汽轮机热力性能计算软件设计与实现

摘要

In order to improve the efficiency of the power plant steam turbine unit and save energy,the steam turbine thermal system principle,thermal performance test procedures and heat rate calculation meth-od,and the modeled steam turbine thermal system based on ASME PTC6 -1996 testing procedures are researched.The paper develops the turbine thermal performance calculating software based on C /S architec-ture.Visual C ++6.0 is used as development environment to develop the system and SQL Server 2008 used as the back -end database to achieve query,modification and storage of data.The system includes appli-cation layer,business layer and data layer,and the specific modules includes parameter setting module, integrated performance calculation module,results correction modules and data query module.The software has advantages of high calculating accuracy,simple interface,practical value and convenient operation.%为了提高热力发电厂的经济效益和达到节能降耗的要求，研究了汽轮机原则性热力系统原理、热力性能试验过程和热耗率计算方法，基于 ASME PTC6—1996汽轮机试验规程对电厂原则性热力系统进行数学建模，开发了基于 C ／S 架构的汽轮机热力性能计算系统。系统采用 Visual C ＋＋6．0作为开发环境，使用 C ＋＋语言编写，实现汽轮机热力性能计算。SQL Server 2008作为后台数据库，实现数据的查询、修改及存储。整个系统包括应用层、业务层和数据层，具体功能模块包括参数设置模块、综合性能计算模块，结果修正模块及数据查询模块。软件计算精度较高，操作方便，界面简洁，具有实际应用价值。
