Problems solved by technology

[0003] However, although the DCS system is used to control the process control of the entire unit, the control algorithms for the controlled systems such as the water system, the fuel system, the wind and smoke system, and the denitrification system are single and backward, and it is impossible to realize real-time optimal control according to the state, and it is also impossible to realize the future After the key system is modeled, predictive control technology is used for the model, which reduces the control efficiency of the entire power plant and cannot achieve true integrated control

Embodiment Construction

[0038]The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] The preferred embodiment of an open integrated control platform for advanced algorithms is constructed. The advanced control integrated optimization platform project follows the three basic principles of integration, openness, and sustainability, that is, the external devices in the factory are integrated through a unified platform. , through the open Python development environment for secondary development of some algorithms, and further local optimization functions that will be added in the future can be integrated into the platform. The design of this platform can provide a foundation for the sustainable development of unit automatic control optimization, integrat...

Abstract

The invention discloses a power plant integrated control platform based on an advanced algorithm, which comprises a basic DCS platform, a communication acquisition interface, a model prediction subsystem, a controller, a data processing subsystem and an execution device, and is characterized in that the communication acquisition interface is connected with a data interface of the basic DCS platform and is used for data transmission; the model prediction model is used for establishing a plurality of prediction models and comprises a model prediction control module and an optimization module; the controller is connected with the model prediction subsystem and realizes prediction control optimization based on a prediction model of the model prediction subsystem; and the execution device is connected with the controller, and performs control action and / or parameter adjustment on the water system, the fuel system, the air and smoke system and the denitration system according to a control instruction sent by the controller.

Description

technical field [0001] The invention belongs to the technical field of power plant control systems, and in particular relates to an integrated control platform for power plants based on advanced algorithms. Background technique [0002] The existing power plant control platform is a conventional DCS system, that is, a distributed control system, which integrates the execution components and data acquisition functions, and integrates the two functions by connecting the PLC with the execution components and data acquisition. The DCS system is applied to coal power plants. Like the general DCS system, according to the operation logic of the power plant, according to the amount of various analog data, the control of various executive components is realized through the logic of the power plant operation. It is a kind of integrated system. Various data and correctly issue control instructions, analyze and judge various data to improve the working efficiency of the power plant. ...
