Coal-fired power plant coal yard refined management system and control method thereof

Abstract

The invention relates to a coal-fired power plant coal yard refined management system and a control method of the coal-fired power plant coal yard refined management system. The coal-fired power plant coal yard refined management system is characterized by comprising a laser disc coal instrument, an intelligent temperature monitoring meter, a metering device, a stacker-reclaimer, a data acquisition unit, a controller, a data server, an application server and a computer client side. The application server comprises a coal database management module, a real-time stock management module, a coal storage management module and a heat loss evaluation and control module. The control method is characterized by including the following steps that coal pile outline data points and digital signs in a coal yard field are acquired according to the laser disc coal instrument, and three-dimensional reconstruction of coal piles is completed based on a VC++ and OpenGL platform; when coal is transported to a factory, information is input to the coal database management module through an input port in the computer client side. According to the coal-fired power plant coal yard refined management system and the control method, the informatization and intelligentization method is adopted, information is quickly and accurately transmitted, and coal heat loss is reduced.

Description

technical field [0001] The invention relates to a refined management system and a control method for a coal yard in a coal-fired power plant, belonging to the field of fuel management in thermal power plants. Background technique [0002] As the grain of coal-fired power plants, coal provides a steady stream of power for the normal operation of the units, and its coal consumption costs account for 70% to 80% of the total power generation costs. Fuel management is to check and control the whole process of incoming, consumption, storage, quantity and quality of incoming coal. Doing a good job in fuel management can reduce the cost of fuel consumption and improve the economic benefits of the enterprise. Coal yard management is an important part of fuel management. Scientific and standardized management can effectively ensure the normal supply of coal in power plants, ensure the normal operation of units, and reduce the loss of coal storage. [0003] At present, in the manageme...
