摘要

提出了1种采用美国ABB公司的Symphony DCS Composer组态语言与C语言联合编程的方法

采用C语言编制在线性能计算程序

Composer组态语言调用C语言程序

将DCS实时数据作为计算数据

计算得到单元机组能耗特性。C语言程序包含了基于IAPWS-IF97公式的焓熵值计算程序

集成一体化计算环境

无需调用其它程序

解决了DCS组态语言存在的对于复杂算法的局限性

实现了机组的在线性能计算。以某电厂1台660 MW机组为研究对象

对机组660 MW负荷下的煤耗进行了计算

计算结果误差在允许范围内

表明该在线计算方法可行。

Abstract

A joint programming method adopting Symphony DCS Composer configuration language and C language made from ABB Corp in USA has been put forward

adopting C language to draw up the on-line performance calculation programme

the Composer configuration language is used for calling the C language programme

taking the real-time data of DCS as the calculation data

the performance of energy cosumption can be calculated and obtained.The C language programme contains the calculation programmes of enthalpy and entropy values based on IAPWS-IF97 formula

creating an integrated calculation environment

it is unnecessary to call other programmes

resolving the limitations for complex algorithms existing in DCS configuration language

realizing the on-line performance calculation of units.Taking 60 MW unit no.2 in one power plant as the object of study

the coal consumption under unit load of 660 MW has been calculated

the error of calculated results is within an allowable range

showing the on-line calculation method is feasible.
