十二脉动单元接线方式换流站数学模型

A Mathematical Model of Converting Station with Twelve Impulse Unit Connection

单元接线方式具有接线简单，投资节省等一系列优点，直流输电系统的换流站接线采用单元接线方式是一新课题。本文在精确考虑换流器工作过程的基础上提出一个新的单元接线方式数学模型，该模型包括发电机、变压器、换流器及直流输电线路。结果表明。它能够较精确地仿真单元接线方式的实际运行情况。

The unit connection is a new way applied to HVDC, it wb exploit greatly the latent advantage in HVDC teachnology. A new mathematical moded with unit connaction is offered based on that the converter operating process is thought accurately, it includes a generator, a transformer model, converter and a transmission line. The simulation results shows that it is able to s￣te accurately the practical operating conditions of generator-converter syStem with unit connection.
