Description

Technical Field

[0001] This invention relates to the field of industrial automatic control technology, and in particular to a functional group control system suitable for automatic start-stop. Background Technology

[0002] In recent years, with the adjustment of the national energy structure and the increasing environmental emission requirements, gas turbines and their combined cycle units have become a direction for the development of clean energy in the power system. To adapt to the frequent start-ups and shutdowns of gas-steam combined cycle units, improve the accuracy and standardization of unit start-ups and shutdowns, reduce the workload of operators, shorten start-up and shutdown times, and improve the overall automation level of the units, the implementation of Automatic Plant Start-up and Shutdown System (APS) has become an inevitable trend.

[0003] The automatic start-stop control system adopts a pyramid-shaped hierarchical structure, generally divided into four layers: unit control level, functional group control level, functional subgroup control level, and equipment drive control level. The functional group control level is a crucial layer of the automatic start-stop control system. Functional group operation can be automatic or manual. In automatic mode, it receives control commands from the unit control level or the same functional group level. Based on the operating conditions of the corresponding system, it issues commands to the next level of control functional subgroups, automatic control systems, and / or equipment drives according to a predetermined program to complete the start-up, shutdown, and maintenance of process parameters for a specific process system, thus realizing the start-up and shutdown control program within the functional group.
