Technical Field

Background

The measurement and control device of the transformer substation is an acquisition and control unit serving an automation system of the transformer substation. When the entity interval measurement and control device fails or overhauls and exits to operate, the standby measurement and control device is put into operation, so that the reliability of the measurement and control function of the current interval is improved. Based on cost consideration, the standby measurement and control is designed to be deployed in a centralized way, namely one redundant measurement and control device integrates a plurality of interval measurement and control functions and is used as a standby device for measuring and controlling a plurality of interval entities at the same time, and the centralized standby measurement and control is also called cluster measurement and control. The single cluster measurement and control device needs to be capable of carrying out functional backup on at least 15 intervals in the transformer substation, so that at least 15 virtual intervals need to be controlled in cluster measurement and control, and the functions and the configuration of each virtual interval are the same as those of an entity interval.

The conventional virtual interval input method is to fixedly operate 15 virtual intervals on a cluster measurement and control device. However, the method requires that the cluster measurement and control device can load the virtual measurement and control functions of 15 entity intervals at the same time, so that a multi-core or multiple process layer plug-in units are required to realize the operation of multiple virtual intervals, which results in excessive operation cost.

In practical application, the measurement and control device of the transformer substation is an acquisition and control unit serving an automation system of the transformer substation. When the entity interval measurement and control device fails or overhauls and exits to operate, the standby measurement and control device is put into operation, so that the reliability of the measurement and control function of the current interval is improved. Based on cost consideration, the standby measurement and control is designed to be deployed in a centralized way, namely one redundant measurement and control device integrates a plurality of interval measurement and control functions and is used as a standby device for measuring and controlling a plurality of interval entities at the same time, and the centralized standby measurement and control is also called cluster measurement and control. The single cluster measurement and control device needs to be capable of carrying out functional backup on at least 15 intervals in the transformer substation, so that at least 15 virtual intervals need to be controlled in cluster measurement and control, and the functions and the configuration of each virtual interval are the same as those of an entity interval.

Referring to fig. 1, fig. 1 is a schematic structural diagram of cluster measurement and control according to an embodiment of the present application. As shown in fig. 1, the cluster measurement and control 10 includes: the power plug-in 101, the in plug-in 102, the process layer plug-in 103 (, the management plug-in 104, the display plug-in 105, the bus 106 and N virtual spaces 107 (only three are shown in the figure), the in plug-in 102, the process layer plug-in 103, the management plug-in 104, the display plug-in 105 and the virtual spaces 107 are all connected with the power plug-in 101, and the management plug-in 104 is respectively connected with the display plug-in 105 and the virtual spaces 107, wherein N is greater than 1.

In the embodiment of the present application, the power plug-in 101 is configured to provide power for the entire cluster measurement and control 10.

The add-in 102 is used to collect hard add-in signals.

The process layer plug-in 103 is used for accessing a process layer Sampling Value (SV) message, receiving and transmitting a substation event (Generic Object Oriented Substation Event, GOOSE) message facing a general object, and calculating and processing to realize functions of remote signaling, telemetry, remote control and the like of the measurement and control device.

In one embodiment of the present application, to reduce the number of plugins and reduce hardware cost, the process layer plugin 103 may include a first process layer plugin 1031 and a second process layer plugin 1032, where the first process layer plugin 1031 and the second process layer plugin 1032 are four core chips, and each four core chip includes a first chip core, a second chip core, a third chip core, and a fourth chip core. The first chip core is used for completing data processing operation of message information, namely, is used for accessing a process layer SV message and receiving and transmitting a GOOSE message, and each of the second chip core, the third chip core and the fourth chip core can process collection core calculation of telemetry data of a set number of different virtual intervals 107, so that the second chip core, the third chip core and the fourth chip core can complete data processing operation of all the virtual intervals of the transformer substation.

It should be noted that, because the first process layer plug-in 1031 and the second process layer plug-in 1032 operate all the time after the cluster measurement and control 10 is powered on, they are not affected by the input and the output of any one virtual interval 107, so when any one virtual interval 107 exits, the cluster measurement and control can still check the remote signaling and telemetry data of any one virtual interval 107 in real time; meanwhile, the remote signaling and telemetry data of any one virtual interval 107 can be used for comparing the data of the same point location of the corresponding entity interval measurement and control, so that when the measurement and control data of the entity interval is in doubt, the remote signaling and telemetry data of the corresponding virtual interval can be referred.

In this embodiment, the management plug-in 104 is a multi-core chip, and is configured to control the use of any virtual interval 107 and the use of any virtual interval 107, and perform station-controlled layer communication of N virtual intervals 107.

The display insert 105 includes liquid crystals and keys to provide a UI interface display.

It should be noted that, the process layer plug-in 103 and the management plug-in 104 communicate through the bus 106 to implement the uploading of the telemetry data of the remote signaling and the issuing of the remote control command.

Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation method of virtual interval throw-in according to an embodiment of the present application. In this embodiment of the present application, the execution main body of the virtual interval input method is cluster measurement and control, and may also be a management plug-in cluster measurement and control.

As shown in fig. 2, the method for inputting the virtual interval according to an embodiment of the present application may include S101 to S103, which are described in detail below:

in S101, when the first entity bay in the substation is detected to be out of operation, a virtual bay put-in operation is performed.

In practical application, when a certain entity interval (i.e. an entity measurement and control device) of the transformer substation fails or needs to be overhauled, the entity interval needs to be controlled to be withdrawn from operation.

In this embodiment, when the cluster measurement and control detects that the first entity interval exits, the virtual interval input operation may be executed. The first inter-entity interval may be one or a plurality of.

In one embodiment of the present application, to determine whether a first entity interval in a substation is out of operation, cluster measurement and control may perform the following steps, which are described in detail below:

detecting heartbeat messages sent by the first entity at intervals based on a set duration;

In this embodiment, the set duration may be set according to actual needs, which is not limited herein.

The heartbeat message may be a GOOSE heartbeat message.

In this embodiment, when the cluster measurement and control does not detect the heartbeat message sent by the first entity interval within the set duration, the cluster measurement and control may determine that the first entity interval has exited the operation, so the cluster measurement and control may execute the virtual interval input operation.

In one embodiment of the present application, when the cluster measurement and control detects the heartbeat message sent by the first entity interval within the set duration, it may be determined that the first entity interval is not out of operation, that is, the first entity interval is still in an operation state, so that the cluster measurement and control does not need to execute the virtual interval input operation.

In this embodiment of the present application, because the cluster measurement and control stores the correspondence between different entity intervals and different virtual intervals in advance, the virtual interval input operation specifically refers to inputting into use a first virtual interval corresponding to a first entity interval.

In another embodiment of the present application, the cluster measurement and control may specifically perform the virtual interval input operation through S201 to S202 as shown in fig. 3, which is described in detail as follows:

in S201, the first virtual interval is put into a virtual interval put position in a virtual substation scene, and a communication module corresponding to the first virtual interval is started.

In this embodiment, when the cluster measurement and control detects that the first entity interval in the substation exits, the first virtual interval corresponding to the first entity interval may be put into a virtual interval put position in a virtual substation scene, and a communication module corresponding to the virtual interval is started to start a communication task of a manufacturing message specification (Manufacturing Message Specification, MMS) of the first virtual interval, so that a process start waiting time for the first virtual interval to be put into use is reduced, and working efficiency of the cluster measurement and control is improved.

It should be noted that the virtual delivery location may be the same location in the virtual substation scenario as the location of the first entity interval in the actual substation scenario.

In S202, when it is detected that the first entity interval is not in the site-controlled layer network of the substation, the first virtual interval is accessed to the site-controlled layer network.

In practical application, when detecting that the first entity interval fails or needs to be overhauled, an operation and maintenance person needs to cut off the first entity interval from the station control layer network of the transformer substation, namely, control the first entity interval to exit the station control layer network.

Based on this, in this embodiment, when the cluster measurement and control detects that the first entity interval is not in the station-controlled layer network of the substation, the first virtual interval is accessed to the station-controlled layer network.

In one embodiment of the present application, the cluster measurement and control may specifically execute step S202 through S301 to S303 as shown in fig. 4, which is described in detail as follows:

in S301, a network address table of the station-controlled layer network is obtained; wherein the network address table stores network addresses of respective devices provided in the station-controlled layer network.

In this embodiment, in order to avoid network address collision of devices in the station control layer, the cluster measurement and control needs to acquire a network address table of the station control layer network in real time.

The network address table may be an address resolution protocol (Address Resolution Protocol, ARP) table, among others.

The network address may be an internet protocol (Internet Protocol, IP) address.

In this embodiment, after the cluster measurement and control acquires the network address table, it is required to detect whether a target network address of the first entity interval exists in the network address table.

In one embodiment of the present application, the cluster measurement and control may perform steps S302 to S303 when it is detected that there is no target network address of the first entity interval in the network address table.

In another embodiment of the present application, when the cluster measurement and control detects that the target network address of the first entity interval exists in the network address table, the first entity interval exit failure is indicated, so the cluster measurement and control may output information for prompting the operation and maintenance personnel of the first entity interval exit failure.

In S302, when it is detected that there is no target network address of the first entity interval in the network address table, a virtual network address corresponding to the target network address is generated.

In S303, the virtual network address is associated with the first virtual interval, and the first virtual interval is accessed to the station-controlled layer network.

In this embodiment, when the cluster measurement and control detects that the target network address of the first entity interval does not exist in the network address table, it is stated that the first virtual interval may be accessed to the control layer network instead of the first entity interval, so the cluster measurement and control may generate a virtual network address corresponding to the target network address of the first entity interval, associate the virtual network address with the first virtual interval, and access the first virtual interval to the control layer network.

In one implementation manner of this embodiment, the cluster measurement and control may use a virtual IP technology to simulate the target network address to obtain a virtual network address.

In S102, when the virtual interval input operation is detected, a first number of a first virtual interval input to operation is acquired, and the first number is written into a shared memory.

In the embodiment of the present application, when the cluster measurement and control detects the virtual interval input operation, the first number of the first virtual interval input operation may be obtained, and the first number may be written into the shared memory of the cluster measurement and control.

The first number is the same as the entity number of the first entity interval.

In one implementation manner of the embodiment of the present application, the cluster measurement and control may write the first number into the shared memory of the cluster measurement and control according to a bit offset manner.

In this embodiment of the present application, the cluster measurement and control may send the first number to the process layer plug-in through the bus, and write the first number into the process layer plug-in.

In S103, when it is detected that the first number is the same as a preset number stored in advance by a process layer plug-in cluster measurement and control of the substation, the process layer plug-in is controlled to output message information for indicating that the first virtual interval is put into use.

The process layer plug-in stores the setting numbers of different virtual intervals in advance.

In this embodiment of the present application, when the cluster measurement and control detects that the first number is the same as the preset number stored in the variable process layer plug-in, it is indicated that the first virtual interval may be put into use, so the cluster measurement and control may control the process layer plug-in to output the message information for indicating that the first virtual interval is put into use, and open a GOOSE message sending function corresponding to the first virtual interval.

As can be seen from the above, according to the virtual interval input method provided by the embodiment of the present application, when the first entity interval in the substation is detected to be out of operation, virtual interval input operation is performed; when virtual interval input operation is detected, a first number of a first virtual interval input operation is obtained, and the first number is written into a shared memory; when the first number is detected to be the same as a preset number stored in the process layer plug-in cluster measurement and control of the transformer substation, the process layer plug-in is controlled to output message information for indicating that the first virtual interval is put into use. Compared with the prior art that all virtual intervals are fixedly operated, the method provided by the application is that when a certain entity interval is detected to be withdrawn from operation, the corresponding virtual interval is put into operation, and the operation cost is reduced.

Referring to fig. 5, fig. 5 is a schematic diagram of a virtual space input method according to another embodiment of the present application. In contrast to the embodiment corresponding to fig. 1, the method for inputting the virtual space may further include S401 to S404, which are described in detail below:

in S401, receiving a virtual interval exit instruction; the virtual interval exit instruction carries a second number of a second virtual interval which needs to be used for exit.

In S402, the second number is deleted from the shared memory, and the virtual network address corresponding to the second virtual interval is logged out.

In S403, the process layer plug-in is controlled to stop outputting the message information in the set format.

In S404, when a heartbeat packet sent by a second entity interval corresponding to the second virtual interval is detected, closing a communication module corresponding to the second virtual interval, so as to complete the operation of exiting from use of the second virtual interval.

In this embodiment, when a certain entity interval has a recovery operation condition, in order to put the entity interval into use, the virtual interval corresponding to the entity interval in the cluster measurement and control needs to be taken out of use, so that an operation and maintenance personnel can send a virtual interval take-out instruction to the cluster measurement and control. The virtual interval exit instruction carries a second number of a second virtual interval which needs to be used for exit.

When the cluster measurement and control detects a virtual interval exit instruction, in order to thoroughly cut off the second virtual interval from the substation site-controlled layer network, the cluster measurement and control needs to delete the second number of the second virtual interval from the shared memory of the cluster measurement and control, and cancel the virtual network address corresponding to the second virtual interval from the substation site-controlled layer network.

In one implementation of this embodiment, the cluster measurement and control may delete the second number from the shared memory in a bit-offset manner.

In this embodiment, when the cluster measurement and control deletes the second number from the shared memory, in order to avoid the influence of the cluster measurement and control on the automation system, the process layer plug-in may be controlled to stop outputting the message information in the set format. That is, when the second virtual interval is withdrawn from use, the GOOSE message sending function corresponding to the second virtual interval is withdrawn simultaneously, so that the CPU resource is saved, and the reliability of cluster measurement and control is improved.

The setting format may be GOOSE format.

In this embodiment, after the cluster measurement and control process layer plug-in stops outputting the message information in the set format, the operation and maintenance personnel may put into use the second entity interval corresponding to the second virtual interval.

Based on the above, the cluster measurement and control can detect whether the heartbeat message sent by the second entity at intervals is received or not in real time.

In this embodiment, when the cluster measurement and control detects the heartbeat message sent by the second entity interval, it indicates that the second entity interval is put into use and operates normally, and at the same time, the second virtual interval is put into zero clearance, so the cluster measurement and control can close the communication module corresponding to the second virtual interval, that is, stop the MMS communication task of the second virtual interval, so as to recover the CPU resource.

As can be seen from the above, in the virtual interval input method provided in this embodiment, a virtual interval exit instruction is received; the virtual interval exit instruction carries a second number of a second virtual interval which needs to be used for exit; deleting the second number from the shared memory, and canceling the virtual network address corresponding to the second virtual interval; controlling the process layer plug-in to stop outputting message information in a set format; and when the heartbeat message sent by the second entity interval corresponding to the second virtual interval is detected, closing the communication module corresponding to the second virtual interval so as to finish the operation of exiting the second virtual interval. The method provided by the embodiment ensures that the virtual interval is thoroughly cut off from the network after the virtual interval is withdrawn from use, and improves the withdrawal success rate of the virtual interval.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
