电气铁道牵引站谐波的测算

ON HARMONIC PREDICTION IN TRACTION SUBSTATION OF ELECTRIC RAILWAYS

本文根据山西省雁同电网某牵引站的电铁谐波实测数据对文［１］提出的简化公式在预测牵引站谐波上的误差作了检验。

In this paper according to the fielddataof harmonics in a traction substation of Yan-TongPower Network(Shanxi province,China the simpli-fied forrnulas,which are based on assuming unchangedcurrent wave forms and a same phase difference between currents and fundamental voltage in a feedingsection,are checked on the errors of predicting har-rnonics in a traction substation,The connection oftractiOn transformer concerned in the paper is Star-Delta,and the type of locomotives is SS-1(made inChina).
