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

A. Sanga, U. Prasad, R. Rohan

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 power quality issues, for instance, sub-harmonics negative gathering present, reactive 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 imperfections. Likewise, THD level is figured utilizing FFT investigation which is <5%.The proposed strategy and innovation is tried on MATLAB/SIMULINK condition.
