Transient stability linear parameter varying robust feedback control for interconnected power system by wind power AC/DC channel
摘要
Abstract
In view of the variable parameters that affect the transient stability of electromagnetic torque and mechanical torque balance in AC / DC systems,combined with the uncertainty of large-scale wind power,this paper proposes to control the power of DC channels and the mechanical power in the interconnected system,A robust feedback control method based on transient stability of interconnected systems with variable parameters is proposed to improve the transient stability of the system interconnected by AC and DC wind power channels. Aiming at the strong nonlinearity of the transient process of interconnected systems,a linear variable parameter model is established. According to the power difference and uncertainty of wind power output of the transient system,the transient process of the system is designed as a linearized model with variable parameters.Design H∞Robust Output Feedback Controller for Linear Variable Parameter Model and Its Online Solution Algorithm. According to the linear variable parameter design point and robust controller,the topology and transfer function of transient stability control strategy for interconnected systems are proposed. The simulation results show that this paper presents a robust feedback control model of linear variable parameters with good response characteristics and transient stability control effects.关键词
