新建时速200 km客货共线铁路综合功率因数计算

研究目的:近年我国铁路建设事业迅猛发展,新建了大量时速200 km的客货共线铁路,由于新建线路上运营机车种类繁多,而电力部门又对铁路功率因数考核严格,因此需对牵引变电所功率因数进行研究。研究方法:通过对各种牵引负荷综合功率因数的计算来确定牵引变电所的功率因数。研究结果:利用此方法能较准确的反映牵引变电所的功率因数。研究结论:通过综合功率因数计算,可以较准确地求出客货共线线路开行不同类型、不同对数列车时牵引变电所的功率因数。

Calculation of Integral Power Factor of Newly-built 200 km/h Railway Line Shared by Passenger and Freight Trains

Research purposes: In recent years,with the rapid development of Chinese railway construction,a lot of 200 km/h railway lines shared by passenger and freight trains are newly built.Because the types of the operating locomotives are various for the newly-built lines and the power factor of railway is examined strictly by the power supply departments,it is necessary to make a research about power factor of traction substation.Research methods:The power factor of traction substation is determined through calculation of integral power factor of various traction loads.Research results:This method can be used to more accurately reflect the power factor of traction substation.Research conclusions:By the calculation of integral power factor,the power factor of traction substation can be worked out relatively accurately under the condition of the different types of locomotives and the different pairs of trains on railway line shared by passenger and freight trains.
