Intelligent decentralized control method and system for high-capacity and high-parameter thermal power generating unit

Abstract

The invention discloses an intelligent decentralized control method and system for a high-capacity high-parameter thermal power generating unit. The system comprises a control device which is internally provided with a control part, a decentralized balance control module, a regulation and control feedback module, an optimization control module, a data storage module, and a safety protection module, wherein the control part is used for sending a control instruction to a plurality of fire motor units in the same fieldbus, so each fire motor unit in the same fieldbus is regulated and controlled in a first regulation and control mode or a second regulation and control mode; according to the method, on one hand, the operation condition of the thermal power generating unit can be regulated and controlled, so each fire engine unit in the same fieldbus can operate under the optimal operation condition, and on the other hand, the physical property data of the main engine and the corresponding auxiliary engine equipment of each fire engine unit in the same fieldbus are collected; and the power part of each fire power unit is optimized and regulated, so the thermal power generating unit achieves 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
