The simulation of the boiler-turbine power system based on VC++6.0

Abstract

An automatic control of the boiler-turbine system is the basic requirement of a modern power plant, and an important index of its technology. The research of the control strategies for boiler-turbine systems is meaningful in the view of both theory and practice. In order to calculate the output of the system according to its initial parameters and conditions, these control equations are solved on discrete meshes by the finite difference method. This also aims at simulating the boiler-turbine power system. This simulation has simple and beautiful interface coded by using of Microsoft VC++6.0. There are four modules: a calendar clock, the system operation and its input, and the output in main interface. The calendar clock shows real date and time. The system operation has three buttons: log, turn on and turn off. The input module is composed of a fuel switch, steam switch, water switch, and the corresponding status shown on the bar and the meter. When a hander inputs three correct groups of data in edit frames, and starts the simulated system, the data will be shown on the status bars and the meters. Furthermore, the data are changed randomly to the extent of the allowed value. The output part has the pressure and the manometer, the power and the power meter dynamo, and the highness of water and its status vision. After inputting every parameter and pressing the start button, a hander can simulate the system, and view log files recording the running situation of system.
