F-level gas-steam combined cycle system self-starting and stopping control system and control method

Abstract

The invention discloses an F-level gas-steam combined cycle system self-starting and stopping control system and a control method thereof. The F-level gas-steam combined cycle system self-starting andstopping control system includes a monitoring background and a plurality of control cabinets; the monitoring background monitors the operation of all combined cycle systems through all the control cabinets; each control cabinet includes a power supply, a process control module, an input and output interface module and a communication module; the process control modules obtain operating parameterinformation of the controlled combined cycle systems through the input and output interface modules; the process control modules include system control units and a plurality of single equipment control units; and according to the operating parameter information of the controlled combined cycle systems, the control units control starting or stopping of each device in the corresponding subsystem through the single equipment control units so as to control a plurality of subsystems in the controlled combined cycle systems to automatically start or stop in sequence. According to the F-level gas-steam combined cycle system self-starting and stopping control system and the control method thereof, the labor intensity of operating personnel can be reduced, the consistency of the system start-stop process is improved, human error operations are reduced, the time of starting and stopping is shortened, and the safety of the unit operation is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control of electromechanical equipment, in particular to a self-start-stop control system and control method of an F-class gas-steam combined cycle system. Background technique [0002] Class F gas-steam combined cycle system is a relatively advanced energy system at present. It has the advantages of less waste discharge and faster load change rate, and because it realizes the cascade utilization of energy, it also has higher thermal efficiency. In the environment of increasing environmental pressure and high requirements for power grid peak regulation, its superiority has been well reflected, so it has developed rapidly. [0003] For the control of the F-level combined cycle system, the distributed control system is used at home and abroad at present, and the self-start-stop control is considered in the design stage. lucky situation. The combined cycle system mainly relies on manual operatio...

AI Technical Summary

Problems solved by technology

The combined cycle system mainly relies on manual operation, frequent operations in the start-stop phase, and the level of different operating personnel is uneven, and the experience in dealing with abnormal situations is different, which has potential safety hazards. Once misoperation occurs, the start-stop time will be extended, increasing Start-stop energy consumption, serious may cause damage to equipment and facilities

For some units currently in use with self-start-stop control systems, since the three-level structure of coordination level, subgroup level and equipment level is usually used in the design, the program is relatively complicated and prone to failures, and it is not easy for ordinary operators to grasp it deeply. After a failure, the automatic program is usually deactivated and manual operation is used, which is labor-intensive
