Study on PSCAD Based Traction Power Supply System Simulation

介绍了电力系统仿真计算程序PSCAD的特点,基于PSCAD建立了电气化铁道牵引供电系统的仿真模型库,利用该模型库可以对不同接线形式的牵引变压器、不同的供电方式和电气化机车进行各种稳态和暂态仿真研究。本文根据所建模型实现了普通铁路和高速铁路牵引供电系统在直供带回流和AT供电方式下的数字仿真,以计算在不同的系统短路容量和变压器容量和变压器类型下,接触线和钢轨的电压分布,并将仿真结果与解析法的计算结果进行了比较。研究表明,本文建立的电气化铁道牵引供电系统仿真模型库具有高度的灵活性和较高的精度,可以满足工程要求。

Introduced the characters of PSCAD, a simulation models data of electrical railway traction power supply system based on it is created. Using this data, different type of connection traction transformers, different form of power supplys and electrication locomotives are to be researched on their transient and steady simulation states; direct power supply and AT power supplydigital simulations based on ordinary railway and high-speed railway traction power supply system are accomplished. Based on different s...
