  According to the supervisory control system of the present invention, data such as state change acquired in the supervisory control device provided in the power generation / substation etc. is transmitted to the system such as the control station in an integrated format, and alarm / display / record etc. Since the message output is performed by an integrated message processing system, the volume of data transmitted from the supervisory control device can be greatly reduced.

  In addition, since the monitor control device does not create message output data, it is possible to reduce the burden on the person in charge of each monitor control device caused by changing the message content.

  Further, since the data to be output as a message is created centrally in a system such as a control station, the format of the data differs depending on the person in charge of the supervisory control device, which may hinder the understanding of the output message. The situation can be avoided.

  Further, in the monitoring control system of the present invention, a business execution right is set for an operating entity having the authority to control the target device, and a message such as a status change is also output based on information on the business execution right of the operating entity. Therefore, a message can be reliably transmitted to the operation control point.

  Furthermore, since the business execution right is changed according to the change of the driving form authority, the information of the operating subject that is the target of the message output is also automatically changed.

  The “business type table” shown in FIG. 7 manages business execution type data such as execution rights and control rights.

  The message record DB 132 of the storage unit 13 stores the history of output messages (FIG. 8).

  Next, regarding the operation in the monitoring control system 1 having the above-described configuration, a process in which the monitoring control device (information collection and distribution device) 2 acquires the state change data of the equipment and transmits it to the control station system 10A, and the control station system 10A After receiving the state change data, the process will be described separately for the process of alarming, displaying, recording and the like.

[State change data transmission processing]
First, in a monitoring control device (information collection and distribution device) 2 provided in a power generation / substation, etc., when a state change or the like occurs in a device subject to monitoring control, data for notifying the state change or the like is acquired, and the control station system Processing up to transmission to 10A will be described with reference to FIG.

In the monitoring control device (information collection and distribution device) 2 provided in the power generation / substation, etc., monitoring control of devices such as the power transmission line CB6 under its jurisdiction is performed, and when a state change or line abnormality occurs in the monitoring control target device, It receives SV data including information such as state changes, TM data, waveform data, image data, audio data, various recording data, and the like. The received data is processed and calculated on site, processed into data in an integrated format, and transmitted to the control center system 10A (data transmission means 223).
Here, the integrated format means a format (hereinafter referred to as “telecon format”) corresponding to a channel through which the monitoring and control apparatus transmits data.

  In addition, the transmitted SV data includes data on the time when occurrence of a state change or the like is detected by the time stamp function provided in the monitoring control device (information collection and distribution device) 2. By including the initial time data in the SV data, there is an effect that it does not take time to grasp the accident situation even if there is a delay in the transmission path.

[Status change alarm display recording process]
Next, in the control center system 10A constituting the supervisory control system 1, an outline of processing from receiving data transmitted from the supervisory control apparatus (information collection / distribution apparatus) 2 until outputting a message is shown in FIG. .

  The control center system 10A that has received the data analyzes the information such as the state change by the telecon format by the message type extracting unit 123, and creates a message such as an alarm, display, and recording by the message creating unit 124.

In the flowchart of FIG. 10, the flow of data for extracting the message type from the received data will be described (message type extracting means 123).
First, the message type extraction unit 123 is activated upon reception of data indicating that a power change has occurred in the power transmission line CB6 (S101). The data includes “data address” indicating the unique name of the transmission line CB6 in which the state change has occurred and “type number” indicating the status change type “transmission line CB = ON → OFF”.

  The message type extraction unit 123 acquires the “type number” included in the status change type data (S102), and refers to the “type table” included in the message processing system DB 131 (S103).

  Here, the “type number” is assigned for each type of status change in the target device for monitoring control, and is managed in the “type table” of the message processing system DB 131 shown in FIG. The “type name” in the “type table” is described as a general name of the model.

  In general, many transmission lines CB are installed in the supervisory control system, but there is only one data for each model referred to in the extraction of the message type. That is, even if a state change occurs in any power transmission line CB, the output result of the message type to be output is not affected.

  The message type extracting unit 123 sequentially acquires individual “message numbers” from the “message numbers” displayed in the “individual monitor” and “combination monitor” fields of the “type table” (S104). The message creation means 124 described later is activated to pass data. Note that a collection of “message numbers” is set in advance according to the “type number”.

  In the “alarm display setting table” of the message processing system DB 131 shown in FIG. 5, the behavior (output form) of the format, color, display location, output destination, alarm, voice, etc. of the message output corresponding to “message number” and the like ) Is finely set.

  Although details will be described later, the message creation unit 124 refers to the “alarm display setting table” based on the “message number” set as “111, 111, 151,...” In the “type table” (FIG. 4) ( S105). Next, the message creation unit 124 extracts “message format” and “message output pattern” (S106 and S107).

  In this example, the “message format” indicating the item of data to be extracted is an item such as an electric station name, a device name, and an operation name, and the message creation unit 124 extracts the corresponding data from the unique table (FIG. 3). (FIG. 5).

Next, “business execution rights” will be explained.
The “execution authority” is an authority given to an operating subject who can perform a control operation on the device. In this embodiment, the “execution authority” is managed by the “execution authority table” included in the message processing system DB 131. . If the operation form authority is changed, it is necessary to change the setting of the business execution right in the “business execution right table” (the business execution right setting means 125), so that the current operation control point is surely grasped. be able to.

  In the “business execution right table” in this embodiment, the “command right” for instructing or permitting the control, the “control right” for actually executing the control, and the contents such as the state change are transmitted and transmitted. The right to receive “contact transmission right”, “record management right” and the like are separately managed (FIGS. 6 and 7). As a result, only an authorized person can monitor and control devices and perform other necessary tasks, thereby enabling highly reliable system monitoring and control.

In this embodiment, in the “business execution right table” shown in FIG. 6, management of an operation subject that can be controlled for each device is performed. The business execution right setting unit 125 sets the business execution right of the appropriate operating entity in the data of the corresponding device in accordance with a command from the operating body in which the “command right” is set.
As a result, for example, it is possible to manage information such as the current operation by the distribution automation system 10B or the direct operation by the control center system 10A.

  The business execution right reference means 126 receives the message type extracted by the message type extraction means 123 and executes it, and refers to the “business execution right table” to indicate data indicating the business execution right for a device in which a state change or the like has occurred. The information of the operation subject having is acquired.

  Based on the business execution right data acquired by the business execution right reference means 126, the message type extraction means 123 specifies a department in charge or other system that needs a buzzer or voice alarm, contact or transmission, and the like.

  These specifications are defined by “message number” held in the “type table” of the message processing system DB 131. In other words, what kind of behavior the operation subject set with “control right” performs, what kind of behavior the operation subject set with “contact transmission right”, etc., combinations of numbers in “message number” etc. Is set more specifically.

  Note that a separate table indicating the association between the individual message numbers in the type table and the level of business execution rights may be maintained separately so that the same message behaves according to the level of business execution rights. .

  As described above, the content created as a message includes data of the operation subject that can control the device specified by the “business execution right table” and data of “message number” specified by the “type table”. Then, based on the alarm display setting in the “alarm display setting table” and the data of the message format (target electric station name, device name, operation name, etc.), the alarm / sound, its route display, etc. are determined.

  These are message specific information such as “Voltage Class”, “Affiliation Area”, “Affiliation Power System”, etc., which are unique data of the transmission line CB6, and the message display and message recording are classified (by voltage, system, content). According to other, electric station, etc.).

In the flowchart of FIG. 11, the flow of data when a message is output will be described (message creation means 124).
The message creating unit 124 in this embodiment is activated upon receiving the message extracted by the message type extracting unit 123, and is based on the “message output pattern” defined corresponding to the “message number” in the “type table”. An actual message is created (FIG. 5).

  First, the message creation unit 124 extracts the data of “data address” transmitted from the monitoring control device (information collection and distribution device) 2 (S201), and the message processing system DB 131 is provided based on the unique “data address”. Data of the target device is referred to from the “unique table” (S202).

  Next, the message creation unit 124 extracts individual data from the referred “unique table” (S203). In the example shown in FIG. 3, target device data such as “electricity station name”, “device name”, and “operation name” is extracted and held as actual data of “message format” (FIG. 5).

  Based on the “message number” and the actual data of “message format” passed from the message type extraction unit 123, the message creation unit 124 creates a “message output pattern” from the “alarm display setting table” provided in the message processing system DB 131. Data is extracted (S204).

  Next, the message creation unit 124 formats the display location (0...) Corresponding to the extracted “message output pattern” “0... 0, 0, YB˜” (FIG. 3). (0 ..), color (YB), etc., are actually output (S205). The message output pattern here is an example, and may be a temporal element such as a storage location or a display order.

  Next, in this example, on the basis of the business execution right data extracted by the business execution right reference means 126, real-time message display, aggregate display, ringing by alarm / sound for the operation subject to which the business execution right is set Communication / transmission, message recording, etc. are performed (S206).

  The output message record is stored in a message record table or the like of the message record DB 132 according to classification by voltage, system, content, electrical location, or the like (FIG. 8).

  As described above, according to the monitoring control system 1 of the present embodiment, the capacity of data transmitted from the monitoring control device 2 is greatly reduced, and the burden on the person in charge of each monitoring control device caused by a change in message content or the like Can be reduced.

  In addition, since the data to be output as messages is created centrally, it is easy for the person in charge to understand the messages, and the work safety can be ensured.

  Furthermore, since the operation control location can be surely grasped by the business execution right, an erroneous message output can be avoided.

  In addition, in the monitoring and control system according to the present invention, when the occurrence of a state change or the like is detected, a time stamp is made by the local monitoring and control apparatus, so that the state change may be mixed up or down due to a transmission path delay or the like. In addition, it is possible to easily grasp the accident situation.

  The monitoring control system of the present invention is not limited to the above embodiment, and various effects can be achieved by changing the setting.

  For example, the monitoring control device 2 having the information collection and distribution function includes the message type extracting unit 123, the message creating unit 124, the business execution right setting unit 125, the business execution right reference unit 126, and the like, and the control center system 10A for the created message The transmission to the distribution automation system 10B / feeding station system 10C can be set to use an area corresponding to the channel on which the monitoring control device (information collection and distribution device) 2 performs transmission.

  As a result, message creation and management can be unified, so that business execution rights can be managed more efficiently.
