荆门热电厂6号机组励磁系统建模研究

Study on the Excitation System Model Building for Unit No.6 in Jingmen Co-generation Plant

荆门热电厂6号机组为东方电机有限公司生产的640MW汽轮发电机组,采用ABB公司生产的UNITROL 5000系列微机励磁调节器。本文介绍了根据荆门热电厂6号机组励磁系统参数测试结果,建立电力系统稳定计算用数学模型并计算其参数的方法,建模结果通过仿真校核证实是正确有效的。

The digital automatic voltage regulator(AVR)with the type of UNITROL 5000,produced by ABB Ltd.,is used on the 640MW steam turbine generating unit no.6 in Jingmen Co-generation Plant,which is manufactured by Dongfang Electrical Machinery Company Ltd.Based on parameter testing results of the excitation system,methods to obtain mathematical model and parameters used in power system stability study are presented in this paper,and the correctness and effectiveness of model building results is justified by numerical simulations.
