【摘要】 为了配合火电厂热力系统的安全、经济运行，对其热力系统进行分析与模拟计算一直是众多热工工作者从事的工作。随着机组参数的提高和新技术、新设备的采用，热力系统也日趋复杂，这就需要一套热力系统的仿真建模软件能够实现动态建立模型并能够迅速进行热力系统安全与经济性计算，这样可以节省大量的人力、物力和时间。而计算机业的迅猛发展，以及面向对象编程思想的深入人心，为实现一套热力系统图形化动态建模系统提供了强有力的支持。因此，本论文的目的，就是要实现这样一个系统。本文采用VC++作为编程工具，在win98操作系统下开发出一个应用软件，在该软件中，成功的将热力系统进行了模块划分，使用面向对象的思想，将热力系统中每一个设备作为一个模块，而热力系统模型的建立，则是使用这些模块，将它们相互连接起来，形成网络图，然后使用图论的方法，对其进行研究、计算，最终成功的对动态组建的热力系统进行热经济性分析、计算。更多还原

【Abstract】 Many Heat Energy engineers always work to analyze and simulate compute to thermal system of power plant for supporting its security and economic performance operation. With parameters of steam turbine unit being risen and new technology and new equipment being adopted, thermal system have become more and more complex. As a result, it need a sort of software which can simulate and model thermal system to dynamic set up model and quickly analyze the security and economic performance of thermal system, which can save a lot of wealth and time. At the same time, the quick development of computer domain and Object-Oriented Programming(OOP) idea being widely used, strongly support to set up a graphic dynamic modeling of thermal system. Therefore, the aim of this paper is to realize a system that can do it. The paper using VC++ as tool of programming based Win98 OS(operate system) develops a set of application software in which it has succeed in partition thermal system into modules. The way of building model of thermal system is what connects all kinds of modules into network graphics, then analyze and compute by the way of graphical theory. At last using the software can successfully realize thermal economical performance analysis and compute of thermal system that dynamic set up.更多还原
