Probability Distribution for the Feeder Current of Traction Substation
Li-Yan Zhang, Qunzhan Li, Xing Xiao-qian · 2009
Probability density function for feeder current of traction substation is fitted by using beta function through the theory of stochastic process and method of numerical analysis, and the distribution characteristic of feeder current is generalized and analyzed based on a great deal recorded feeder current data. The feeder current sample, which will supply more detailed information for the procedure analyse of the feeder current, is obtained by using Monte Carlo method. The statistical regularity of simulation results is basically same to the recorded data of traction substations by comparing, which verifies the effectiveness of the proposed method.
