Embodiment 1

[0023] A kind of environment-friendly thermal power unit system, its structure is as follows figure 1 Shown, comprise thermal power unit, sensor group, processor group, industrial computer 3 and monitoring server 5, sensor group is arranged in thermal power unit, the output end of sensor group connects the input end of processor group, and processor group passes industrial computer and The monitoring servers communicate with each other.

[0024] The sensor group is used to collect the key data of the thermal power unit, and transmit the collected data to the processor group. The sensor group includes a sulfide sensor 11 , a working condition sensor 12 , a coal quality sensor 13 and a circulating water temperature sensor 14 . The sulfide sensor 11 is installed on the sewage outlet of the thermal power unit to monitor the content of sulfur dioxide; the working condition sensor 12 is arranged in the thermal power unit to monitor whether the thermal power unit is in a stable work...

Embodiment 2

[0029] The structure of this embodiment is as figure 2 As shown, the difference from Embodiment 1 is that a load monitor 7 is also provided in the thermal power unit, and the load monitor is a dynamic load monitor. At the same time, the deep learning module of the monitoring server is provided with a load optimization unit 511 for processing the data reflected by the dynamic load monitor and forming an optimization parameter group related to load distribution.

[0030] In this embodiment, the deep learning module 51 performs fitness calculation according to the coal consumption-load curve, takes coal consumption as the objective function of load optimization distribution, and optimizes the model to achieve convergent coal consumption characteristic parameters through the iterative calculation of the parent and child generations , and set the upper and lower limits and balance constraints of each generator set, comprehensively consider the power generation requirements of each...

Embodiment 3

[0033] The structure of this embodiment is as image 3 As shown, the difference from Embodiment 2 is that the monitoring server is also connected to the application parent terminal 6 through the wireless network, and the application parent terminal is installed in the smart mobile device. The application control module 52 of the monitoring server is set in order to cooperate with the parent terminal of the application. The monitoring server can send the environmental protection curve and optimization parameters to the parent terminal of the application in a graphical manner. The status of the unit is adjusted in real time through the industrial computer.

[0034] The parent terminal of the application in this embodiment can realize real-time display, real-time alarm, and has the function of issuing adjustment parameter commands for certain parameters.

Description

technical field [0001] The invention relates to the technical field of thermal power generation equipment, and more specifically relates to an environment-friendly thermal power unit system. Background technique [0002] Thermal power generation is a form of power generation that utilizes the heat energy generated when combustibles are burned and converts it into electrical energy through a power generation device. At present, the main way people obtain electrical energy is thermal power generation. Thermal power plants are equipped with multiple sets of thermal power units for power generation operations. The pollutants emitted by them are mainly sulfur dioxide and other sulfides, which will cause great adverse effects on the environment. [0003] In recent years, with the gradual improvement of environmental protection requirements, in order to reduce the sulfur dioxide emissions of thermal power plants, many power plants have added flue gas desulfurization devices. Most ...
