Research of Low Voltage Shore Power Supply Used on Shipping Based on Sliding Control
In order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...
متن کاملRating Reduction and Optimized DC-Link Voltage of the HPQC in Co-Phase Traction Power System
Electric traction trains are huge non-linear single-phase loads influencing adversely on power quality parameters on the grid side. Hybrid power quality conditioner (HPQC) has been utilized to compensate current unbalance, harmonics, and low power factor in the co-phase traction system simultaneously. By incrementing the traction load, the rating of the HPQC increases and may constraints its ap...
متن کاملPower Quality Improvement in Traction Power Supply Networks
AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption ofreactive power are further power quality problems that the supply network is encountering. In this paper, acompensation strategy with the aid of Railway Power Conditioner (RPC) is proposed to over...

متن کاملEMC’04/Sendai Characterization of AT railway traction power supply, measurement system and results
Tests at the new ‘Havenspoorlijn’ (Harbor Railway Line) in The Netherlands asked for the measurement of all currents at eight positions of the railway. The differentiating/integrating measurement scheme with Rogowski coils and special integrators fulfilled the requirements with respect to accuracy, bandwidth, electromagnetic compatibility, life-time and environmental constraints. The sensors al...
