A comprehensive control strategy of railway power quality compensator for AC traction power supply systems
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 ...
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 کاملPower Quality Conditioners for Railway Traction - a Review
Railway traction is a more stochastic heavy load connected system. Due to the usage of ac-dc converters and ac-ac converters, the various power quality issues become the major problems in the electric system. This paper presents a review on power quality conditioners suitable for Railway traction based on the configuration, components involved and on the technical and economic considerations. M...
متن کاملMeasurements on 25 kV Traction Power Supply Systems
At the moment 25 kV traction power supply systems are being introduced in the Netherlands. Currently in the Netherlands a 1500 V DC system is used, however due to increasing energy demands this system is no longer sufficient. For the high-speed lines and heavy freight lines, which are under construction, the 2x25 kV AC system has been chosen. Introduction of this new technology leads to differe...
