DESIGN ASPECTS OF TRACTION SUBSTATION 4.O SPACING AND LOCATION 4.01 The sub-station spacings largely depends upon the permissible voltage drop at the farthest end, which in turn depends upon various factors such as the traffic to be moved, anticipated traffic in the future and gradients of the section to be electrified. The voltage drop at the farthest end is calculated both for normal and extended feed condtions on the basis of given combination of trains on UP & DOWN tracks, loads and specified speeds, track parameters of the section on the assumed length of the feed zone. The calculations are repeated for different assumed lengths of feed zone and it is ensured that the voltage at the farthest end is within the permissible limits. 4.02 Alternatively, the power requirement is calculated on the basis of average specific energy consumption of goods and passenger trains Following figures of specific energy consumption are taken for level or lightly graded sections. (a) Goods train - 11 kwh. 1000 GTKM (b) Pass train - 19 kwh. 1000 GTKM For Medium or heavily graded sectins, the specific enery consumption figures have to be based on trials. The power requirement is calculated by the formula as given below :- Where, Q x (2Lo) x W 60 1 P = X X KVA 1000 H cosø 2 X Lo = Sub-Stn. covering area for double track line(km) W = Weight of a train in tones Q = Energy consumption rate (kwh/1000 GTKM) H = Headway in minutes during peak time (assumed) COSø = P.F. (lagging) Conversely, using the above formula ‘Lo’ can be calculated for a given rating of traction transformer. Typical calculation based on this formula is shown below - 72
