A Negative Sequence Compensation Using PID Controller Based RPC in High Speed Railway Traction

Abstract

Traction loads are changing intensely and as we presumably are mindful that trains exhibit
the properties of non-linearity and single stage electrical weights. Distinctive power quality
issues that are made by the electric traction critically influence the present dispersal system
orchestrate. The wellspring of force quality issues, for instance, sub-music negative gathering
present, responsive power use and load unevenness. The power quality may get decrease if
the get ready is running at higher speeds or gets ready with a heavier load. To conquer these
unbalance control gadgets can be introduced, for example, Railway control conditioner
(RPC) which can relieve unbalance in the framework as ready to decrease the level of
current unbalance altogether. This postulation decides the RPC as powerful answer for the
railroad traction framework. Additionally contemplates have been done keeping in mind the
end goal to propose a control procedure for RPC alongside PID controller to enhance
control factor, diminish harmonics and unbalance voltage because of current flaws. Likewise,
THD level is figured utilizing FFT investigation which is <5%.The proposed strategy and
innovation is tried on MATLAB/SIMULINK condition.
