摘要:
 针对电气化铁路大容量负荷补偿需要和补偿装置容量优化问题,提出一种基于模块化多电平变换器( modular multilevel converter,MMC) 的单三相组合式同相牵引供电系统。分析了系统的主电路结构和工作原理。以电能质量国标限值为约束,建立了系统电能质量综合补偿模型,并与预测电流控制相结合,构建了同相补偿装置分层控制策略。与传统同相供电系统比较,该系统可以适应高压、大容量需求,取消牵引匹配变压器,同时实现降低补偿装置容量和提升系统动态响应的目的。通过模拟分析了实际牵引负荷的多种运行工况,来验证上述同相牵引供电方案的可行性和优化控制策略的正确性。
Abstract:
 Aiming at the compensation requirement of large capacity load and the capacity optimization of compensation device for electrified railway,a single-three combined co-phase power supply system based on modular multilevel converter ( MMC) is studied. The main circuit structure and working principle of the system are analyzed. Constrained by the national standard limit of power quality,a comprehensive compensation model for power quality of the system was established,and combined with predictive current
control,a hierarchical control strategy for co-phase compensation device was constructed. Compared with the traditional co-phase power supply system,the system can adapt to the high-voltage and large-capacity requirements,cancel the traction matching transformer,and achieve the purpose of reducing the capacity of the compensation device and improving the dynamic response of the system. Through simulation and analysis of various operating conditions of the actual traction load,it verifies the feasibility of the above power supply scheme and the correctness of the optimal control strategy.
