Realization of the thermal power station system based on component technologies

由于火电机组系统复杂,设备多,利用计算机组件编程技术开发出具有共同特性的设备组件,不仅可以解决复杂系统的实现,而且具有很好的继承性,便于系统的扩展。利用组件编程的思想开发了热力系统中各设备的通用组件模型。采用完成的组件能根据不同的机组热力系统结构,构成实际的热力系统图,设备的参数可以通过其内部定义的属性来读取或赋值,组件之间可以利用内部定义的成员方法来相互通信,从而完成机组的热经济性计算。组件思想大大提高了热经济性分析软件的开发速度,降低开发成本,使得软件开发扩展性强,灵活性高,代码重用率高。

A thermal power station is a very complicated system with a lot of equipment. Using the computer component programming technology, equipment components with common characteristics can be developed, which can not only realize the complicated system, but are convenient for system extension. In this paper, common component models for the equipment in the thermodynamic system were developed using component programming method. The diagram of the actual thermodynamic system can be constructed using those component models according to the detailed structure of the thermodynamic system of the power unit. The equipment parameters can be read and asgigned through their internal definition attribute, and the components can mutually communicate as members internally defined. Using the module method can greatly speed up the development of the software for thermal efficiency analysis and reduce the costs for software development. In addition, the software development shows a high extendibility and flexibility, and the code duplicate rate is high.
