Smart power plant control system and method

Abstract

A control system and method for a smart power plant, comprising: a temperature transmitter set arranged on the distribution area of ​​the furnace heating surface of the boiler in the power plant, a temperature transmitter set at the outlet of the boiler air preheater of the boiler in the power plant. The pressure transmitter, mobile communication module, controller and control terminal at the inlet of the boiler air preheater; the temperature transmitter group, temperature transmitter five, pressure transmitter and mobile communication module are all electrically connected to the controller ;Effectively avoid the centralized and unified management and control facilities for the temperature of the furnace heating surface distribution area of ​​the power plant boiler, the flue gas temperature at the outlet of the air preheater and the air pressure at the inlet of the air preheater in the prior art, and are used for power plant boiler control. The device information often causes the defect that the mobile communication network is blocked when the information is transmitted.

Description

technical field [0001] The invention relates to the technical field of power plant control, in particular to a control system and method for a smart power plant. Background technique [0002] Power plants generally refer to thermal power plants, and thermal power generation uses heat energy obtained from burning fuels (coal, petroleum and its products, natural gas, etc.) to generate electricity. There are two main types of generating units for thermal power generation: the use of boilers to generate high-temperature and high-pressure steam impulsively rotates the steam turbine to drive the generator to generate electricity, which is called a steam turbine generator set; the fuel enters the gas turbine to directly convert heat energy into mechanical energy to drive the generator to generate electricity, called gas turbine power generation unit. Thermal power plants usually refer to power plants dominated by steam turbine generator sets. Thermal power plants are mainly compo...

Problems solved by technology

[0005] However, because the sampling of each transmitter and the cycle of transmitting the transmitter information is short, the amount of information to be transmitted via the mobile communication network is always maintained on a very high amount, and the amount of information transmission is not small, which often makes mobile The communication network is blocked during the transmission of information

[0006] During the actual application period, the transmitter information collected by the transmitter in the power plant will mainly change slowly with the change of time. Only in the extreme state of the outside ground shaking severely, the transmitter information will fluctuate in the general state. Large states are rare; in addition, most of the transmitter information is located in the set index interval, and the transmitter information beyond the set index interval is also rare; that is to say, a small amount of information fluctuations are removed In the state of large amplitude and information error, in addition to the time-consuming transmission, the transmission of transmitter information in other states can allow a correspondingly higher time-consuming, so that there is no adverse effect on the power plant’s transmitter information control
