Description

Technical Field

[0001] This invention relates to the field of gas turbine control technology, and in particular to a gas turbine MARK VIe control architecture. Background Technology

[0002] In recent years, the LCI system equipment of the GE 9F gas turbine units put into operation in my country has been running for more than ten years. The gas turbine units operate on a daily start-stop basis during grid dispatch, and the LCI system has begun to show defects such as equipment aging and high failure rates, seriously affecting the safe operation of the gas turbine units. Furthermore, the gas turbine LCI and excitation system equipment are all imported from GE, resulting in high procurement costs and long supply cycles for spare parts and equipment upgrades. Key technologies are also subject to embargoes and are not open to the public, which is detrimental to the daily maintenance and safe operation requirements of gas turbine power plants.

[0003] The GE 9F gas turbine unit's LCI, excitation system operation, control signals, and MARK VIe control system all use an embedded EGD communication protocol (Ethernet Global Data) for connection. This supports information sharing between multiple nodes based on the UPD / IP standard protocol, which is a non-international standard communication system protocol (as mentioned above). Figure 1 (As shown). Due to the lack of support and technology from GE in communication systems during the localization process, domestically produced equipment cannot connect with the original equipment's EGD-based communication system. Therefore, the localization of the LCI system cannot achieve signal connection with GE's MARK VIe control system. The localization of the excitation system faces the same problem; overcoming this technological barrier is essential for achieving localization of both the LCI and excitation systems.

Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the control architecture of a gas turbine MARK VIe according to an embodiment of the present invention. Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To resolve the above issues, please refer to [link / reference]. 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 turbine 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 turbine MARK VIe control system 1 is connected to the DI card port of the LCI system 3; the DO card port of the gas turbine 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 turbine MARK VIe control system 1 is connected to the DO card port of the LCI system 3; the AI ​​card port of the gas turbine 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 turbine MARK VIe control system 1 is connected to the AI ​​card port of the LCI system 3; the AO card port of the gas turbine 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 turbine MARK VIe control system 1 is connected to the AO card port of the LCI system 3.

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

[0028] The above architecture uses hard-wired connections for DI (digital input), DO (digital output), AI (analog input), and AO (analog output) terminals to replace the original EGD communication method (in the existing technology, GE's LCI system 3 controls the EGD point signals and the MARK VIe control system with two redundant communication switches, and GE's excitation system 2 controls the EGD point signals and the MARK VIe control system with two network twisted-pair cables).

[0029] LCI system 3 and excitation system 2 input input signals to the MARK VIe control system via newly added DI and AI terminal blocks to participate in control. The hard-wiring connection overcomes the technical barriers of the original EGD communication method, making the domestic modification of LCI system 3 and excitation system 2 possible. Even without using EGD communication, the hard-wiring connection maintains the original logic of MARK VIe controlling LCI and excitation system 2, ensuring system stability and reliability.

[0030] Hardwired connections are generally more reliable than EDG communication connections, especially in industrial environments. Furthermore, hardwired connections are easier to troubleshoot and maintain, reducing maintenance costs. Adopting hardwired connections reduces reliance on original equipment manufacturer (OEM) support and technological embargoes, enhancing self-reliance and controllability.

[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 cards, thereby realizing the control of the equipment.

[0032] By adopting a hard-wired connection method, the technical barriers of the original EGD communication method were effectively resolved, while maintaining the original control logic and improving the system's reliability and maintainability. This is of great significance for localization and will help improve the operating efficiency and safety of gas turbine power plants.

[0033] For example, the gas turbine MARK VIe control system 1 includes a gas turbine MARK VIe controller 10 and a gas turbine MARK VIe signal terminal board 11; the gas turbine MARK VIe controller 10 is communicatively connected to the gas turbine MARK VIe signal terminal board 11.

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

[0036] For example, the excitation system 2 includes an excitation system controller 20 and an excitation system 2 control signal base plate; the excitation system controller 20 is communicatively connected to the excitation system control signal base plate 21.

[0037] The DI card port of the excitation system control signal base plate 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 base plate 21 is connected to the DI card port of the LCI system 3; the DO card port of the excitation system control signal base plate 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 base plate 21 is connected to the DO card port of the LCI system 3; the AI ​​card port of the excitation system control signal base plate 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 base plate 21 is connected to the AI ​​card port of the LCI system 3; the AO card port of the excitation system control signal base plate 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 base plate 21 is connected to the AO card port of the LCI system 3.

[0038] For example, the LCI system 3 includes an LCI system controller 30 and an LCI system 3 control signal baseboard; the LCI system controller 30 is communicatively connected to the LCI system control signal baseboard 31.

[0039] The DI card port of the LCI system control signal base plate 31 is connected to the DI card port of the gas turbine MARK VIe control system 1, and the DI card port of the LCI system control signal base plate 31 is connected to the DI card port of the excitation system 2; the DO card port of the LCI system control signal base plate 31 is connected to the DO card port of the gas turbine MARK VIe control system 1, and the DO card port of the LCI system control signal base plate 31 is connected to the DO card port of the excitation system 2; the AI ​​card port of the LCI system control signal base plate 31 is connected to the AI ​​card port of the gas turbine MARK VIe control system 1, and the AI ​​card port of the LCI system control signal base plate 31 is connected to the AI ​​card port of the excitation system 2; the AO card port of the LCI system control signal base plate 31 is connected to the AO card port of the gas turbine MARK VIe control system 1, and the AO card port of the LCI system control signal base plate 31 is connected to the AO card port of the excitation system 2.

[0040] The existing LCI system 3 and excitation system 2 send control signals to the MARK VIe control system EGD point prefixes generally using prefixes such as L1(E1).G1.X (where X represents the suffix signal point name) or L1(E1).X (where X represents the suffix signal point name) followed by the signal point name. The original GE LCI2 system sent control signals to the MARK VIe control system EGD point prefixes such as L2(E2).G2.X (where X represents the suffix signal point name) or L2(E2).X (where X represents the suffix signal point name) followed by the signal point name. This is a unique signal communication method specific to the EGD protocol. The modified LCI and excitation system 2 control signal points are changed to prefixes L1(E1)_G1_X, L1_X(excitation system 2LCI1) or L2(E2)_G2_X, L2_X(excitation system 2LCI2) with point names added at the beginning (Note: This format is used to distinguish the original EGD point control signal points. The original EGD point control signal points used L1(2) to indicate that the signal is controlled by LCI1(2) and E1(2) to indicate that the signal is controlled by #1(2) excitation control system, prefixes L1(2)_G1_X, L1_X(excitation system 2LCI2)_G1_X, L1_X(excitation system 2LCI2)_G1_X, L1_X(excitation system 2LCI2)_G1_X, L1_X(excitation system 2LCI2)_G1_X, L1_X(excitation system 2LCI2)_G1_X(excitation system 2LCI2)_G1_X(excitation system 2LCI2)_G1_X(excitation system 2LCI2)_G1_X(excitation system 2LCI2)_G1_X(excitation system 2LCI1 ... L1(E1)_G1_ is mainly used to distinguish the original EGD signal point "L1(E1).G1."; X represents the suffix signal point name is the same as the original EGD signal point name, mainly to facilitate the replacement of the original EGD signal without errors, repetition, or omission of signal points (it has both distinction and connection), to distinguish it from the existing EGD control signal points, and to replace the original EGD control signal points used by GE with the new control signals of LCI system 3 and excitation system 2 that have been domestically modified.

[0041] For example, please refer 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. The first DI input signal includes LCI system 3 availability information and system service information after modification configuration.

[0042]

[0045] In this way, the LCI system can promptly report its current status and service information to the MARK VIe control system 1, thereby ensuring that the control system can make correct decisions based on the actual situation of the LCI system 3. This method improves the reliability and maintainability of the structure, helps to keep the original control logic unchanged, and solves the technical barriers of the original EGD communication method.

[0046] For example, please refer to Table 2. The gas turbine MARK VIe control system 1 sends a DO output signal to the DO card port of the LCI system 3 through the DO card port of the gas turbine MARK VIe signal terminal board 11. The DO output signal includes power-on request information, start-up selection information, LCI service confirmation information after configuration modification, remote signal reset information, and unit start-up information.

[0048] Table 2. DO Points for DO Output Signals

[0049] In this way, the gas turbine MARK VIe control system 1 can send necessary control commands and service information to the LCI system 3 in a timely manner, thereby ensuring that the LCI system 3 can operate according to the predetermined logic and requirements. This method improves the reliability and maintainability of the system, helps to keep the original control logic unchanged, and solves the technical barriers of the original EGD communication method.

[0050] For example, please refer 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. The AO output signal includes LCT speed reference information.

[0053] In this way, the gas turbine MARK VIe control system can send necessary speed reference information to the LCI system in a timely manner, thereby ensuring that the LCI system can control the LCT speed according to the predetermined logic and requirements. This method improves the system's reliability and maintainability, helps to keep the original control logic unchanged, and solves the technical barriers of the original EGD communication method.

[0054] For example, please refer to Table 4. The excitation system 2 sends a second DI input signal to the DI card port of the gas turbine MARK VIe control system 1 through the DI card port of the excitation system control signal base plate 21.

[0055]

[0056] Table 4. DI Point Table for the Second DI Input Signal

[0057] For example, before sending the first DI input signal, the sub-signals in the first DI input signal are renamed according to a preset rule.

[0058] For example, 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 to existing technologies, the MARK VIe control architecture for gas turbines provided in this embodiment of the invention replaces the original EGD communication method with hard-wiring connections using DI (digital input), DO (digital output), AI (analog input), and AO (analog output) terminals. The LCI system 3 and excitation system 2 input input signals to the MARK VIe control system via the newly added DI and AI terminal cards to participate in control. The output signals from the MARK VIe control system are sent to the LCI system 3 and excitation system 2 via the DO and AO terminal output cards to achieve equipment control.

[0060] Without using EDG communication, by assigning logic values ​​to the MARK VIe control system, LCI system 3 and excitation system 2 can correctly interconnect and control each other while maintaining the original MARK VIe control logic for LCI and excitation system 2.

[0061] The gas turbine MARK VIe control system 1 adds a terminal block card method, which can connect various signals from the hard-wired control of the domestic LCI system 3 and excitation system 2 to the MARK VIe control system signals. A special signal replacement assignment method is used to assign various signals from the hard-wired control of the domestic LCI and excitation system 2 to the original control logic, and the original GE LCI and excitation system 2 EGD control signal points are cancelled.

[0062] The gas turbine MARK VIe control system 1 adds independently developed and innovative LCI control system logic communication to realize the normal start-up and interconnection control technology of 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 screen can be modified, the original EGD Ethernet communication read / write method can be cancelled, and a new control screen can be adopted. The signal read / write method of the gas turbine MARK VIe control system 1 can be changed according to the signal adaptability at the second communication port of the MARK VIe communication switch, so as to realize the normal start-up, adjustment, monitoring and interconnection control technology of the domestic LCI and excitation control system on the HMI screen.

[0064] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
