固态变压器是一种含有电力电子变换器且通过高频变压器进行磁耦合的变电装置。它不仅能够实现电力系统中的电压变换、能量传递,还可以灵活控制变压器一次侧、二次侧的电压幅值和相位。此外,它能使系统具有更高的稳定性,实现更加灵活的输电方式,整合各种交直流分布式电源,以及实现电力市场下对功率潮流的实时控制。基于固态变压器的AC-DC-AC电路拓扑结构,提出了一种三相三线制高频隔离型固态变压器的实现方案,分析了该固态变压器输入级、隔离级、输出级的控制策略,并利用Matlab/simulink建立了10kV/380V仿真模型,仿真结果表明,提出的SST的实现方案和控制策略对10kV系统的电压、功率、频率控制效果...

A solid state transformer is a transformer device that contains a power the magnetic coupling through the high frequency transformer. Not only achieving electronic converter and it carries out voltage conversion, energy transfer of the power system, but also the flexibility to control voltage amplitude and phase of the transformer primary side and sec- ondary side. In addition, it can make the system with higher stability, achieve a more flexible transmission, integrated a variety of AC and DC distributed power, and achieve real- time control of power flow on the electricity market. Based on t...
