A method and system for intelligent decentralized control of thermal power units

Abstract

The invention discloses a large-capacity and high-parameter intelligent decentralized control method and system for a thermal power unit, comprising: a control device, the control device is internally provided with a control unit, a distributed balance control module, a control feedback module, an optimization control module, and a data storage module As well as the safety protection module, the control unit is used to issue control instructions to multiple thermal power units in the same field bus, so that each thermal power unit in the same field bus can be regulated in the first control mode or the second control mode; In the present invention, on the one hand, it is possible to regulate and control the operating conditions of the thermal power units, so that each thermal power unit in the same field bus can operate under the optimal operating conditions. The main engine of each thermal power unit and the physical property data of the corresponding auxiliary equipment are used to optimize and regulate the power part of each thermal power unit, so that the thermal power unit can achieve the optimal control target.

Description

technical field [0001] The invention relates to the technical field of decentralized control systems, in particular to an intelligent decentralized control method and system for large-capacity and high-parameter thermal power units. Background technique [0002] The thermal power unit is a unit that uses coal, oil or combustible gas as fuel to heat the water in the boiler to increase its temperature, and uses steam with a certain pressure to drive the gas turbine to generate electricity. The safety, environmental protection and stable operation of thermal power stations are one of the necessary conditions for supplying energy to the society and promoting social development. In recent years, with the development of my country's electric power industry, analog regulators are rarely used in each Used on thermal power units. [0003] At present, most of the performance calculations of large-scale thermal power generation units rely on manual calculations. However, the method of ...

Problems solved by technology

[0003] At present, most of the performance calculations of large-scale thermal power generation units rely on manual calculations. However, manual calculation of indicators has the disadvantages of long data collection time and low accuracy of collected data, which leads to the fact that the calculated indicator values ​​cannot be real-time and accurate. It is difficult to provide timely operation basis for the operators by displaying the performance of the equipment
