Description

Technical Field

[0001] The present invention relates to the technical field of gas engine control, and in particular to a gas engine MARK VIe control architecture. Background Art

[0002] In recent years, the LCI system equipment of the GE 9F gas turbine units put into operation in my country has been in operation for more than ten years. The gas turbine units are basically operated in a daily start-stop mode in the power grid dispatching. The LCI system has begun to show defects such as equipment aging and high failure rate, which seriously affects the safe operation of the gas turbine units. In addition, the gas turbine LCI and excitation system equipment are all imported equipment from GE. The purchase price of spare parts and equipment upgrades is high, and the supply cycle is long. Key technologies are blocked and not open, which is not conducive to the daily maintenance of gas turbine power plants and the safe operation requirements of units.

[0003] GE 9F gas turbine unit LCI, excitation system operation, control signals and MARK VIe control system all use the embedded EGD communication protocol (ethernet global data) (Ethernet Global Data Protocol) communication system connection method, which supports information sharing between multiple nodes based on the UPD / IP standard protocol. It is a non-international standard communication system protocol (as shown above Figure 1 As shown in the figure).

The localization transformation of the excitation system also has this problem.

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a structural schematic diagram of a MARK VIe control architecture of a gas turbine provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] To solve the above problems, see Figure 1 An embodiment of the present invention provides a gas turbine MARK VIe control architecture, including: a gas turbine MARK VIe control system 1, an excitation system 2, an LCI system 3 and a gas turbine MARK VIe communication switch 4.

[0026] The DI card port of the gas engine MARK VIe control system 1 is connected to the DI card port of the excitation system 2, and the DI card port of the gas engine MARK VIe control system 1 is connected to the DI card port of the LCI system 3; the DO card port of the gas engine MARK VIe control system 1 is connected to the DO card port of the excitation system 2, and the DO card port of the gas engine MARK VIe control system 1 is connected to the DO card port of the LCI system 3; the AI ​​card port of the gas engine MARK VIe control system 1 is connected to the AI ​​card port of the excitation system 2, and the AI ​​card port of the gas engine MARK VIe control system 1 is connected to the AI ​​card port of the LCI system 3; the AO card port of the gas engine MARK VIe control system 1 is connected to the AO card port of the excitation system 2, and the AO card port of the gas engine MARK VIe control system 1 is connected to the AO card port of the LCI system 3.

[0027] The communication end of the gas engine MARK VIe control system 1 is connected to the first communication end of the gas engine MARK VIe communication switch 4; the gas engine MARK VIe communication switch 4 is connected to the external MARK VIe communication system through the second communication end.

[0028] The above architecture uses DI (digital input), DO (digital output), AI (analog input), and AO (analog output) terminals for hard wiring connection, replacing the original EGD communication method (in the prior art, GE's LCI system 3 controls the EGD point signal and the two redundant communication switches of the MARK VIe control system, and GE's excitation system 2 controls the two network twisted pair cables for communication between the EGD point signal and the MARK VIe control system).

[0029] LCI system 3 and excitation system 2 participate in control by inputting input signals to the MARK VIe control system through the newly added DI and AI terminal cards. The technical barrier problem of the original EGD communication method is solved by hard wiring connection, making the localization transformation of LCI system 3 and excitation system 2 possible. Without adopting the EGD communication method, the original MARK VIe control logic of LCI and excitation system 2 can still be maintained through hard wiring connection, ensuring the stability and reliability of the system.

[0030] Wired connections are generally more reliable than EDG communication connections, especially in industrial environments. In addition, hard-wired connections are easier to troubleshoot and maintain, reducing maintenance costs. The use of hard-wired connections reduces dependence on original manufacturer support and technology blockades, and improves autonomous control capabilities.

[0031] The output signal of the gas turbine MARK VIe control system 1 can be sent to the LCI system 3 and the excitation system 2 through the DO and AO terminal output card boards, thereby realizing the control of the equipment.

[0032] By adopting the hard-wired connection method, the technical barriers of the original EGD communication method are effectively solved, while keeping the original control logic unchanged, improving the reliability and maintainability of the system. This is of great significance for the localization transformation and helps to improve the operating efficiency and safety of gas turbine power plants.

[0035] The communication end of the gas engine MARK VIe controller 10 is connected to the first communication end of the gas engine MARK VIe communication switch 4 .

[0036] Exemplarily, the excitation system 2 includes an excitation system controller 20 and an excitation system 2 control signal baseboard; the excitation system controller 20 is communicatively connected with the excitation system control signal baseboard 21;

[0037] The DI card port of the excitation system control signal baseboard 21 is connected to the DI card port of the gas turbine MARK VIe control system 1, and the DI card port of the excitation system control signal baseboard 21 is connected to the DI card port of the LCI system 3; the DO card port of the excitation system control signal baseboard 21 is connected to the DO card port of the gas turbine MARK VIe control system 1, and the DO card port of the excitation system control signal baseboard 21 is connected to the DO card port of the LCI system 3; the AI ​​card port of the excitation system control signal baseboard 21 is connected to the AI ​​card port of the gas turbine MARK VIe control system 1, and the AI ​​card port of the excitation system control signal baseboard 21 is connected to the AI ​​card port of the LCI system 3; the AO card port of the excitation system control signal baseboard 21 is connected to the AO card port of the gas turbine MARK VIe control system 1, and the AO card port of the excitation system control signal baseboard 21 is connected to the AO card port of the LCI system 3.

[0038] Exemplarily, the LCI system 3 includes an LCI system controller 30 and an LCI system 3 control signal backplane; the LCI system controller 30 is communicatively connected with the LCI system control signal backplane 31;

[0040] The existing LCI system 3 and excitation system 2 send the MARK VIe control system EGD point control signal prefix generally starts with L1(E1).G1.X (X represents the suffix signal point name), L1(E1).X (X represents the suffix signal point name), etc. plus the signal point name. The original GE company's LCI2 system sends the MARK VIe control system EGD point control signal prefix L2(E2).G2.X (X represents the suffix signal point name), L2(E2).X (X represents the suffix signal point name), etc. plus the signal point name. This is a unique technical communication signal method of EGD protocol communication. The modified LCI and excitation system 2 control signal points are changed to prefix L1(E1)_G1_X, L1_X (excitation system 2LCI1) or L2(E2)_G2_X, L2_X (excitation system 2LCI2) etc. with point names (Note: This format is used to distinguish the original EGD control signal points. The original EGD control signal points use L1(2) to indicate that the signal comes from the LCI1(2) control system, and E1(2) to indicate that the signal comes from the #1(2) excitation control system. The prefix L1(E1)_G1_ is mainly used to distinguish the original EGD signal point "L1(E1).G1."; X represents the suffix signal point name which is the same as the original EGD signal point name, mainly to facilitate the subsequent replacement of the original EGD signal without error, duplication, or missing signal points, and to distinguish it from the existing EGD control signal points, and to replace the EGD control signal points used by the original GE company with the new control signals of the localized transformation of the LCI system 3 and the excitation system 2 using the newly invented assignment method.

[0041] Exemplarily, referring to Table 1, the LCI system 3 sends a first DI input signal to the DI card port of the gas turbine MARK VIe control system 1 through the DI card port of the LCI system control signal baseboard 31, and the first DI input signal includes the LCI system 3 availability information and the system service information after the configuration is modified.

[0050] Exemplarily, referring to Table 3, the gas turbine MARK VIe control system 1 sends an AO output signal to the AO card port of the LCI system 3 through the AO card port of the gas turbine MARK VIe signal terminal board 11, and the AO output signal includes LCT speed reference information.

[0053] In this way, the MARK VIe control system of the gas turbine can send the necessary speed reference information to the LCI system in a timely manner, thereby ensuring that the LCI system can control the speed of the LCT according to the predetermined logic and requirements.

[0058] Exemplarily, before sending the second DI input signal, the sub-signals in the second DI input signal are renamed according to a preset rule.

[0059] Compared with the prior art, the MARK VIe control architecture of a gas turbine provided in an embodiment of the present invention adopts DI (digital input), DO (digital output), AI (analog input), and AO (analog output) terminals for hard wiring connection to replace the original EGD communication mode: the LCI system 3 and the excitation system 2 input the input signal to the MARK VIe control system through the newly added DI and AI terminal card boards to participate in the control. The output signal output by the MARK VIe control system is sent to the LCI system 3 and the excitation system 2 through the DO and AO terminal output card boards to realize the control of the equipment.

[0060] Without using EDG communication mode, the MARK VIe control system is given logic assignment, and the LCI system 3 and the excitation system 2 can be correctly interconnected and the control technology can keep the original MARK VIe control LCI and excitation system 2 logic unchanged.

[0061] The gas turbine MARK VIe control system 1 adds a terminal card mode, which can connect various signals from the domestic LCI system 3 and excitation system 2 control hard wiring with the MARK VIe control system signal, and use a special signal replacement assignment method to assign various signals from the domestic LCI and excitation system 2 control hard wiring to the original control logic, and cancel the original GE company LCI and excitation system 2EGD control signal points.

[0062] The gas turbine MARK VIe control system 1 adds the independently developed and innovative LCI control system logic communication to realize the normal startup and interconnection and mutual control technology of the LCI system 3 (including at least one LCI device).

[0063] In addition, the original gas turbine MARK VIe control system 1LCI and excitation control system HMI screens can be modified, the original EGD Ethernet communication reading and writing mode can be cancelled, and a new control screen can be adopted. The gas turbine MARK VIe control system 1 signal reading and writing mode can be adaptively changed according to the signal at the second communication port of the MARK VIe communication switch, so as to realize the normal startup, adjustment, monitoring and interconnection and mutual control technology of the domestically produced LCI and excitation control systems on the HMI screen.
