| 摘要: |
| 同相供电是解决传统牵引供电系统及单重同相供电方案存在的过电分相、电能质量欠佳及结构、控制算法缺陷等技术瓶颈的关键技术之一，是实现电气化铁路朝着安全、高速、重载方向发展的必然途径。在单重同相供电技术的基础上，从系统结构改进和控制算法优化两方面入手，通过融合电力系统柔性输电并网及多重化逆变等技术，提出负序消除以及无功、谐波抑制能力更优的新型四重化同相供电方案。最后，设计并搭建出新型同相牵引供电系统的仿真模型，通过一系列仿真试验对所提出的方法进行了验证，并取得了预期的效果。 |

| Abstract: |
| Co-phase power supply is one of the key technologies to solve the technical bottlenecks such as electrical phase separation zone, poor power quality and defects in structure and control algorithms in traditional traction power supply systems and single co-phase power supply schemes, and an inevitable way to realize the development of electrified railways in the direction of safety, high speed and heavy load. Based on the single co-phase power supply technology, a novel quadruple co-phase power supply scheme with negative sequence elimination and to suppress reactive power and harmonic better for the two aspects of the system structure improvement and control algorithm optimization is proposed by combining the technologies of power system flexible transmission grid-connected and multiple inverters. Finally, the simulation model for the novel co-phase traction power supply system was designed and built, and the present method was verified by a set of simulation experiments so as to obtain the expected results. |
