Description

  The present invention relates to an electric railway substation monitoring and control system, an electric railway substation monitoring and control apparatus, and an electric railway substation monitoring and control method.

  In general, in substations for railways that are arranged in multiple locations along the track, power receiving circuit breakers and disconnectors are inserted at the same time when feeding is started, and the power is transmitted to the wires. Operation by the substation monitoring and control device for railways is carried out every day so as to release and stop power transmission.

  In addition, the substation monitoring and control system for electric railways prevents the substation equipment from being damaged by the accident current and the trolley wire that supplies power to the vehicle from being blown when an accident occurs in the feeder. There is a protection interlock function. In other words, the substation monitoring and control device for electric railways monitors whether an excessive current is flowing through the equipment, etc., or whether an abnormal voltage is applied, and the equipment is detected from such an excessive current or abnormal voltage. Has a function to protect. Further, the railway substation monitoring and control device is provided with a switching individual interlocking function that automatically switches the power supply system to the vehicle according to a specified time when the vehicle passes near the railway substation.

  In order to ensure the safety of night maintenance work, these functions are subjected to a simulation test in a state where the power receiving circuit breaker cannot be turned on when the power feeding is stopped after the last train.

  In the conventional railway substation monitoring and control system, when performing a simulation test, various settings necessary for the simulation test are made from the setting means provided in the railway substation monitoring and control system, thereby monitoring the railway substation. A simulation test is performed after the control device is set to a simulation setting state (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2006-042494

  Although the mock test performed at the time of stopping the power feeding is performed as a maintenance work, the labor of the test work and the test execution time are being shortened due to the labor saving of the maintenance work in recent years. In addition, the number of test assistants with less expertise is also increasing among test personnel.

  In the simulation setting state, the power feeding before the first train cannot be started normally, so it is necessary to release the simulation setting state surely, but more items are tested in a limited time. It is necessary to return from the simulation setting state in a shorter time and with a smaller number of people.

  However, for example, the simulation setting described in Patent Document 1 can be performed without connecting a cable or the like to the railway substation monitoring and control device. Therefore, there is a possibility that the return from the simulation setting state is leaked.

  The present invention has been made to solve the above-mentioned problems, and prevents return leakage from the simulation setting state even in a substation monitoring and control apparatus for electric railways in which cable connection work or the like is omitted during a simulation test. An object of the present invention is to provide a railway substation monitoring and control system, a railway substation monitoring and control apparatus, and a railway substation monitoring and control method.

  In order to solve the above-described problems and achieve the object, the railway substation monitoring and control system according to the present invention simulates the operation of the equipment installed in the railway substation, and the function test of the railway substation is performed. A substation monitoring and control system for electric railways, comprising a substation monitoring and control apparatus for electric railways capable of performing the operation and a central command station connected to the substation monitoring and control apparatus for electric railways via a network, The railway substation monitoring and control device selects a simulation device that is a simulation target device and outputs a device selection signal, and also sets a setting unit that sets an operation time of the simulation device, and is transmitted from the setting unit When the operation time of the simulation device is set and a control execution signal for instructing execution of the simulation processing is input, the simulation processing of the simulation device is executed and the status signal of the simulation device is output after the operation time of the simulation device. Recognizing the simulated device by the simulation processing means and the device selection signal, when a control command signal for the simulated device is input from the central command station, the control execution signal is output to the simulation processing means, and the simulation processing is performed. Control processing means for outputting the status signal when the status signal is input from the means; and input / output processing means for transmitting the status signal to the central command station when the status signal is input from the control processing means; The central command station determines whether or not the current time belongs to a preset simulation setting time zone, and if the current time does not belong to the simulation setting time zone, a simulation test is performed. A release time determining means for outputting a release command signal for releasing the setting of the device, wherein the setting means outputs the device selection signal when the simulated device is set, and When the selection time of the simulation device is received, the release time determination unit determines whether the time at the time of reception is within the simulation setting possible time zone, and determines As a result, if it is outside the simulation setting possible time zone, the cancellation command signal is transmitted to the setting unit, and the setting unit, upon receiving the cancellation command signal, transmits to the control processing unit and the simulation processing unit Each is characterized by outputting a signal notifying the cancellation of the setting of the mock test.

  According to the present invention, even in a substation monitoring and control apparatus for electric railways in which cable connection work or the like during a simulation test is omitted, it is possible to prevent return leakage from the simulation setting state.

  DESCRIPTION OF EMBODIMENTS Embodiments of an electric railway substation monitoring and control system, an electric railway substation monitoring and control apparatus, and an electric railway substation monitoring and control method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment.
FIG. 1 is a block diagram showing a configuration of a railway substation monitoring and control system according to the present embodiment. In FIG. 1, an electric railway substation 1 and a central command station 6 are shown. The railway substation 1 and the central command station 6 are connected by a network 21.

  The railway substation 1 is provided with a power receiving circuit breaker 2, a disconnecting switch 3, a protection device 4, and an in-substation equipment 5, and these equipment are respectively a railway substation monitoring and control device 7 and a transmission line 22. Connected by. Here, the power receiving circuit breaker 2 receives power from the power system (not shown) to the railway substation 1 or stops receiving power according to the on state or the cut off state.

  The railway substation monitoring and control device 7 includes a setting unit 8, a control processing unit 9, a simulation processing unit 10, and an input / output processing unit 11.

  The setting means 8 enables setting of a simulation test including selection of a simulation device, setting of an operation time of the simulation device, and the like. The simulated device (simulated target device) is, for example, the power receiving circuit breaker 2. When the simulated device is selected, the setting unit 8 outputs a device selection signal to the control processing unit 9 and the simulated processing unit 10, respectively. In addition, the setting unit 8 transmits the operation time of the simulated device to the simulation processing unit 10. The setting means 8 can cancel the simulation test setting. That is, when receiving the cancellation command signal for canceling the simulation test setting from the central command station 6, the setting unit 8 outputs a signal for notifying the control processing unit 9 and the simulation processing unit 10 of the cancellation of the simulation test setting. The setting means 8 and the control processing means 9 are connected by a transmission line 23, and the setting means 8 and the simulation processing means 10 are connected by a transmission line 24.

  The control processing unit 9 recognizes the simulated device based on the device selection signal transmitted from the setting unit 8. Further, when a device control command signal for the simulated device is input from the central command station 6, the control processing unit 9 outputs a control execution signal that instructs the simulation processing unit 10 to execute the simulation process.

  The simulation processing unit 10 sets the operation time of the simulation device transmitted from the setting unit 8 and executes a simulation process when a control execution signal is input from the control processing unit 9. Is output to the control processing means 9. When the status signal is input from the simulation processing means 10, the control processing means 9 outputs this status signal to the input / output processing means 11.

  When the status signal is input, the input / output processing means 11 transmits this status signal to the central command station 6 via the network 21.

  The central command station 6 issues a control command such as outputting a device control command signal. In the present embodiment, the central command station 6 is provided with a release time determination means 13. The cancellation time determination means 13 has data of a preset simulation setting time zone, determines whether the current time belongs to the simulation setting time zone, and determines that it is outside the simulation setting time zone. If so, a cancellation command signal for canceling the simulation test setting is transmitted to the setting means 8. Here, the simulation setting available time zone is a time zone that is set to a time zone after the last train and before the start of feeding and allows a simulation test. The release time determination unit 13 is realized by a PC, for example.

  Next, the operation of the present embodiment will be described. Hereinafter, a simulation process of the power receiving circuit breaker 2 will be described with reference to FIGS. 1 and 2 as an example. FIG. 2 is a flowchart of processing when a function test is performed by simulating the operation of the power receiving breaker 2.

  In FIG. 2, first, in the electric railway substation monitoring and control device 7, the power receiving circuit breaker 2 is selected as a simulation device by the setting means 8 (S <b> 1). Each notifies the start of the simulation process. Specifically, the setting unit 8 outputs a device selection signal to the control processing unit 9 and the simulation processing unit 10, respectively.

  Next, the setting unit 8 notifies the central command station 6 of the selection state (information signal) of the simulated device (S2). That is, the setting means 8 transmits a signal notifying that the power receiving breaker 2 has been selected as a simulation device to the central command station 6. This signal is transmitted to the central command station 6 via the control processing means 9 and the input / output processing means 11.

  On the other hand, when the central command station 6 receives a signal reporting the selection state of the simulation device from the setting means 8, the release time determination means 13 determines whether or not the time at the time of reception is within the simulation settable time zone. (S3). As a result of the determination, if it is outside the simulation setting possible time zone (S3, No), the cancellation time determination means 13 generates a cancellation command signal for canceling the simulation test setting (S14), and this cancellation command signal is set by the setting means. Send to 8. The setting unit 8 that has received the cancellation command signal outputs a signal for notifying the control processing unit 9 and the simulation processing unit 10 of the cancellation of the setting of the simulation test, and ends the simulation test (S15). If the result of determination is that the simulation setting is possible (S3, Yes), the process proceeds to S4.

  Next, in the electric railway substation monitoring and control device 7, the operating time of the power receiving circuit breaker 2 is set in the simulation processing means 10 by the setting means 8 (S4). Then, the central command station 6 outputs a control command signal of a closing command for the power receiving breaker 2 (S5), and this control command signal is input to the control processing means 9 via the input / output processing means 11. The input / output processing means 11 is an interface unit with the power receiving circuit breaker 2, the central command station 6 and the like. For example, “the state of the power receiving circuit breaker 2 has been changed by a command from the central command station 6”. This information is notified to the control processing means 9.

  Subsequently, since the control processing means 9 has received the notification of the simulation process from the setting means 8, it outputs a control execution signal to the simulation processing means 10. When the control execution signal is input to the simulation processing means 10, the simulation processing means 10 outputs a state signal indicating the operation state of the power receiving breaker 2 after the set operation time of the power receiving breaker 2 (S6). .

  Next, when the status signal output from the simulation processing means 10 is input to the control processing means 9, the control processing means 9 transmits this status signal to the central command station 6 via the input / output processing means 11. (S7). That is, the control processing means 9 transmits the simulation result to the central command station 6.

  Further, following the processing of S3, if the setting circuit 8 is set so that the power receiving breaker 2 is not operated (S16), the simulation processing unit 10 is set not to operate in response to the control command from the control processing unit 9. Is done. Alternatively, following the process of S3, the setting means 8 can simulate the operation contacts of the disconnector 3, the protection device 4, and the substation equipment 5 (S17).

  After the process of S7, when the central command station 6 receives a signal reporting the simulation result from the control processing unit 9, the release time determination unit 13 determines whether or not the time at the time of reception is within the simulation settable time zone. Determine (S8). That is, the release time determination unit 13 determines whether or not the simulation setting possible time has elapsed after the simulation processing. As a result of the determination, when the reception time is outside the simulation setting available time zone (S8, No), the cancellation time determination means 13 generates a cancellation command signal for canceling the simulation test setting (S14). A command signal is transmitted to the setting means 8. Then, the setting means 8 that has received the release command signal outputs a signal for notifying the control processing means 9 and the simulation processing means 10 that the setting of the simulation test is canceled, and ends the simulation test (S15). If the result of determination is that the reception time is within the simulated setting time zone (S8, Yes), the release time determination means 13 calculates the “remaining time” until the simulated setting time zone ends. Then, this “remaining time” is notified to the setting means 8 (S9).

  Next, the setting means 8 determines whether there is new input data (S10). That is, the setting means 8 is in a waiting state for performing the next simulation process, and determines the presence or absence of input data for a predetermined time. If there is no input data as a result of the determination (S10, No), the setting means 8 outputs a signal for notifying the control processing means 9 and the simulation processing means 10 of the cancellation of the setting of the simulation test, and ends the simulation test. (S15).

  If there is input data as a result of the determination in S10 (S10, Yes), the setting means 8 determines whether or not the remaining time transmitted from the central command station 6 is equal to or shorter than the first predetermined time (S11). . Here, the first predetermined time is a threshold value indicating that the next simulation process cannot be performed to the end when the remaining time is equal to or shorter than the first predetermined time. That is, when the remaining time is longer than the first predetermined time, at least the next simulation process can be performed to the end. As a result of the determination, when the remaining time is equal to or shorter than the first predetermined time (S11, Yes), the setting unit 8 sends a signal for notifying the control processing unit 9 and the simulation processing unit 10 of the setting cancellation of the simulation test. The simulation test is finished (S15).

  On the other hand, if the remaining time is larger than the first predetermined time as a result of the determination in S11 (S11, No), the setting means 8 further determines whether or not the remaining time is equal to or shorter than the second predetermined time. (S12). Here, the second predetermined time is a threshold value indicating that the remaining time is short although the next simulation process can be performed to the end when the remaining time is equal to or shorter than the second predetermined time. The second predetermined time is longer than the first predetermined time. If the remaining time is equal to or shorter than the second predetermined time as a result of determination in S12 (S12, Yes), the setting means 8 generates an alarm signal and is provided in the railway substation monitoring and control device 7. For example, an alarm for reporting that the remaining time is short is displayed on a display unit (not shown) (S13). When the alarm is displayed, the same content can be reported by voice. After the process of S13, based on the input data, for example, the process after S1 is repeated for another power receiving breaker.

  On the other hand, if the remaining time is larger than the second predetermined time as a result of the determination in S12 (S12, No), the processing after S1 is repeated for another power receiving circuit breaker based on the input data, for example. .

  In the present embodiment, a simulation setting possible time zone is set in advance by the release time determination means 13 of the central command station 6, and the release time determination means 13 starts the simulation process (S3) and ends the simulation process (S8). ), It is determined whether or not the simulation setting time zone has passed. If the simulation setting time zone has passed, the simulation setting state of the railway substation monitoring and control device 7 is forcibly released. ing. Therefore, according to the present embodiment, it is possible to prevent return leakage from the simulation setting state. In particular, in the substation monitoring and control apparatus 7 for electric railways, in which cable connection work or the like is omitted during the simulation test, even if it is difficult to determine whether it is in the simulation setting state from the appearance, the simulation test time at the central command station 6 By monitoring whether or not it belongs to the simulation setting possible time zone, it is possible to prevent a return leakage from the simulation setting state.

  In the present embodiment, the simulation setting cancellation time is determined at the central command station 6 and the cancellation command signal is output when the simulation setting available time period has elapsed. It is possible to collectively manage the return leakage prevention from the simulation setting state at the station 6 and to easily match with other control command signals issued from the central command station 6.

  In the present embodiment, after the simulation process is completed, if there is more input data, the setting means 8 determines whether or not the remaining time is equal to or shorter than the first predetermined time. As a result, it is possible to avoid a situation in which time runs out during the next simulation process. Furthermore, in the present embodiment, the setting means 8 determines whether or not the remaining time is equal to or shorter than the second predetermined time, and displays an alarm when the remaining time is equal to or shorter than the second predetermined time. The person can recognize in advance that there is little remaining time.

  The process shown in FIG. 2 is an example, and various modifications can be made. For example, it is possible to omit the determination process in S8 while performing the determination process in S3. In addition, for example, a mode in which processing such as S12 and S13 is omitted and alarm display is not performed is also possible.

  In this embodiment, the release time setting means 13 is provided in the central command station 6. However, the release time setting means 13 may be provided in the electric railway substation 1, for example, in the electric railway substation monitoring and control apparatus 7. . In this case, since there is no need to go through the network 21, the system can be simplified and the network 21 is not affected by troubles (such as communication failure).
