In the paper, firstly, the authors present an efficient computational algorithm to evaluate the short circuit capacity distribution at a substation bus, and on basis of this distribution to specify the minimum short circuit capacity for the year under evaluation. Secondly, the authors estimate the maximum traction load at seven 161kv substations of Taiwan high-speed railway system which is now under planning. Thirdly, using the maximum traction load and the minimum short circuit capacity derived, the authors estimate the maximum unbalance of the 3{phi} voltage at these seven 161kv substations, and compare their results with that by Taipower to demonstrate the effectiveness of their proposed algorithm.
