  "description": "<p>The transmission line in an electrified railway system must provide power transmission within<br>\nthe voltage limit at safe and quality conditions. Therefore, system analysis within the traction<br>\npower system is vital to the design and operation of an electrified railway. Loads in traction<br>\npower system are often characterized by their mobility, wide range of power variations,<br>\nregeneration and service dependence. One of the main problems in the railway supply stations<br>\nare the voltage drops due to the changes of the load. Voltage drop in electrified railway have an<br>\ninfluence on the location of traction substation (reduces distance between traction transformer<br>\nand section post length) and operating railway transport in a such condition disturbs<br>\ntransportation system, as a result the reactive power compensator should be installed to have a<br>\nbetter voltage at receiving end.<br>\nEthiopian railway cooperation is constructing national railway transport from Sebeta to Meiso<br>\nwith seven feeding traction substation from Sebeta to Adama. In this thesis traction network<br>\nvoltage drop analysis is undertaken for various feeding condition. Taking sample section from<br>\nSebeta substation to Indode substation analyses of the traction network voltage drop over the<br>\nfeeding condition has been conducted for different loading cases. The modeling and simulation<br>\nof the system is done by MATLAB/SIMULINK software</p>",
