摘要

介绍了一种基于耦合超导线圈超导磁能存储的模块化统一电能质量控制器（UPQC）拓扑结构。UPQC采用MgB2和YBCO两种类型的耦合超导线圈，最大限度地提高了超导体的利用率，以存储磁能，提高电能质量。这种新型拓扑通过集成先进的拓扑和控制策略，解决了电压波动、动态电压下降和谐波畸变等关键电能质量问题。仿真结果表明，该方法对电压谐波、电流谐波和三相电流不平衡的抑制率分别为68%、73%和98%。分别为7%，为改善电网电力质量提供了重大进展。

Novel CSC-SMES based modular unified power quality controller

This paper introduces a novel modular unified power quality controller (UPQC) topology based on superconducting magnetic energy storage (SMES) with coupled superconducting coil (CSC). Using coupled superconducting coils made of both

{MgB}_{2}

and YBCO types, the proposed UPQC maximizes the utilization rate of the superconductor to store magnetic energy for power quality enhancement. The novel topology addresses key power quality issues, such as voltage fluctuations, dynamic voltage sags, and harmonic distortions, by integrating advanced topology and control strategies. The simulation results show that the suppression ratios of voltage, current harmonic, and three phase current imbalance with the proposed UQPC are 68%, 73% and 98. 7%, respectively, offering significant advances to improve grid power quality.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
