摘　　要：提出了一种用于配电网模块式集成的高温超导储能系统(HTS-SMES),设计了级联式1MJ/500kVA/10kVHTS-SMES的系统结构和运行原理。模块式高温超导储能系统(SMES)的电力集成主要包含3部分,一是MJ级的高温超导储能磁体,设计了12单元模块组合式环形高温超导储能磁体,解决了其漏磁场问题;二是用于磁体直流电流与逆变器直流电压变换的DC-DC换流器,提出了一种不对称级联式电流调节器,解决了其关断损耗问题;三是用于直流电压与交流电压变换的并网DC-AC逆变器,采用了级联式逆变器结构,解决了高压和波形质量。最后,对于1MJ/500kVA/10kV模块式集成SMES进行了仿真试验,验证了其有效性。A modular integrated high temperature superconductor-superconducting magnetic energy storage （HTS-SMES） concept is proposed for distribution grid application, and its cascaded configuration and operating principle on a 1 MJ/500 kVA /10 kV HTS-SMES are analyzed. Modular integrated HTS-SMES comprises three aspects on the power integration application： one is the MJ HTS superconducting magnet, and a 12-module HTS toroidal magnet is given to reduce the fringe field outside 1 MJ. Another is a DC-DC chopper to convert the direct magnet current to the direct inverter voltage, and a asymmetrical cascaded current regulator is presented to overcome its switching losses problem; the other is the inverter to connect with the grid to convert the direct inverter voltage to the alternating sine voltage, and a cascade inverter is introduced to provide high voltage and high-quality wave. At last, the modular integrated HTS-SMES concept is verified on the simulation.
