Abstract

The invention relates to a power plant fuel intelligent management and control system and method based on a DCS. The fuel intelligent management and control system comprises an equipment operation control unit, an equipment operation data storage unit, a business logic control unit, a business data storage unit, a business execution unit and a supervision broadcasting unit. The business executionunit is controlled to execute automatic recognition, weighing, sampling, sample preparation, and sample saving and taking through the cooperation of the equipment operation control unit and the business logic control unit, equipment centralized monitoring and control of each link of fuel businesses of fuel in-warehouse can be realized, operation, production and fuels of thermal power generation enterprises are managed in a linkage and centralized manner, and the automation level of the enterprises is improved; the field work condition is improved, the work efficiency is improved, enterprise management risks are avoided, and the enterprise management cost is reduced; and a conventional fuel management business system and an equipment control system which are disperse are integrated to a unified platform so that the safety level of the system is improved.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a DCS-based power plant fuel intelligent management and control system and method. Background technique [0002] Fuel accounts for about 70% of the total cost of thermal power generation. If thermal power enterprises want to reduce their production and operating costs, they need to reform and innovate in the fuel management system, and make breakthroughs and innovations in the fuel management model. [0003] In domestic fuel intelligent construction, automatic identification system, sampling system, joint sample preparation system, pneumatic transmission system, storage and inspection system, etc., each system exists independently, and the control mode is the configuration mode of PLC + host computer, which mainly has the following shortcomings and disadvantages : [0004] 1) The feedback signal of some control equipment is missing, and the operating status of the local...
