Embodiment 1

[0084] The present invention builds an optimization model based on actual production data, and can also jointly build an optimization model based on actual production data and data predicted by the forecast model, and provides an optimal operation plan through optimization calculations, reducing energy consumption and production costs for enterprises. Figure 2a and Figure 2c They are structural block diagrams of two implementations of an embodiment of the steam system operation optimization system, and the connections between the modules can be seen from the diagrams.

[0085] Depend on Figure 2a It can be seen that a steam system operation optimization system includes a real-time database, a relational database, an optimization model building module, an optimization model calculation module, and a human-machine interface module. The functions of each module are as follows:

[0086] The man-machine interface module is used as the communication interface between the operat...

Embodiment 2

[0207] On the basis of the above steam system operation optimization system, it can be expanded, for example, it can also include a steam production and consumption prediction module, and / or a working condition judgment module, and / or a scheduling system, etc., such as Figure 2b and 2d shown. In this case, it is necessary to supplement the above configuration parameters with corresponding parameters, for example, the following parameters can also be included (numbered consecutively with the above configuration parameters):

[0208] 4. Prediction model parameters of steam production and consumption: configured when there is a steam production and consumption prediction module.

[0209] The prediction model structure and prediction model parameters of steam production and consumption are determined according to the production process and production data, and the initial prediction model parameters need to be input manually.

Description

technical field [0001] The invention relates to steam systems in chemical industry, metallurgy and other fields, in particular to an operation optimization system and an operation optimization method for steam systems in these fields. Background technique [0002] Steam is an important energy medium in process industries such as chemical industry and metallurgy. Steam is produced through the combustion of energy media (usually coal, natural gas, and fuel oil). Steam can be used as a heat exchange or process production medium, and can also drive a generator to generate electricity or drive other equipment to do work. [0003] The steam system is a part of the public works of the enterprise. It consists of a steam pipe network and steam equipment to provide steam of various pressure levels for the production of the enterprise. figure 1 A schematic diagram of a simplified steam system is given. According to the steam pressure and temperature in the steam pipe network, the ste...
