摘　　要：在以往对柔性功率调节系统的研究当中,从未将整流侧功率纳入考虑范围,与传统将双馈转子侧逆变器供电等效为直流的情形不同,结合改进的空间矢量脉宽调制方法使系统的功率调节范围得到进一步拓展。提出了以电网电压定向为核心的包含逆变功角为变量的系统整体控制策略,对系统内的双馈电机及其驱动、惯性储能飞轮以及网侧整流器均进行了完整的数学建模与控制系统构建,并且完成了仿真以及系统功能验证,为系统的优化和运行提供了重要的理论依据。Previous studies on related systems have not considered the impact of power on the rectifier side.Unlike traditional approaches where the double-fed rotor-side inverter is equivalent to a DC source,this paper integrates an improved space vector pulse width modulation(SVPWM)method to extend the power regulation range of the entire system.Building on this,a system-wide control strategy based on grid voltage orientation is proposed,incorporating the inverter angle as a control variable.Comprehensive mathematical modeling and control system design are carried out for the double-fed motor and its drive system,the inertia energy flywheel,and the grid-side rectifier.Simulation results and system functionality verification demonstrate the effectiveness of the proposed approach,providing a significant theoretical foundation for optimizing and improving the operation of the entire system.
