The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] It is understood that the terms "first", "second", etc. in the present disclosure are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or importance.

[0041] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results.

[0042] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0043] The two-to-one gas-steam combined cycle unit is an important component of a modern large-scale thermal power plant. It has the advantages of high efficiency, environmental protection, and flexibility. The unit is equipped with two gas turbines, two gas generators, a steam turbine, and a steam generator. The gas turbine and steam turbine drive the generators to generate electricity, thereby realizing efficient conversion and utilization of energy. The applicant found that during the actual operation of the unit, due to factors such as equipment aging and complex operating environment, gas turbine tripping failures often occur, which seriously affects the stable operation and economic benefits of the unit. Traditional fault recovery methods mostly rely on manual intervention, requiring operators to manually adjust and control according to the fault phenomenon, which is not only time-consuming and labor-intensive, but also has greater operational risks and uncertainties. Therefore, in response to the above problems, the applicant has proposed a gas turbine tripping fault self-recovery system and method. The gas turbine tripping fault self-recovery system and method provided by the present disclosure are described below.

[0044] Figure 1 is a block diagram of a gas turbine trip fault self-recovery system according to an exemplary embodiment. Figure 1 As shown, it is applied to a two-to-one operating unit, the two-to-one operating unit includes a first gas turbine, a second gas turbine, a first waste heat boiler, a second waste heat boiler and a steam turbine, and the gas turbine trip fault self-recovery system 100 includes: a state monitoring module 101 and a control module 102;

[0045] The state monitoring module 101 is used to monitor the trip state of the first gas turbine and the second gas turbine, and when the first gas turbine and / or the second gas turbine sends a trip signal, send the trip signal to the control module 102;

[0046] The control module 102 is used to control the operation of the first gas turbine, the second gas turbine, the first waste heat boiler, the second waste heat boiler and the steam turbine based on the trip signal.

[0047] Exemplarily, in a gas turbine trip fault self-recovery system, the state monitoring module 101 monitors the trip status of the first gas turbine and the second gas turbine in the two-to-one operating unit. When the first gas turbine and / or the second gas turbine trips, the state monitoring module obtains a trip signal issued by the first gas turbine and / or the second gas turbine, and sends the trip signal to the control module 102. The control module 102 controls the operation of the first gas turbine, the second gas turbine, the first waste heat boiler, the second waste heat boiler and the steam turbine based on the trip signal. For example, when the first gas turbine in the two-to-one operating unit trips and the second gas turbine does not trip, if the auxiliary steam system is the first gas turbine, the auxiliary steam system is automatically switched to the second waste heat boiler cold resteam source, and the pressure regulation system of the auxiliary steam system is switched to an automatic regulation state, which can realize automatic monitoring and recovery functions when a trip fault occurs in the unit gas turbine, thereby improving the unit operation efficiency and safety.

[0048] Through the above technical scheme, the tripping status of the first gas turbine and the second gas turbine is monitored by the status monitoring module, and the operation of the first gas turbine, the second gas turbine, the waste heat boiler, the second waste heat boiler and the steam turbine of the unit can be controlled based on the tripping signal sent by the gas turbine, so as to realize self-recovery of the gas turbine tripping fault, improve the operating efficiency and safety of the unit, and reduce the operation and maintenance cost.

[0049] Optionally, the control module is further used for:

[0050] When the first gas turbine sends a trip signal, the first waste heat boiler corresponding to the first gas turbine is controlled to perform interlock tripping.

[0051] Exemplarily, when a tripping fault occurs in the first gas turbine in the two-to-one operating unit, the first gas turbine sends a tripping signal and sends the tripping signal to the control module 102. The control module 102 controls the first waste heat boiler corresponding to the first gas turbine to perform an interlocking trip based on the tripping signal.

[0059] When the high-pressure drum is filled with water at a high position, the high-pressure feed water pump corresponding to the high-pressure drum is controlled to stop running;

[0060] When the high-pressure water supply of the medium-pressure drum is completed, the medium-pressure feedwater pump corresponding to the medium-pressure drum is controlled to stop running;

[0061] When the high-level water filling of the low-pressure drum is completed, the low-pressure economizer recirculation pump corresponding to the low-pressure drum is controlled to stop running, and the electric door and regulating valve at the inlet of the low-pressure economizer are closed.

[0062] Optionally, the control module 102 is further configured to:

When the steam turbine is switched to the automatic adjustment state, the function of switching to manual operation when the deviation between the adjusted quantity of each adjustment system and the set value is large is shielded to keep the system in an automatic state.

[0064] Through the above technical scheme, the tripping status of the first gas turbine and the second gas turbine is monitored by the status monitoring module, and the operation of the first gas turbine, the second gas turbine, the waste heat boiler, the second waste heat boiler and the steam turbine of the unit can be controlled based on the tripping signal sent by the gas turbine, so as to realize self-recovery of the gas turbine tripping fault, improve the operating efficiency and safety of the unit, and reduce the operation and maintenance cost.
