A data processing method and device for the reliability of environmental protection equipment in coal-fired power plants

Abstract

The invention provides a data processing method and device for the reliability of environmental protection equipment of a coal-fired power plant. The data processing method comprises the steps that a classification library including various classification items corresponding to all links influencing the reliability of coal-fired unit environmental protection equipment and values corresponding to the classification items, and a formula storage library including environmental protection equipment reliability calculation formulas are established in advance and are used for processing reliability data of the coal-fired unit environmental protection equipment multiple times; when an input instruction is received, values corresponding to multiple pieces of classification item information included in the input instruction respectively are taken from the classification library, and a classification item value table is generated; then, the environmental protection equipment reliability calculation formulas in the formula storage library are taken, values in the classification item value table are substituted into the environmental protection equipment reliability calculation formulas, and environmental protection equipment reliability parameters are worked out and then used for evaluating the reliability of different sets of coal-fired unit environmental protection equipment.

Description

technical field [0001] The invention relates to the technical field of reliability evaluation of environmental protection equipment in power station systems, and more specifically relates to a data processing method and device for the reliability of environmental protection equipment in coal-fired power plants. Background technique [0002] Coal-fired power plants are the main force in the development of national electric power. However, with the improvement of the country's environmental protection requirements for power plants, coal-fired power plants have a profound impact on the environment due to the large amount of pollution produced and concentrated sewage discharge caused by huge energy consumption. A series of transformations of various environmental protection equipment in coal-fired power plants are indispensable. [0003] The modified environmental protection equipment often leads to excessive discharge of pollutants in the flue gas of the unit due to its abnorma...

Problems solved by technology

[0003] The modified environmental protection equipment often leads to excessive discharge of pollutants in the flue gas of the unit due to its abnormal operation, which affects the economic benefits of the unit. The failure of the environmental protection equipment may even threaten the safe operation of the entire unit. Quantitative characterization of the degree of reliability

However, in the actual operation process, the reliability of different units cannot be quantified at this stage due to factors such as regional differences, different environmental protection standards, different installation capacities and types of the units themselves, and differences in environmental protection equipment between units with different capacities. It is also impossible to further evaluate the failure probability of environmental protection equipment, so there is an urgent need for a data processing method for the reliability of environmental protection equipment of different coal-fired units after transformation
