牵引供电系统牵引网的四端网络级联模型及其仿真

A MODEL AND ITS ALGORITHM OF 4-END NETWORK CAS-CADED FOR THE ELECTRIFIED RAILWAY TRACTION NET-WORK

本文针对牵引供电系统的ＡＴ、ＢＴ、直供、单线、复线等型式和各种供电方式的牵引接触网的电气特性，建立了一个统一的数学模型，即四端网络级联模型。该模型及其仿真算法适用于牵引供电系统仿真器（ＴＰＳ）的研究与开发。

This paper introduces a simulation model and its algorithm of 4-end network cas-caded for the overhead lines of traction power system，which are applicable for the schemes ofAT、BT and so on. The model and its algorithm can be applied to the research and develop-ment of the traction power simulator（TPS）．The results testify the validity and the feasibili-ty of TPS.
