Description

IEC-61850 based substation automation system device and control method {Apparatus for Substation Automation System Based On IEC-61850 and Method

The present invention relates to an automation system of a substation. In particular, the IEC-61850 device (device) newly installed in the existing substation and DB construction and by creating an image for the searched device to display the configuration screen, the automation system of the substation The present invention relates to an IEC-61850 based substation automation system and its control method which can be easily constructed.

Communication protocols used for automation in existing substations include DNP 3.0 (Distributed Network Protocol) and MODBUS. The communication protocols are all fieldbus communication methods.

Figure 1 shows a substation automation system employing the fieldbus communication method DNP3.0 or Modbus.

Referring to FIG. 1, a plurality of intelligent electronic devices (IEDs) 10 based on a field bus are provided. It measures the power status and quality of the water / distribution panel and judges the system breakdown, and operates the breaker according to the result to provide the power supply and interruption function. In other words, it is installed in substations such as disconnectors, breakers and transformers. It collects the operation state information on the field equipment through the sensor (CT, PT) 12 and serves to transmit to the same controller.

Remote terminal unit (RTU) for collecting the operation status information and accident information of the field equipment through the fieldbus, and remotely controlling the field equipment so that the accident site can be promptly processed based on the collected information. 20 is provided. For reference, in the system based on the IEC-61850 communication based on the IT technology of power automation, the remote terminal unit also serves as one IED device.

The IED 10 and the remote terminal unit 20 and the field equipment are connected and connected in a hard-wiring manner.

An HMI unit (Human Machine Interface) 30 is provided for receiving data from the remote terminal unit 20 or controlling the field equipment through a remote control command. The HMI 30 displays the data converted by the RTU 20 on a computer screen or a display device so that an administrator or an operator can visually confirm. The HMI 30 may be configured in an embedded form on one board provided in the remote terminal unit 20.

However, the existing substation configuration was hard-wiring, so the working environment in the substation was not good, and complex cable work was necessary even if additional facilities were added.

In addition, if the system is to be added or changed, it is not easy to build a database or to interoperate with an upper display device.

These problems are due to the use of fieldbus communication method DNP3.0 or Modbus as described above.

Therefore, recently, the IEC-61850 protocol, which is an international standard for automation of substations, has been proposed, and the IEC-61850 protocol is expected to be widely used in the future.

The reason is that, while the substation system to which the IEC-61850 protocol is applied is designed, the existing local control panel (LCP) can be digitized to remove the cable connected to the existing hard-wiring, and to use optical communication. This is because it is possible to manage all the information easily. In addition, the expansion period can be shortened even when the system is expanded or changed, and at the same time, it provides an environment that can easily solve the interface problem with the existing system. Therefore, the new substation is being built as an automation system based on IEC-61850.

However, IEC-61850-based substation automation systems that are currently being built and used are practically not fully operational on the basis of IEC-61850.

Therefore, the current substation is interfaced through a gateway or a protocol converter in order to use the IEC-61850-based protocol.

Therefore, even the substation automation system based on IEC-61850 still has the problems of the existing substation automation system.

In other words, IEC-61850-based devices are installed in the substation automation system in the future, but in the current system, there is no way to automatically check the devices even if IEC-61850-based devices are installed.

In addition, since the installation of the IEC-61850 device is not immediately available, there has been a hassle of an administrator or an operator to separately perform setting for using the device.

In addition, even when the IEC-61850 device is installed, it is difficult to build a database based on this information, which makes it difficult to configure the screen of the substation automation system.

As a result, even though the substation using the IEC-61850-based protocol to build the automation system, there are still problems in the database construction and interworking problems.

Accordingly, an object of the present invention is to solve the above problems, and to monitor a substation network to search for a new IEC-61850 device and automatically build a database.

Another object of the present invention is to facilitate the interworking of the IEC-61850 device with the host system.

According to a feature of the present invention for achieving the above object, a smart I / O device for monitoring a substation network to search for a new IEC-61850 device; A tag information construction unit installed in the smart I / O device and configured to build a DB while reading and tagging the information of the retrieved IEC-61850 device, and transmitting the tagged information; A storage unit for storing the tagged information; And when the tagged information is transmitted, a display device for generating an image corresponding to the IEC-61850 device and displaying a substation configuration screen according to an editing function.

A tag information provider for providing tag information corresponding to the smart I / O device for tagging the IEC-61850 device; And an image information providing unit for providing an image for each of the IEC-61850 devices such that the display apparatus generates the image.

A mode selection unit is further included to select and display an image displayed on the substation configuration screen by an automatic method or a manual method. The automatic method displays the image on a corresponding position of the substation configuration screen when the image is generated. Is indicated by Drag & Drop.

According to another feature of the invention, the smart I / O device for monitoring the network of the substation for searching whether the IEC-61850 device is connected to the substation; When the IEC-61850 device is found as a result of the search, the smart I / O device reading and tagging the information of the IEC-61850 device; Transmitting, by the smart I / O device, the tagged information to a display device; And generating, by the display apparatus, an image corresponding to the tagged information and displaying the image on the configuration screen of the substation.

When the image of the retrieved IEC-61850 device is displayed on the configuration screen, the IEC-61850 device starts collecting information on various facilities installed in the substation, and sends the collected information to the smart I / O device in IEC-61850. 61850 communication method.

The image display on the configuration screen is automatically displayed on the configuration screen when the image is generated, or is displayed by a drag and drop method when the image is generated.

According to the IEC-61850-based substation automation system and the control method of the present invention has the following effects.

First, when an IEC-61850 device is installed in an existing substation, the smart I / O device automatically searches for a DB to build a DB, transmits tag information to a display device, a higher system, and the display device generates an image accordingly. It is displayed on the configuration screen and the function is executed.

As a result, even if the IEC-61850 device is newly installed in the existing substation, it is easy to interwork with the upper system, so that the automation system of the substation can be easily constructed.

This allows for efficient management of substation systems and reduces maintenance and labor costs.

Hereinafter, a preferred embodiment of an IEC-61850 based substation automation system device and a control method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of an IEC-61850 based substation automation system device according to an embodiment of the present invention.

Referring to FIG. 2, an IEC-61850 device 100 is provided which collects operation state information and alarm information of various substation facilities and provides them to a smart I / O device 110 described later. The IEC-61850 device 100 and the smart I / O device 110 are connected to each other by an IEC-61850 based communication method.

Smart I / O device 110 is provided that monitors the entire network of the substation.

The smart I / O device 110 has a function of determining whether a new IEC-61850 device is searched in a substation and, when an IEC-61850 device is searched, reads information of the device and displays tag information. (Database) Performs the function of building. To this end, the smart I / O device 110 is connected with a tag information providing unit 114 and a database 116 that provide corresponding tag information for tagging the retrieved IEC-61850 device. In addition, the smart I / O device 110 includes a tag information configuration unit 118 for building the tag information. The tag information configuring unit 118 may be installed outside the smart I / 0 device 110.

The smart I / O device 110 also communicates with an IEC-61850 device that is already installed, and collects operation state information and alarm information of various field devices and provides the higher level display device to be described later.

The smart I / O device 110 is connected to the remote host 120. The remote host 120 performs a function of notifying whether a new device has been found according to a request of the smart I / O device 110.

The smart I / O device 110 receives the tag information and generates an image such as a figure or a symbol corresponding to the tag information so that an administrator can easily recognize the tag information. A display device 130 for displaying the information on each component or the like.

An image information providing unit 132 is provided to provide the image so that the display device 130 may generate an image such as a picture and a symbol for each tag.

The display device 130 displays the image on the configuration screen in two ways. That is, the generated image is automatically displayed at a predetermined position of the configuration screen, or is displayed by a manager using a drag & drop function. To this end, a mode selection unit 140 for selecting the image display method and a HMI unit 150 for automatically displaying the image at a predetermined position of the configuration screen are provided. In general, when the mode selection unit 140 is selected, the mode selection unit 140 is automatically displayed by the HMI unit 150, and when not selected, the mode selection unit 140 is configured to be displayed by the drag and drop function. Of course, in the opposite case, that is, the drag and drop function can be used when the mode selector 140 is selected.

Figure 3 is a flow chart for controlling the IEC-61850 based substation automation system apparatus according to an embodiment of the present invention.

First, in the state where the IEC-61850 device 100 is installed in the substation system, the IEC-61850 device 100 is configured with information of substation facilities from various sensors installed in the substation, for example, operation state information and alarm information of field equipment. Collect the back (s100).

Information collected by the IEC-61850 device 100 is to be transferred to the smart I / O device 110 (s102).

Then, the smart I / O device 110 transmits the information to the display device 130, and also stores the information in the DB 116 because the information is necessary for the operation of the substation. At this time, tag information about the IEC-61850 device is not generated. In other words, the already installed IEC-61850 device stores information in the DB 116 and is displayed as an image corresponding to the configuration screen.

The display device 130 receiving the information displays or outputs the screen so that an administrator can easily recognize the information, and the smart I / O device 110 measures and measures the substation system through the IEC-61850 device 100. Perform the control function (s104).

Meanwhile, the smart I / O device 110 continuously monitors whether the device is newly connected to the substation network while continuously communicating with the remote host 120 (s106). In the communication method, the smart I / 0 device 110 receives a response by transmitting an IP datagram to the remote host 120. Of course, the smart I / O device 110 continues to transmit the information collected from the IEC-61850 device 100 to the display device 130 while the monitoring operation is performed.

Monitoring operation for the device, the smart I / O device 110 is to distinguish between the general device and the IEC-61850-based device of the newly connected device (s108). That is, when the smart I / O device 110 transmits a request signal for whether a device is connected to the remote host 120, the smart I / O device 110 responds to the smart I / O device 110 from the remote host 120. This is because the signal format is different for general devices and IEC-61850 devices. In the present embodiment, when the general device is found, only an action that an administrator can confirm is performed (s110).

Once the device is newly discovered, and the device is determined to be an IEC-61850 based device, the smart I / O device 110 automatically reads the information of the IEC-61850 device 100. (S112). This is possible because it uses IEC-61850 based communication. For reference, in FIG. 2, the reference numeral '100' refers to an already installed IEC-61850 device, but a newly searched IEC-61850 device is also denoted by reference numeral '100'.

As such, when the IEC-61850 device 100 is searched, the smart I / O device 110 brings the relevant tag from the tag information providing unit 114, and the tag information configuring unit 118 reads the tag. Each information is tagged (hereinafter, referred to as 'tag information') by being classified into groups (that is, control, measurement, etc.) used in the display device 130. The tag information is stored in the DB 116 by the smart I / O device 110 (s114).

In addition, the smart I / O device 110 transmits the tag information to the display device 130 (s116).

The display apparatus 130 reads image information corresponding to a tag from the image information providing unit 132 based on the tag information and generates an image corresponding to each tag information (S118).

The generated image is displayed at a predetermined position of the configuration screen provided by the display device 130 to configure the configuration screen (S120).

There are two ways to display an image on the configuration screen.

First, the mode selector 140 is selected.

In this case, the HMI unit 150 automatically displays the image at a corresponding position of the configuration screen. This is because the IEC-61850 device 100 searched by the smart I / O device 110 is classified according to its function or structure, and thus the tags and images corresponding to the tags are different. This is possible because the position where the -61850 device 100 is displayed is determined to some extent.

Second, the mode selector 140 is not selected.

In this case, the administrator or operator moves the image using the drag and drop function and displays it on the configuration screen.

Of course, the mode selection unit 140 may be selected so that the HMI unit 150 may not automatically display an image corresponding to the IEC-61850 device 100 on the configuration screen. That is, when a plurality of IEC-61850 devices 100 that perform the same function are searched or the position to be automatically displayed on the configuration screen is not clear, the HMI unit 150 configures the display device 130. The image is displayed on a predetermined portion of the screen, and the administrator is notified that the image can be directly displayed because the current image is not displayed at the proper position of the configuration screen.

Once the image of the retrieved IEC-61850 device 100 is displayed on the configuration screen, this means that the configuration screen is completed. This is a point in time when the IEC-61850 device 100 starts to collect information on various facilities installed in the substation, and transmits the collected information to the smart I / O device 110 by the IEC-61850 communication method. It is present.

Therefore, in step 104, the smart I / O device performs the measurement and control function using the IEC-61850 device 100.

Meanwhile, the display device 130 may not display only the configuration screen but also display related information collected by the IEC-61850 device 100.

As described above, in the present invention, when various devices based on IEC-61850 are newly installed in the existing substation system, the DB construction and tag information are generated by searching for them, and the image is generated through the tag information to construct the substation. You can see that the screen can be configured.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.
