摘要

为了充分发挥基于一体化模型开发平台(IMMS)的火力发电厂厂级监控信息系统(SIS)上层应用功能

不仅要完成机组参数变量的计算

还需分析影响参数变量精度的因素。SIS输出数据精度受制于DCS数据源的测量和过程算法模型的计算

按照模型计算原理

综合考虑数据测量、引用频率等多种因素

对常规火电机组指标值的精度进行了等级划分。

Abstract

In order to give full play to applied functions in upper layer of supervisory information system(SIS) hased on integrated modular modelling software(SMMS)

not only the calculation of variables in panameters of units has to be fullfiled

the affecting factors of variables accuracy have also to be analysed.The accuracy of output data from SIS is restricted by measurement of DCS data source and calculation of process algorithm model.According to model calculation principle

the measurement of data has been conprehensively considered

and some factors like frequency etc.being introduced

the accuracy of index value for conventional thermal power units has been devided into grades.
