讲座摘要：
The traction power supply system is one of the four core systems of electrified railway. At present, the vast majority of electrified railways in the world adopt a single AC power frequency system, and the traction power supply system adopts a phase separated and segmented power supply method, which means that there is neutral section (no power zone) within and between traction substations, resulting in problems such as the inability to exchange energy along the entire railway line, high safety hazards, difficulty in cross regional power supply, difficulty in utilizing regenerative braking energy of a large number of trains, and difficulty in connecting new energy sources. In order to solve a series of problems caused by electrical phase separation in the traditional traction power supply system, the Flexible Traction Power Supply System (FTPSS) based on Multi-Level Converter (MLC) has attracted widespread industry attention. FTPSS can be regarded as a new micro-grid traction power system composed of grid-forming and grid-following converters. Distributed energy resources in this system have special characteristics in terms of capacity, distribution, and locomotive load. This tutorial will provide an overview of the FTPSS proposed by our research team, the integrated coordinated control strategy of FTPSS, and the topology, control method and reliability of the MLC in the traction power supply system.
