摘要

提出了一种具有轴向磁通永磁发电机无功补偿功能的单相并网系统。所提出的系统具有双重功能,即不仅通过AFPM传输任何类型的机械电源产生的能量,而且还提供无功功率来补偿负载所吸收的无功功率。该系统包括3个主要部分:5相实验室制造的交流AFPM、全桥整流器和IGBT全桥逆变器。采用了一种基于固定磁滞带的电流控制技术。所有控制算法均在dsPIC30F4011数字信号控制器(DSC)上实现。所提出的系统能够将所提出的AFPM提供的能量传输到单相,50 Hz, 220 V电源。该系统除实现电力传输外,还对阻感性负荷进行无功补偿,使电网的功率因数接近统一。对系统的性能进行了测试,结果令人满意。

Single-phase grid connected axial flux permanent magnet generator system with reactive power compensation functionality
This paper presents a single-phase grid connected system with reactive power compensation functionality for an axial flux permanent magnet (AFPM) generator. The proposed system offers bi-function namely not only transfers energy generated by any kind of mechanical power sources via an AFPM but also feeds reactive power to compensate the reactive power drawn by loads. The proposed system includes 3 main parts: the 5-Phase laboratory made AC AFPM, full bridge rectifier and an IGBT full bridge inverter. A current control technique based on fixed hysteresis band is used. All control algorithms are implemented on dsPIC30F4011 Digital Signal Controller (DSC). The proposed system is able to transfer energy supplied from the proposed AFPM to a 1-phase, 50 Hz, 220 V mains supply. Apart from the power transfer, the proposed system also provides reactive power compensation for resistive-inductive load to improve power factor of the grid to nearly unity. The system performance is investigated which appears satisfactory.
