摘　　要：为提高电力系统动态稳定性,实现高温超导储能系统对电网电压跌落的有效补偿,采用三单相H桥型拓扑结构,搭建了一个电压型高温超导储能系统功率变换器。对控制系统、信号调理系统、功率和驱动保护电路进行了设计;基于SPWM脉冲触发方式,应用TMS320F2812型DSP实现了动态电压瞬时跌落补偿的全数字闭环控制,给出了相关的软件程序设计方法。补偿电压实验波形表明该变流器具备应用高温超导储能系统进行动态电压跌落补偿的性能要求。To compensate the voltage drop and improve the dynamic stability of power supply,a voltage source converter with the topology of three single-phase H-type bridges is proposed for the high temperature superconducting magnetic energy storage system. Its control system, signal conditioning system, power conversion circuit and drive ＆ protection circuit are designed. TMS320F2812 DSP is applied to implement the full-digital close-loop control for instantaneous voltage sag compensation based on SPWM and its relevant software program design is presented. The experimental results show the effectiveness of the designed converter in dynamic voltage sag compensation.
