摘要
传统的开关磁阻发电机(SRG)调速系统中的位置传感器给其推广应用带来了诸多限制,如系统结构的复杂度加大、成本提高、可靠性降低等。本文采用高性能DSP实现数字磁链积分器,然后根据电机的磁链模型,利用磁链、相电流对转子位置进行估算。本控制系统在风力发电实验中证实了位置观测误差小,系统动态特性好,速度调节范围宽。无位置传感器开关磁阻发电机控制系统简单可靠,可实现更有效地利用风能。
Mechanical position sensors of traditional Switched Reluctance Generator (SRG) drive have brought many restrictions in its application, such as increasing complexity of structure, raising cost, decreasing reliability and so on. Digital flux linkage integrator supported by high performance DSP was proposed. According to flux linkage model of SRG, rotor position was estimated by flux linkage and phase current. The experimental results of wind generation verified validity and feasibility of the proposed sensor...
