  The dialogue processing unit 141 acquires the plant data acquired by the input / output unit 11 from the gas turbine control device 2 and displays the plant data on the information presentation unit 12.

  Further, the input unit 13 receives a plurality of attributes shown in FIG. 4 from the operator, and notifies the dialog processing unit 141 of the received plurality of attributes.

  FIG. 4 is a table showing an example of a plurality of attributes. As shown in FIG. 4, when the attribute is an operation type, the operator designates activation or deactivation as the value. When the attribute is the target load, as the value, in the case of activation, the target load from the central power supply command station is designated by the operator.

  When the attribute is the target time, the value is specified by the operator as the parallel target time of the steam turbine (ST) and gas turbine (GT) when starting, and when the engine is stopped, the stop completion target time is specified by the operator Is done. This parallel target time is the power transmission start target time at which power transmission from the multi-axis combine side cycle power plant to the system is started. The stop completion target time is a power transmission stop target time for stopping power transmission from the multi-axis combine side cycle power plant to the system.

  When the attribute is component, the value is the number of starting gas turbines (GT) or the configuration of the plant after starting up by the operator in the case of starting, and the number of starting gas turbines (GT) after the stopping operation in the case of stopping. Alternatively, the configuration after the stop is designated by the operator.

  When the attribute is an order, the value is designated by the operator as the value in the case of start-up, and the order of gas turbine (GT) stop is designated by the operator in the case of stop.

  When the operation type notified from the input unit 13 is activated, the PTN numbering processing unit 142 applies the component and order (that is, the gas turbine GT activation order) notified from the input unit 13 to the table 701 shown in FIG. Then, the corresponding PTN number is acquired. This component includes information indicating the number of gas turbine activations.

As will be described later, the gas turbine control device 2 activates the gas turbine 3 with the control content corresponding to the operation control signal indicating the PTN number. Or stop.

  As described above, the control unit 14 controls the operation of the gas turbine according to the start order or the stop order received by the input unit 13 and the target number of gas turbines in the operating state when the start is completed or after the stop operation. An operation control signal is generated for each gas turbine. The operation control signal includes the gas turbine to be started or stopped, the start order or stop order of the gas turbine to be started or stopped, and the target number of gas turbines that are in the operating state after the start operation or after the stop operation. Is specified.

  The PTN number assignment processing unit 142 notifies the schedule calculation processing unit 143 of the PTN number. Further, the PTN number numbering processing unit 142 notifies the schedule calculation processing unit 143 of a calculation execution request.

  FIG. 5 is a table used to determine the PTN number at the time of activation. As shown in FIG. 5, in the table 701, PTN numbers assigned to the respective gas turbines are determined for combinations of components and orders. For example, if the component is a 3ON1 configuration and the order is ABC, that is, GT (A), GT (B), GT (C) is activated, the PTN number is “KA13” for GT (A). "become.

  Here, the PTN number at the time of activation is determined according to the number system shown in FIG. FIG. 6 is a diagram showing a numbering system 501 of PTN numbers at the time of activation. As shown in FIG. 6, “K” representing start-up is assigned to the first character, and information (here, alphabets as an example) identifying the gas turbine to be started is assigned to the second character. The 3rd character shows the starting order of the gas turbine used as starting object. The fourth character is a number that identifies the plant configuration after the start-up operation.

  For example, as shown in FIG. 6, when the PTN number is “KB23”, GT (B) is activated second, indicating that there are three gas turbines in the operating state after the activation operation. This means that the PTN number “KB23” starts GT (B) secondly while starting the three gas turbines.

  FIG. 7 is a table used to determine the PTN number at the time of stop. As shown in FIG. 7, in the table 801, PTN numbers assigned to the respective gas turbines are determined for combinations of components and orders. For example, when the component is a configuration of 0ON0 and the order is ABC, that is, the stop order of GT (A), GT (B), and GT (C), the PTN number is “TA10” for GT (A). "become.

  Here, the PTN number at the time of stopping is determined according to the numbering system shown in FIG. FIG. 8 is a diagram showing a numbering system 601 of PTN numbers at the time of stopping. As shown in FIG. 8, “T” representing a stop is assigned to the first character, and information (here, alphabets as an example) identifying the gas turbine to be stopped is assigned to the second character. The third character indicates the stop order of the gas turbine to be stopped. The fourth character is a number for identifying the plant configuration after the stop operation.

  For example, as shown in FIG. 8, when the PTN number is “TC21”, GT (C) stops second, indicating that there is one gas turbine in the operating state after the stop operation. This means that the PTN number “TC21” stops GT (B) second while stopping two gas turbines.

  The schedule calculation processing unit 143 determines a schedule for starting or stopping at least one of the plurality of gas turbines using the parallel target time or the stop completion target time received by the input unit 13. The schedule calculation processing unit 143 stores schedule data indicating the determined schedule in the schedule data unit 15.

  The automation processing unit 144 refers to the determined schedule, and when the time that is a specified time before the start start time or the stop start time of the specific gas turbine among the plurality of gas turbines comes to the specific gas turbine, The information presentation unit 12 is caused to present information that prompts activation or deactivation. Thereby, the operator of the multi-shaft combined cycle power plant can grasp that the start start time or the stop start time is near. For this reason, when the start start time or stop start time is reached, the operator inputs the start instruction or stop instruction for the plant using the input unit 13 of the control device 1.

  When the input unit 13 receives the start instruction or the stop instruction, the automation processing unit 144 is determined for the gas turbine control device 2 that controls the gas turbine to be started or stopped in addition to the start instruction or the stop instruction. The operation control signal indicating the PTN number is transmitted from the input / output unit 11 to the gas turbine control device 2. As a result, the gas turbine control device 2 starts or stops the gas turbine 3 to be started or stopped with the control content corresponding to the received operation control signal.

  In this manner, the control unit 14 sends the operation control signal to the corresponding gas turbine control device, and the input / output unit 11 performs the start or stop of the gas turbine with the control content according to the operation control signal. To send from.

<Details of processing of dialogue processing unit 141>
Next, details of the processing of the dialogue processing unit 141 will be described. FIG. 9 is a diagram illustrating a configuration of the dialogue processing unit 141 according to the first embodiment. As shown in FIG. 9, the dialogue processing unit 141 includes a schedule calculation menu display unit 251, an activation schedule setting screen display unit 252, an activation schedule attribute setting unit 253, an activation schedule attribute notification unit 254, and an attribute storage unit 401. And an activation schedule setting screen storage unit 402.

  The schedule calculation menu display unit 251 causes the information presenting unit 12 to display a dialog setting screen corresponding to the start or stop operation.

  The activation schedule setting screen storage unit 402 stores activation schedule setting screen information that is information for displaying the activation schedule setting screen.

  When activation is selected on the dialog setting screen described above, the activation schedule setting screen display unit 252 reads activation schedule setting screen information from the activation schedule setting screen storage unit 402 and displays the activation schedule setting screen on the information presentation unit 12. Let

  The start schedule attribute setting unit 253 prompts the operator to select and set the number and start order of the gas turbine, the parallel target time of the steam turbine and the gas turbine, and the like. The activation schedule attribute setting unit 253 stores the attribute designated by the operator in the attribute storage unit 401.

  The activation schedule setting screen display unit 254 reads the attribute designated by the operator from the attribute storage unit 401 and notifies the PTN number numbering processing unit 142 of the read attribute.

  Further, the dialogue processing unit 141 includes a stop schedule setting screen display unit 255, a stop schedule attribute setting unit 256, a stop schedule attribute notification unit 257, and a stop schedule setting screen storage unit 403.

  Similarly, during the stop operation, the stop schedule setting screen storage unit 403 stores stop schedule setting screen information that is information for displaying the stop schedule setting screen.

  When the stop is selected on the above-described dialog setting screen, the stop schedule setting screen display unit 255 reads the stop schedule setting screen information from the stop schedule setting screen storage unit 403, and the information presentation unit 12 displays this stop schedule setting screen information. To display.

  The stop schedule setting screen display unit 256 prompts the operator to select and set the number of gas turbine operations and stop order after the stop operation, the target time for completing the stop, and the like. The stop schedule setting screen display unit 256 stores the attribute designated by the operator in the attribute storage unit 401.

  The stop schedule setting screen display unit 257 reads the attribute designated by the operator from the attribute storage unit 401 and notifies the PTN number numbering processing unit 142 of the read attribute.

  As a result, when starting or stopping a plurality of gas turbines, each gas turbine control can be performed without any increase or decrease in the number of operation of the gas turbine, such as additional startup when at least one gas turbine has been started. The device 2 can be notified.

<Details of processing of the PTN numbering processing unit 142>
Next, processing of the PTN number numbering processing unit 142 will be described. FIG. 10 is a diagram illustrating a configuration of the PTN number assignment processing unit 142 according to the first embodiment.

  As shown in FIG. 10, the PTN number numbering processing unit 142 includes an attribute input unit 301, a startup PTN number creation unit 302, a startup PTN number determination unit 303, a startup PTN number notification unit 304, and a startup PTN number determination. A condition information storage unit 305.

  Further, the PTN number assignment processing unit 142 includes a stop PTN number creation unit 306, a stop PTN number determination unit 307, a stop PTN number notification unit 308, a stop PTN number determination condition information storage unit 309, and a PTN number abnormality notification. Unit 310.

  The attribute input unit 301 acquires a plurality of attributes as illustrated in FIG. 4 from the dialogue processing unit 141.

  The activation PTN number determination condition information storage unit 305 stores a table 701 as shown in FIG.

  The startup PTN number creation unit 302 refers to the startup PTN number determination condition information storage unit 305 when the value of the operation type among the attributes acquired by the attribute input unit 301 is startup, and the gas turbine acquired by the attribute input unit 301 A PTN number corresponding to the startup number and the gas turbine startup order is determined.

  The activation PTN number determination unit 303 determines whether or not the PTN number determined by the activation PTN number creation unit 302 is normal using the activation PTN number determination formula 901 illustrated in FIG. FIG. 11 is an example of the activation PTN number determination formula 901. When the activation PTN number determination formula 901 shown in FIG. 11 is applied, it is abnormal, and when it is not applied, it is normal.

  When the activation PTN number determination unit 303 determines that the PTN number is normal, the activation PTN number notification unit 304 notifies the schedule calculation processing unit 143 of the PTN number.

  Next, a specific determination example in the activation PTN number determination unit 303 will be described below from several selection patterns assumed for the attribute.

  Judgment example 1 is a case where it is desired to change from a gas turbine all-station stop state to a 3ON1 state. In this case, the operator selects “ABC” as the order and “3” (that is, the configuration of 3ON1) as the component as the attribute. When this order and component are applied to the table 701 of FIG. 5, the PTN number for GT (A) is KA13, the PTN number for GT (B) is KB23, and the PTN number for GT (C) is KC33. In this case, there is no problem in selecting the operator, and the numbering result of the PTN number is normal.

  In the determination example 2, in the 1ON1 state in which only the GT (C) has already been activated, the GT (A) is additionally activated and the 2ON1 configuration is to be started. Note that GT (B) is in a stopped state. Here, the operator selects “CAB” as the order and “2” (that is, the configuration of 2ON1) as the component. When this order and component are applied to the table 701 in FIG. 5, the PTN number for GT (A) is KA22, and the PTN number for GT (C) is KC12. On the other hand, GT (B) does not need to be activated in the 2ON1 configuration, and no PTN number is assigned. In this case, the numbering result of the PTN number is normal.

  Next, an example of abnormal numbering will be described.

  In the determination example 3, GT (A) is additionally activated from the 1ON1 state where activation of only GT (C) is completed, and the 2ON1 state is to be started. Note that GT (B) is in a stopped state. Here, it is assumed that the operator selects “2” (ie, 2ON1 configuration) as the component, but selects “ACB” by mistake in the order.

When this order and component are applied to the table 701 in FIG. 5, KA12 is obtained as the PTN number for GT (A) and KC22 is obtained as the PTN number for GT (C). On the other hand, GT (B) does not need to be activated in the 2ON1 configuration, and no PTN number is assigned.
In this case, the first stage condition of the activation PTN number determination formula 901 is applied. That is, although the GT (C) whose order is later is completed, and the GT (A) whose order is earlier is not yet activated, there is a contradiction in numbering.

  Therefore, the activation PTN number determination unit 303 determines that the numbering is abnormal, and notifies the dialog processing unit 141 of the abnormality via the PTN number abnormality notification unit 310. As described above, when the activation PTN number determination unit 303 determines that there is an abnormality, the PTN number abnormality notification unit 310 notifies the interaction processing unit 141 of the abnormality.

  The determination example 4 is a case where GT (A) is additionally activated from the 1ON1 state where activation of only GT (C) is completed, and the 2ON1 state is to be started. Note that GT (B) is in a stopped state. Here, it is assumed that the operator selects “2” (ie, 2ON1 configuration) as the component, but selects the order “ABC” by mistake.

  When this order and component are applied to the table 701 in FIG. 5, KA12 is obtained as the PTN number for GT (A), and KB22 is obtained as the PTN number for GT (B). On the other hand, GT (C) does not need to be activated in the 2ON1 configuration, and no PTN number is assigned.

  In this case, as in the determination example 3, there is a contradiction that “the start order GT (A) is not in the start completion state even though the start order GT (C) has started starting”. Has occurred. Therefore, the activation PTN number determination unit 303 determines that the numbering is abnormal, and notifies the dialog processing unit 141 of the abnormality via the PTN number abnormality notification unit 310.

  The stop PTN number determination condition information storage unit 309 stores a table 801 as shown in FIG.

  The stop PTN number creation unit 306 refers to the stop PTN number determination condition information storage unit 309 when the operation type value of the attributes acquired by the attribute input unit 301 is stopped, and the gas turbine acquired by the attribute input unit 301 A PTN number corresponding to the number of stops and the gas turbine stop order is determined.

  The stop PTN number determination unit 307 determines whether or not the PTN number determined by the stop PTN number creation unit 306 is normal using the stop PTN number determination formula 902 shown in FIG. FIG. 12 is an example of the stop PTN number determination formula 902. When the stop PTN number determination formula 902 shown in FIG. 12 is applied, it is abnormal, and when it is not applied, it is normal.

  When the stop PTN number determination unit 307 determines that the PTN number is normal, the stop PTN number notification unit 308 notifies the schedule calculation processing unit 143 of the PTN number.

  Next, specific determination examples in the stop PTN number determination unit 307 will be described below based on several selection patterns assumed to have attributes.

  Judgment example 1 is a case where a gas turbine all-unit operation state is changed to a all-unit stop state (0ON0). In this case, the operator selects “CBA” as the order and “0” (that is, the configuration of 0ON0) as the component. When this order and component are applied to the table 801 in FIG. 7, TA30 is obtained as the PTN number for GT (A), TB20 is obtained as the PTN number for GT (B), and TC10 is obtained as the PTN number for GT (C). In this case, there is no problem in selecting the operator, and the numbering is normal.

  Judgment example 2 is a case where GT (B) is stopped in the 2ON1 state in which GT (B) and GT (C) are operating, and a 1ON1 configuration is to be made. Note that GT (A) is in a stopped state. Here, the operator selects “ABC” as the order and “1” (that is, the configuration of 1ON1) as the component. When this order and component are applied to the table 801 of FIG. 7, TA11 is obtained as the PTN number of GT (A), and TB21 is obtained as the PTN number of GT (B). On the other hand, GT (C) does not need to be stopped and no stop PTN number is assigned. In this case, there is no problem in selecting the operator, and the numbering is normal.

  Next, an example of numbering abnormality will be described.

  The determination example 3 is a case where GT (B) is stopped from the 2ON1 state in which GT (B) and GT (C) are operating, and the 1ON1 state is desired. Note that GT (A) is in a stopped state. Here, it is assumed that the operator selects “1” (that is, 1ON1 configuration) as the component, but accidentally selects “BAC” for the order. When this order and component are applied to the table 801 of FIG. 7, TB11 is obtained as the PTN number of GT (B), and TA21 is obtained as the PTN number of GT (A). On the other hand, GT (C) does not need to be stopped, and no stop PTN number is assigned.

  In this case, the condition of the first stage of the stop PTN number determination formula 902 is applied. That is, since the GT (B) whose order is earlier is not in a stopped state, the GT (A) whose order is later is completed, and there is a contradiction in numbering.

  For this reason, the stop PTN number determination unit 307 determines that the numbering is abnormal, and notifies the dialog processing unit 141 of the abnormality via the PTN number abnormality notification unit 310.

  Judgment example 4 is a case where GT (B) is stopped from the 2ON1 state in which GT (B) and GT (C) are operating, and the 1ON1 state is to be changed. Note that GT (A) is in a stopped state. Here, it is assumed that the operator selects “1” (that is, 1ON1 configuration) as the component, but accidentally selects “BCA” for the order. When this order and component are applied to the table 801 of FIG. 7, TB11 is obtained as the PTN number of GT (B), and KB21 is obtained as the PTN number of GT (C). On the other hand, GT (A) does not need to be stopped and no stop PTN number is assigned.

  In this case, in the same way as in the determination example 3, the GT (B) whose order is the starting GT (B) is not completely stopped, but the GT (A) whose order is the starting GT (A) has been completely stopped. Yes. For this reason, the stop PTN number determination unit 307 determines that the numbering is abnormal, and notifies the dialog processing unit 141 of the abnormality via the PTN number abnormality notification unit 310.

  As described above, in the multi-shaft combined cycle power plant, the PTN number numbering processing unit 142 can determine the PTN number according to the increase or decrease in the number of operating gas turbines after the one steam turbine 7 is arranged in parallel. .

<Details of processing of schedule calculation processing unit 143>
Next, details of schedule calculation processing in the schedule calculation processing unit 143 will be described.

  Start-up schedule calculation refers to when the start-up operation of the plant should start when the parallel target time, which is the time to start transmitting power from the multi-axis combined cycle power plant to the grid, is set. Is obtained by calculation based on the above. In addition, when calculating the startup schedule, parameters necessary for the startup operation (turbine acceleration rate, etc.) are also obtained by calculation. These parameters are notified to each gas turbine controller so that the gas turbine can be properly started.

  On the other hand, the stop schedule calculation is based on the calculation of when to start reducing the plant output when the stop completion target time, which is the time to stop power transmission from the multi-shaft combined cycle power plant to the grid, is set. It is what you want.

  A multi-shaft combined cycle power plant is composed of a plurality of systems such as a water and steam system, a fuel system, a ventilation system, and a cooling water system, and each system is provided with a pump, a heat exchanger, a valve, and the like. .

  At startup, each system is operated in parallel in order. Since the required time varies depending on the stop state of the plant, it is impossible to calculate how many hours before the target time should be started.

  Therefore, the schedule calculation processing unit 143 divides the startup process into several stages (called breakpoints), and calculates the operation and required time of each system performed in that stage using the stop condition and stop time as parameters. The time required for the stage is set to the maximum time among the parallel operations. The schedule calculation processing unit 143 obtains the total startup required time by adding the same amount for the stages.

  The longer the plant stop time (the time from disconnection to parallel), the longer the time required for each stage. This is because the longer the stop time, the lower the temperature of the boiler or turbine metal and the lower the temperature, so that it takes time to increase the temperature at startup.

  Therefore, the schedule calculation processing unit 143 first calculates the total activation required time under the condition that the activation is started immediately at the time when the calculation is requested.

  If the first time obtained by adding all the required startup times calculated to the current time is earlier than the parallel target time, a difference occurs between the first time and the parallel target time. Therefore, the schedule calculation processing unit 143 next updates the activation start time to a time delayed by this difference time (= parallel target time−first time), and obtains the total activation required time again. The schedule calculation processing unit 143 determines the delayed activation start time as the final activation start time when the calculation time obtained by adding the total activation time to the delayed activation start time and the parallel target time fall within a predetermined time difference. To do.

  On the other hand, the schedule calculation processing unit 143 is activated when the calculation time obtained by adding the total activation required time to the delayed activation start time and the parallel target time do not fall within a predetermined time difference, or when the calculation time exceeds the parallel target time. The start time is further updated to a time earlier by this difference time (= calculation time−parallel target time). On the other hand, if the calculation time is earlier than the parallel target time, the start time is changed to the time of this difference (= It is further updated to a time delayed by (parallel target time−calculation time). And the schedule calculation process part 143 calculates | requires all the starting required time again.

  The schedule calculation processing unit 143 obtains the activation start time by repeating the above-described calculation until the calculation time and the parallel target time fall within a predetermined time difference.

  Further, the schedule calculation processing unit 143 obtains the stop start time by the same method as that for calculating the start start time described above.

  FIG. 13 is a diagram illustrating a configuration of the gas turbine control device 2 according to the first embodiment. As shown in FIG. 13, the gas turbine control device 2 includes an input / output unit 21, a storage unit 22, a RAM 23, a CPU 24, and an output unit 25.

  The input / output unit 21 is connected to the control device 1. For example, the input / output unit 21 receives a command for starting or stopping the gas turbine and an operation control signal from the control device 1.

  The storage unit 22 stores various programs.

  The RAM 23 primarily stores data.

  The CPU 24 functions as the control unit 241 by reading the program from the storage unit 22 into the RAM 23 and executing it.

  When the input / output unit 21 receives an instruction to start or stop the gas turbine, the control unit 241 starts or stops the gas turbine 3 with the control content corresponding to the operation control signal received by the input / output unit 21. Specifically, for example, the control unit 241 outputs a control signal from the output unit 25 to the gas turbine 3 so that the gas turbine 3 is started or stopped with the control content according to the operation control signal.

  The operation | movement at the time of starting of the multi-shaft combined cycle power plant in 1st Embodiment which has the above structures is demonstrated using FIG. Since the operation at the time of stop is the same as the operation at the time of start-up, the description thereof is omitted.

  FIG. 14 is a flowchart illustrating an example of processing at the time of starting the plant in the first embodiment.

  (Step S101) First, the input unit 13 receives an input of attributes at the time of plant start-up operation from the operator.

  (Step S102) Next, the control unit 14 determines the PTN number using the operation type, component and order received by the input unit 13.

  (Step S103) Next, the control unit 14 calculates an operation schedule up to the activation target time using the parallel target time received by the input unit 13.

  (Step S104) Next, the control unit 14 determines whether or not a time that is a specified time before the start time of the start-up gas turbine has come. If the time is not a predetermined time before the start time of the gas turbine to be started, the control unit 14 stands by as it is.

  (Step S105) In Step S104, when it is determined that the time before the activation time of the gas turbine to be activated has reached a specified time, the control unit 14 provides information for prompting activation of the gas turbine to be activated as an information presentation unit. 12 to present.

  (Step S106) Next, the control part 14 determines whether the input part 13 received the starting instruction | indication of the gas turbine of starting object. When the input unit 13 has not received a start instruction for the gas turbine to be started, the control unit 14 stands by as it is.

  (Step S107) When it is determined in step S107 that the input unit 13 has received a start instruction for the gas turbine to be started, the control unit 14 sends an operation control signal indicating the PTN number and a start command to the gas turbine to be started. Is transmitted to the gas turbine control device 2 for controlling.

  (Step S108) Next, the control unit 14 determines whether there is a gas turbine to be activated later. When there is a gas turbine to be activated later, the control unit 14 performs the process of step S104 with the gas turbine to be activated later as a gas turbine to be activated.

  (Step S201) The gas turbine control device 2 that controls the gas turbine to be activated receives the operation control signal and the activation command.

  (Step S202) The gas turbine control device 2 that controls the gas turbine to be activated executes activation of the gas turbine with the control content corresponding to the received operation control signal.

  As described above, in the first embodiment, the input unit 13 receives the start order or stop order of each gas turbine and the target number of gas turbines that are in an operating state after the start operation or after the stop operation.

  The control unit 14 is an operation control signal for controlling the operation of the gas turbine in accordance with the start order or stop order received by the input unit 13 and the target number of gas turbines in the operating state after the start operation or after the stop operation. For each gas turbine.

  The control unit 14 causes the operation control signal to be transmitted from the input / output unit 11 to the corresponding gas turbine control device, which is a gas turbine control device 2 that starts or stops the gas turbine with the control content according to the operation control signal. .

  As a result, the gas turbine control device 2 starts the gas turbine 3 to be controlled with the control content corresponding to the starting order of the gas turbine 3 and the target number of the gas turbines 3 in the operating state after the starting operation. Can do. Similarly, the gas turbine control device 2 stops the gas turbine 3 to be controlled with the control content corresponding to the stop order of the gas turbine 3 and the target number of the gas turbines 3 in the operating state after the stop operation. Can do.

  For this reason, the operator simply specifies the start order or stop order of each gas turbine 3 and the target number of gas turbines 3 in the operating state after the start operation or after the stop operation. Can be executed appropriately.

  Therefore, in the multi-shaft combined cycle power plant, the start control or stop control of the gas turbine 3 can be simplified.
