Description

  Embodiments described herein relate generally to a protective relay device that can reduce the burden on maintenance operators and improve work efficiency.

  The digital protection relay device converts the electric quantity and state quantity of the power system into a digital quantity, performs a predetermined protection control calculation using the converted digital quantity, and issues a circuit breaker switching command according to the calculation result. The power system is protected by outputting.

  In addition, in the digital protective relay device, generally, a set value that is a reference for operation and operation is stored in a storage memory, and the set value and operation setting stored in the storage memory from a distance via a network are stored. Change operation is possible.

  For example, when a transmission line composed of two terminals, two lines, and two lines is protected by a plurality of protective relay devices, it is conceivable that some of the protective relay devices are operated with the same set value. In such a case, conventionally, target devices are selected one by one from a plurality of protective relay devices, and the elements of the set value are changed one by one. However, this method is inefficient, is burdensome in terms of operation, and may cause human error.

Further, a set value operation interface (for example, a personal computer interface) 5 is connected to the transmission network 4 so that data can be transmitted to and received from the digital protection relay devices 2-1 to 2-20.

  Here, the digital protection relay devices 2-2 to 2-9 within the range indicated by the group I are digital protection relay devices that require operation with the same set value.

(Configuration of digital protection relay device)
FIG. 2 is a block diagram illustrating a configuration of the digital protection relay device according to the first embodiment. This digital protection relay device 2A has an interface connection unit 11 for connection to the personal computer interface 5, a group data recognition unit 12 for receiving and recognizing group data set by the personal computer interface 5, and an input by the personal computer interface 5. A set value data receiving unit 13 that receives the set value data, a set value data storage unit 14 that stores the received set value data, and a set value data transfer that transfers the received set value data to another protective relay device. Part 15.

  The digital protection relay devices 2-1 to 2-20 shown in FIG. 1 all have the same configuration, and among these, the device that is first connected to the personal computer interface 5 via the transmission network 4 is the same. The digital protective relay device 2A is used.

(Configuration of PC interface)
FIG. 3 is a block diagram illustrating a configuration of the personal computer interface according to the first embodiment. The personal computer interface 5A includes a protection relay device connection unit 21 for connecting to the digital protection relay device 2A, a group data creation unit 22 for creating group data relating to the protection relay device, and digitally protecting the created group data. A group data transmitter 23 for transmitting to relay device 2A, a set value data generator 24 for generating set value data, and a set value data transmitter for transmitting the generated set value data to digital protection relay device 2A 25.

(How to change settling values at once)
A set value batch change method using the digital protective relay device 2A having the above-described configuration and the personal computer interface 5A will be described with reference to the flowchart of FIG.

  First, a maintenance operator connects the personal computer interface 5A to the transmission network 4 and determines one protective relay device to be connected. Thereby, the protection relay device connection unit 21 of the personal computer interface 5A connects to the interface connection unit 11 of the determined protection relay device 2A (hereinafter referred to as a representative device) via the transmission network 4 (S11).

  Next, the group data creation unit 22 of the personal computer interface 5A recognizes and displays all the protection relay devices 2-1 to 2-20 connected on the transmission network 4. The maintenance operation worker includes the representative relay device among all the displayed protective relay devices 2-1 to 2-20 and operates with the same set value (for example, 2-2 to 2-9) is selected (S12). At this time, the maintenance operator can select the protective relay device according to the guidance on the PCHI (personal computer human interface) such as the line name and the substation. Alternatively, a plurality of devices can be selected by designating the IP address of the target protective relay device.

  Next, the group data creation unit 22 groups the plurality of selected protection relay devices, and whether all the devices in the group are in a state where settling operation is possible (that is, the selected protection relay device has an abnormality). Whether there is no problem if the settling value is changed (S13). If there is no problem, the group data creation unit 22 creates group data for the protective relay device whose setting values are to be changed collectively (S14).

  Next, the group data transmission unit 23 transmits this group data to the representative digital protection relay device 2A connected by the interface connection unit 11 (S15). The group data recognition unit 12 of the representative digital protection relay device 2A receives the group data, and thereby recognizes that the own device belongs to the group whose settling value should be changed.

  Next, when the set value data is set from the personal computer interface 5A (S16), the set value data creation unit 24 performs a check to confirm that there is no problem with the set value (S17). If there is no problem (YES in S17), this is set as the set value data, and the set value data transmission unit 25 transmits this data to the representative digital protection relay device 2A connected by the interface connection unit 11 (S18). .

  On the other hand, if there is a problem with the set value (NO in S17), settling value data is set again (S16).

  In the representative digital protection relay device 2A, when the set value data receiving unit 13 receives the set value data, the set value data storage unit 14 stores the set value data as the operation value of the own device (S19). Further, the set value data transfer unit 15 transfers the set value data to another protection relay device recognized as the same group by the group recognition unit 12 (S20).

  In other digital protection relay devices, the set value data receiving unit 13 receives the set value data, the set value data storage unit 14 stores the set value data as the operation value of the own device, and the set value data transfer unit 15. The settling value data is transferred to another protection relay device recognized as the same group. In this way, the data is sequentially transferred to other protection relay devices belonging to the same group, and the reception, storage, and transfer of the set value data are repeated until there is no transfer target.

  During the setting value changing operation, the protection function of the target device is temporarily locked, and the lock is released after the setting value has been reliably changed.

  In addition, each digital protection relay device temporarily saves the set value data when receiving the set value data, and at the time specified by the data received together with the set value data or at the time specified in advance as the operating value all at once. By saving, the digital protection relay device in the group can be tuned to change the operation value. By changing the operation value in synchronism in this way, the time required for the change operation is shortened. Therefore, even when the operation of the target system is suspended during the setting value changing operation, the suspension time can be shortened, and the power system can be stably operated.

(effect)
In this embodiment, the set value is changed by transferring the set value data to all the devices that are the targets of the set value change selected as the same group from the protective relay devices installed in the power system. Can be performed in a lump.

  For this reason, when changing the set value of the protective relay device, the maintenance operator does not need to change the set value for each change target device, and can quickly change the set value of the target device. It becomes possible.

  Therefore, according to this embodiment, while reducing the burden of a maintenance driving | operation worker, the risk of a human error can be reduced and work efficiency can be improved.

[Other embodiments]
(1) In the above embodiment, an example in which the set value is collectively changed for the digital protection relay device in the group I installed on the transmission line composed of the two-terminal two-line two-line system shown in FIG. It can also be applied to a plurality of transmission lines. For example, as shown in FIG. 14, among the digital protection relay devices 2-21 to 2-28 installed in the four-line transmission line, the digital protection relay devices 2-21 to 2-24 in the group III and the group Since the same set value is required for the digital protective relay devices 2-25 to 2-28 in the IV, it can be applied to the devices in these groups. In addition, it is possible to apply and apply a digital protective relay device installed on a transmission line of a duplexed or two-line system with the same set value.

(2) In each of the above embodiments, the set value data is transmitted to the representative digital protection relay devices 2A to 2C and then transferred to other digital protection relay devices in the same group one by one through the representative device. However, based on the group data created by the group data creation unit 22, the set value data is simultaneously transmitted from the representative digital protection relay devices 2A to 2C to all the other digital protection relay devices in the group. It can also be sent.

(3) In the above embodiment, the set value data transmitted from the personal computer interfaces 5A to 5D to the digital protection relay devices 2A to 2C is data relating to all the setting items stored in the digital protection relay devices 2A to 2C. Alternatively, it may be data relating to a part of the settling items.

(4) The set value data storage unit 14 in the digital protection relay devices 2A to 2C is configured by a shared unit and a specific unit, and a target for which set value data is changed by batch setting of a plurality of devices is set as the shared unit. It can also be memorized.

  For example, as shown in FIG. 15, when the digital protection relay devices 2-31 to 2-36 are applied to a three-terminal system, all of the current differential relays have the same set value, but the protection range of the distance relay Is the protection range α of the distance relay at the A end> the protection range β of the distance relay at the B end> the protection range γ of the distance relay at the C end, and the protection range varies depending on the terminal. For this reason, the distance relay is set to an individual set value. Therefore, it is preferable that the set value by the current differential relay is used as a shared part of the memory and the set value by the distance relay is stored in a specific part of the memory.

  In this way, by dividing the memory of the set value data storage unit 14 into the shared unit and the unique unit and storing them, even if the data is corrupted when transferring the set value data to a plurality of devices, The settling value elements that are stored are not affected. The settling value data of the specific part can be changed by directly accessing the IP address of the protective relay device. In this case, the operation in which the digital protective relay device receives the set value data by the set value data receiving unit 13 and stores the set value data by the set value data storage unit 14 is the same as the procedure described in each embodiment.

(5) Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
