Abstract

The work is devoted to the development of a control system for a wind generator with the use of a switched reluctance motor. The search for new structures for the construction of the power unit and control system of electromechanical systems of wind power complexes is an urgent task of today. The most common construction options for such systems include double-fed induction motors and permanent magnet synchronous generators. In the first case there is no possibility of full control of the flow of power transmitted to the network, and in the second case the main disadvantage is the high cost of such an electric machine, which is explained by the use of rare earth materials in its design. The use of a switched reluctance motor as a generator has significant differences compared to similar use of electric machines based on torque generation due to the Lorentz force. A mathematical model of the electromechanical system of a wind generator with a switched reluctance motor in the Matlab / Simulink environment was developed. It was shown by mathematical modeling that when changing the sign of load torque, the machine does not go into braking mode independently, as is the case with other electric machines. This creates considerable difficulties in the operation of such a system, since the transition to brake mode requires a change in control effects on the switched reluctance motor. Features of functioning of the switched reluctance motor in the mode of regenerative braking have been stated. The limits of change of control angles which allow to receive the maximum amount of the generated electric energy and reduction of pulsations of brake torque of the machine have been defined. The structure of the control system of a switched reluctance motor has been developed, which involves the use of a modified speed controller, which divides its output signal into a sign function, which is subsequently used to select the converter control angles, as well as the absolute value used in the operation of the modulation algorithm of the required current magnitude .

开关磁阻电机风力发电机系统
本文致力于开发一种使用开关磁阻电机的风力发电机控制系统。为风电机组的动力单元和机电系统控制系统的建设寻找新的结构是当前的一项紧迫任务。这种系统最常见的结构选择包括双馈感应电动机和永磁同步发电机。在第一种情况下,不可能完全控制传输到网络的功率流,在第二种情况下,主要缺点是这种电机的成本高,这可以用稀土材料在其设计中使用来解释。开关磁阻电机作为发电机的使用与基于洛伦兹力产生扭矩的电机的类似使用有显着差异。在Matlab / Simulink环境下建立了开关磁阻电机风力发电机机电系统的数学模型。通过数学建模表明,当负载转矩的符号发生变化时,机器不会像其他电机那样独立进入制动模式。这在这样一个系统的操作中造成了相当大的困难,因为过渡到制动模式需要改变对开关磁阻电机的控制效果。阐述了开关磁阻电机在再生制动模式下的工作特点。定义了控制角变化的极限,以允许接收最大数量的产生的电能和减少机器的制动扭矩脉动。开发了开关磁阻电机控制系统的结构,其中涉及到使用改进的速度控制器,将其输出信号分成符号函数,随后用于选择变换器控制角度,以及所需电流大小的调制算法操作中使用的绝对值。
