چکیده
With the large-scale construction of high-speed railway and wind farms, traction power supply system (TPSS) farms are connected through system. The three-phase unbalance grid voltage caused by TPSS will seriously affect traditional farms’ operation control. Considering to system's public point common coupling (PCC), farm's current control support strategy studied. Firstly, aiming suppress influence harmonics unbalanced TPSS, repetitive controller (RC) is introduced doubly-fed induction generator (DFIG). vector based on combination proportion integral (PI) RC adopted, where PI used adjust average value DFIG output regulator controls sinusoidal stator current. Secondly, designed reduce fluctuation TPSS's loads. By coordinating three measures putting in reactive compensation devices, working mode, limiting active power, farm station effectively supported. Finally, a simulation model with built verify proposed strategy's effectiveness.

The development of electrical railway systems leads to critical power quality problems in the power grid. This paper discusses a kind of half-bridge-based railway power quality compensator system (HBRPQC) that can compensate negative sequence currents, harmonics, and reactive power simultaneously. In order to keep the HBRPQC performance efficient for the different kinds of transformers used in ...
