摘要
以定州电厂660 MW超临界机组为研究对象,建立了机组简化的数学模型。在STAR 90仿真平台的基础上,通过一系列动态特性试验,利用MATLAB系统辨识仿真工具箱(SIST),辨识出了适用于100%负荷条件下的模型传递函数。经检验,所得模型准确度较好,对超临界机组控制器的研究有一定参考价值。
Aiming at the 660 MW supercritical unit of Dingzhou Power Plant,a simplified mathematical model of the unit is built.Based on STAR-90 Simulation Support System,a series of experiments on dynamic characteristic is performed.Then the transfer function model that fit for 100% load condition is identified by using System Identification and Simulation Toolbox（SIST） in MATLAB.The test results show that,the veracity of the proposed model is well,and the model have certain value for the research on supercritical unit controllers.
