ABSTRACT: Co-phase power supply system can solve the problems of
power quality of heavy unbalanced three phase, large harmonics and reactive
power and cancel neutral section in electric railway power supply system. In
order to do further research, a co-phase power supply test system is proposed.
By mean of analyzing on structures and principles of YNvd transformer, integrated power
flow controller (IPFC) and simulation load, establishing control strategy on IPFC
and simulation load, the system is simulated dynamically. The results illustrate
that the scheme can well simulate co-phase system, and the negative sequence is
eliminated, harmonic and reactive power are real-timely compensated in system.
