摘　　要：为了对电力系统电压相位进行实时检测和采样,实现高温超导磁储能(High Temperature Superconducting Magnetic Energy Storage,简称HT-SMES)功率变换器的快速功率变换,基于TMS320F2812型DSP数字控制,提出了一种硬件锁相方法,并应用在HT-SMES功率变换器的信号采样和调理电路中。实验结果表明,该方法能有效抑制电网输入侧的电压谐波分量,对电网电压相位进行准确跟踪和锁定,具有动态响应快,稳态性能好的特点。For tracking the voltage phase of power system in real time,a hardware phase-locked method based on digital signal processor （DSP）TMS320F2812 is proposed in the sampling and conditioning circuit on high temperature supercon-ducting magnetic energy storage （HTSMES）power converter so as to obtain fast power conversion.The experimental result shows that with the fast dynamic and good steady performance,this har, tware phase-locked method can suppress the voltage harmonic and trace the voltage phase of power system accurately.
