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.
