摘要

对汽轮机及其调节系统参数实测方法进行了研究

分析了控制逻辑、现场信号采集方法、PID控制器的输入/输出特性测试等对参数辨识的影响

参数实测方法不当将影响参数的辨识和仿真校核的准确性。为此

根据Q/GDW 748—2012《同步发电机原动机及其调节系统参数实测与建模导则》的要求

提出了基于校核的汽轮机及其调节系统参数的实测方法。

Abstract

Test methods for parameters of steam turbine and its governing systems were investigated.The effect of such factors as control logic

field signal acquisition method

input/output characteristics testing of the PID controller on parameter identification was analyzed.It was pointed out that improper measuring method would affect the parameter identification and accuracy of simulation check.Therefore

checking based measuring methods for parameters of steam turbine and its governing systems were proposed

according to the requirements of Q/GDW 748-2012 Guide for modeling and testing of generator's prime mover and governor.
