADRC). Firstly

the mathematical model of VSPSU is proposed that takes into account the effects of the inverter. Then

a second order ADRC is presented as well as an AC excitation control system based on stator flux oriented control to control the active and reactive power of the VSPSU. For verification

a system of VSPSU is built in MATLAB/Simulink to perform simulations with respect to the proposed ADRC. The simulation results show that the proposed control system can achieve control of the output power of VSPSU in both the generating and pumping mode by virtue of its good dynamic performance and robustness.
