高温超导磁储能系统(HTS SMES)是一项响应速度快、功率容量大的新兴技术，可以应对电力系统不断增长的挑战，保证可靠的电力供应。中国电力研究所使用两种最先进的高温超导导体BSCCO和YBCO带材开发了一台kJ-Range、20kW的中小企业。该SMES系统用于补偿功率下降和波动，以抑制低频振荡，提高电力系统的稳定性。本文提出了一种SMES系统的优化设计，以达到最大的能量容量。建立了一种基于IGBT的电压型变流器，用于控制SMES系统与外部电路之间的功率流。构建了以数字信号处理器(DSP)和微程序控制单元(MCU)为核心的控制系统。控制策略采用空间矢量脉宽调制。在动态电力系统仿真实验室对整个系统进行了毫秒级功率波动补偿实验。仿真结果验证了SMES系统的设计和控制电路的正确性，更重要的是验证了SMES系统在电网中的应用能力。
High-temperature superconducting magnetic energy storage systems (HTS SMES) are an emerging technology with fast response and large power capacities which can address the challenges of growing power systems and ensure a reliable power supply. China Electric Power Research Institute (CEPRI) has developed a kJ-range, 20 kW SMES using two state of art HTS conductors, BSCCO and YBCO tapes. This SMES system is used to compensate a power drop and a fluctuation in order to damp low frequency oscillations to increase stability of a power system. This paper presents an optimized design of the SMES system to achieve a maximum energy capacity. A voltage source converter using IGBTs is built and can be used to control the power flow between the SMES system and external circuits. A control system using a digital signal processor (DSP) and micro-programmed control unit (MCU) is constructed. SVPWM pulse modulation is used as a control strategy. The whole system was experimentally tested for compensation of power fluctuation within milliseconds in a dynamic power system simulation laboratory. The result validates the design and control circuit, and more importantly, the application capability of SMES systems in a power grid.
