葛洲坝大江电厂交直流切机系统的研发与应用

The Study and Application on Generator Switch off System of Gezhouba Dajiang Power Station

为满足西电东送的系统要求,葛上直流输电系统对华东地区送电功率将增加到1200MW。为了在这种工况下维持整个华中网系统和葛洲坝系统的安全稳定运行,由华中网调、华中科技大学、葛洲坝大江电厂共同研制开发了QWD型交直流切机稳定装置。对该交直流切机稳定装置的研发和应用情况进行了全面的介绍,电力系统工作者在考虑交直流输电系统的安全稳定运行问题时,可以此为参考。

The power of Gezhouba-Shanghai DC transmission System for east china will increase to1200MW for filling the demand of transmitting electric power from west china to east china.The QWD type AC and DC dynamo switch off stabilizator which maintain the safe running of central china power grid and Gezhouba system,was devel-oped by central china power grid dispatching?central china science and technology university and Gezhouba Dajiang power station.This paper introduces the study and aplication of the QWD.
