摘要
针对双馈感应发电机的动态行为分析不够精准,导致技术的控制效果不佳的问题,设计双馈感应发电机直接转矩滑模变结构控制。根据双馈感应发电机的运行特点,分别计算双馈感应发电机的磁链方程、电压方程、转矩方程和运动方程;确定双馈感应发电机的滑模面并计算对应的切换函数,确定相应的控制律;设计滑模变结构控制器,通过整定控制参数计算对应的控制误差,实现对发电机的控制。实验结果表明:双馈感应发电机采用的直接转矩滑模变结构控制技术在实际应用中超调量较低,控制效果较好。
In response to the imprecise analysis of the dynamic behavior of doubly-fed induction generators,which leads to poor control effectiveness of the technology,a direct torque sliding mode variable structure control for doubly-fed induction generators is designed.The magnetic flux equation,voltage equation,torque equation,and motion equation of the doubly-fed induction generator are calculated based on its operating characteristics.Then the sliding mode surface of the doubly-fed induction generator is determined,and the corresponding switching function is calculated to determine the corresponding control law.A sliding mode variable structure controller to control the generator is designed by tuning control parameters and calculating corresponding control errors.The experimental results show that the designed direct torque sliding mode variable structure control technology for doubly-fed induction generators has lower overshoot and better control effect in practical applications.
