Description
Technical Field
The invention belongs to the technical field of intelligent substations, and particularly relates to an intelligent substation relay protection test expander, a protection debugging method and electronic equipment for realizing the method.
Background
The relay protection is an important measure for detecting faults or abnormal conditions occurring in the power system so as to send out alarm signals or directly isolate and remove fault parts. The relay protection test is a process of testing relay equipment by respectively generating input (output) signals through a main loop and an auxiliary loop so as to determine safety.
The intelligent substation is an indispensable construction content as an important foundation and node support of a strong intelligent power grid. The relay protection of the intelligent substation is already standardized and specified, such as technical specification of relay protection of the intelligent substation (Q/GDW 441-2010). When a relay protection test is performed on an intelligent substation, an intelligent substation protection tester is generally used.
However, in the existing intelligent substation protection tester, the number of GOOSE/SV sending ports is 3, and for protection verification of complex logic, for example, a backup automatic switching device, three SV sampling ports connected directly and three GOOSE sampling ports connected directly and a networking port are often needed. Particularly, for the additional installation work of the spare power automatic switching device in the operating transformer substation, the protection verification cannot be realized through the actual displacement on site, and only through the simulation of a tester, the number of the transmitting ports of the conventional tester GOOSE/SV cannot meet the logic verification of the spare power automatic switching device.
In addition, a large amount of data transmission exists between the spacing layer and the process layer of the intelligent substation, and a sending end and a receiving end, so that excessive broadcasting of an interactive network is easily caused when the number of ports is too large; when the data is collected by a Virtual Local Area Network (VLAN) device, if the VLAN state parameters are set unreasonably, the data transmission integrity in the test process is affected greatly, and even the test function cannot be realized.

Detailed Description
The invention is further described with reference to the following drawings and detailed description.
Referring to fig. 1, fig. 1 is a schematic diagram of an appearance basic architecture of an intelligent substation relay protection debugging extender according to an embodiment of the present invention.
In fig. 1, the expander 1 is shown to include an expansion port 2, a network card port 3, a bluetooth port 4, a power module 5, a status indicator light 6, an ac power plug 7, and a switch button 8.
As a more specific example, the expansion port 2 is 6 LC optical fiber interfaces, the network card port 3 is a hundred mega RJ45 port, and the bluetooth port 4 is a dual-mode bluetooth communication component;
the power module 5 comprises an energy storage unit, and the alternating current power plug 7 is used as a charging wire to charge the energy storage unit.
In a specific embodiment, the expander is provided with an energy storage module and a power supply module, and can perform VLAN division to meet GOOSE/SV information transmission. The expander can be connected with a GOOSE/SV sending port of the intelligent relay protection tester to expand the sending port so as to meet the debugging requirement of complex protection logic. The expander can be connected with a computer through a hundred-million RJ45 port and can be set, and different scene requirements are met. In addition, the transmission delay of the expander is less than 10us, the expander has a mirror image function and can be provided with delay compensation so as to meet the requirement of GOOSE/SV information transmission, the optical port communication rate is self-adaptive to 100M/1000M, and the interface type is an LC interface.
In the intelligent substation relay protection debugging expander, the intelligent substation relay protection debugging expander further comprises an energy storage module and a power supply module, wherein the power supply module supplies power to the device through a charging wire and charges the device for energy storage.
In the relay protection debugging expander for the intelligent substation, the remote transmission module is Bluetooth.
According to the intelligent substation relay protection debugging expander, the setting tool can be opened through a mobile phone or a computer.
It is to be understood that, in the present invention, port for short, VLAN for short, for "Port" and wireless lan, and ID means an identifier. Thus, PVID can be understood as the wireless local area network ID of the port, i.e. PVID.
To further implement the above process, next, on the basis of fig. 1, see fig. 2. Fig. 2 is a schematic connection diagram of an application scenario of the intelligent substation relay protection debugging expander in fig. 1.
In fig. 2, the expander includes a communication module and an expansion port; the expansion port comprises a plurality of fiber optic interfaces; the communication module comprises a Bluetooth port and a hundred-million RJ45 port;
the extender further comprises a PVID setting module;
the expander is communicated with a handheld mobile terminal through the Bluetooth port, or communicated with a host computer through the hundred million RJ45 port;
the expander is connected to an LC optical fiber interface of the intelligent protection tester of the transformer substation through a first optical fiber interface in the plurality of optical fiber interfaces;
when the PVID setting module detects that the expander is successfully connected with the LC optical fiber interface of the intelligent protection tester of the transformer substation through the first optical fiber interface, displaying a PVID setting interface on a display interface of the handheld mobile terminal or the host computer;
the PVID setting interface is used for setting VLAN division parameters of other optical fiber interfaces except the first optical fiber interface in the plurality of optical fiber interfaces.
Specifically, the VLAN partition parameter includes a PVID and a VLAN tag of each optical fiber interface; the PVID is a continuously increasing or identical ID number.
The number of VLAN tags can be understood as how many groups of VLANs are divided, i.e. the packet or segment size of the VLAN.
As a simple example, taking the expansion port 2 shown in fig. 1 as 6 LC fiber interfaces as an example, the PVID of 5 LC fiber transmission interfaces (another is used as a receiving port) in the 6 LC fiber interfaces included in the expansion port 2 shown in fig. 1 may be set as follows:
1-2-3-4-5；1-2-2-3-4；1-1-1-1-1；
it should be noted that, as portability and convenient adaptation and manufacture of the expansion device, all the fiber interfaces included in the expansion port 2 in fig. 1 are identical in structure and each has a transmitting function and a receiving function, that is, the expansion port is a receiving port or a transmitting port;
however, in a specific application, one of the ports is determined to be a receiving port and the other remaining ports are determined to be transmitting ports through connection monitoring.
Specifically, in fig. 2, when the PVID setting module detects that the extender is successfully connected to the LC fiber interface of the substation intelligent protection tester through the first fiber interface, the first fiber interface is a receiving port;
and the other optical fiber interfaces except the first optical fiber interface in the plurality of optical fiber interfaces are transmitting ports.
If the PVID setting module detects that the expander is connected with the LC optical fiber interface of the intelligent protection tester of the transformer substation through the first optical fiber interface overtime, an overtime prompt is displayed on a display interface of the handheld mobile terminal or the host computer, and the overtime prompt reminds a tester to replace other optical fiber interfaces to be used as the first optical fiber interface again to execute connection.
Obviously, by means of the detection-configuration mode, a tester does not need to pay attention to which port is selected to be connected to the intelligent protection tester (data transmission device) of the transformer substation or which port is selected to be connected to the data acquisition device (data receiving device) during testing; meanwhile, when the expander is manufactured, only a plurality of ports with the same performance need to be configured, and the ports do not need to be distinguished;
meanwhile, even if a certain port has functional errors, the subsequent function realization of the expansion port is not influenced; even if only the transmission function (reception function is missing or malfunctioning) remains, a certain port can still be used as the transmission function (when it is used as the reception function, an erroneous replacement is prompted).
Therefore, the embodiment of the invention can greatly improve the test integrity and ensure the use convenience.
After the port connection is normal, the expander is successfully connected to the LC optical fiber interface of the intelligent protection tester of the transformer substation through the first optical fiber interface in the plurality of optical fiber interfaces, and then the expander is connected to the N groups of local area network data acquisition equipment through the other N optical fiber interfaces except the first optical fiber interface in the plurality of optical fiber interfaces. The intelligent protection tester is used as a data sending end and the data acquisition equipment is used as a data receiving end relative to the transformer substation. And N is a positive integer greater than 2.
Reference is next made to fig. 3. The PVID setting interface is used for setting VLAN division parameters of other N optical fiber interfaces except the first optical fiber interface in the plurality of optical fiber interfaces.
As mentioned above, the extender is connected to N groups of local area network data acquisition devices through N other optical fiber interfaces of the plurality of optical fiber interfaces except the first optical fiber interface.
In practical applications, in order to meet the requirements of real-time performance and high efficiency of the information of the intelligent substation equipment, it is necessary to logically divide the local area network equipment (for example, the data acquisition equipment mentioned in this embodiment) into a plurality of network segments through a virtual local area network VLAN so as to implement virtual packet data exchange (transmission and reception).
A number of similar VLAN configuration schemes already exist in the prior art, as follows:
huang Heng, qian Xingrong, fangfan. Intelligent substation VLAN setup solution analysis [ J ]. Electronic world, 2014 (15): 59-59. DOI.
However, most of these solutions need to be adapted based on the actual experience of the field personnel and meeting the corresponding rules, and are not suitable for human-computer interaction of the extender.
In view of the above, the present embodiment provides a simple method for dividing and allocating packet IDs of lan devices.
In particular, see fig. 3. The PVID setting interface is configured to set VLAN partition parameters of N optical fiber interfaces other than the first optical fiber interface, and specifically includes the following steps:
s501: setting the number of VLAN marks;
in practical application, the number of VLAN tags can be dynamically set and updated, and specifically can be performed according to the number of existing ports.
As an example, when the number of ports is M, the number N of VLAN tags is an integer greater than or equal to M/2;
as a simple example, taking the expansion port 2 shown in fig. 1 as 6 LC fiber interfaces, M =6, n =3;
that is, the number of VLAN tags is 3, that is, all the ports can be divided into 3 groups at most, and the tags are set as A-B-C;
s502: setting the PVID of each optical fiber interface;
as mentioned above, the PVID is a continuously increasing or identical ID number.
Continuing with the example that the expansion port 2 in fig. 1 is 6 LC fiber interfaces, the PVID of 5 LC fiber transmission interfaces (another one is used as a receiving port) in the 6 LC fiber interfaces included in the expansion port 2 in fig. 1 may be set as follows:
1-2-3-4-5；1-2-2-3-4；1-1-1-1-1；
s503: and updating the VLAN marks connected with the optical fiber interfaces corresponding to the adjacent or same PVID to be the same according to the number of the VLAN marks.
Taking the PVID as an example, one implementation manner of the VLAN tag is:
1(A)-2(A)-3(B)-4(B)-5(C)；
1(A)-2(B)-2(B)-3(C)-4(C)；
1(A)-1(A)-1(B)-1(B)-1(C)；
as a general principle, it is at least ensured that VLAN tags of fiber interface connections corresponding to two adjacent or identical PVIDs are updated to be identical.
On the basis of the above-mentioned formula, the material can be used,
after the step S503, the method further includes the steps of:
s504: after a predetermined period of time, the number of VLAN tags is updated, and the process returns to step S503.
Here, the updating of the number of VLAN tags may be performed by increasing N to 4.
Based on the configuration, when data is transmitted, the VLAN marks the same optical fiber interface A and the same optical fiber interface B as a main transmitting port and a standby transmitting port; when the time delay of sending data to the local area network acquisition equipment through the optical fiber interface A exceeds a preset value, the data sending of the optical fiber interface A is kept, and meanwhile the time delay data are sent to the local area network acquisition equipment through the optical fiber interface B.
It should be noted that the "active/standby" is operated simultaneously, which is different from the meaning of one failing and another taking over as commonly mentioned in the prior art.
On the basis, as a further improvement, when the delay of sending data to the local area network acquisition device by at least one optical fiber interface exceeds a predetermined value, the number of the VLAN tags is updated, and the step S503 is returned.
Based on fig. 1-3, reference is next made to fig. 4.
Fig. 4 is a schematic flow chart of an intelligent substation relay protection debugging method implemented based on the intelligent substation relay protection debugging extender shown in fig. 1.
In fig. 4, the method includes steps S910 to S940, and each step is implemented as follows:
s910: the expander is communicated with a handheld mobile terminal through a Bluetooth port, or communicated with a host computer through a hundred-million RJ45 port;
s920: connecting the expander to an LC optical fiber interface of a substation intelligent protection tester through a first optical fiber interface in a plurality of optical fiber interfaces;
s930: judging whether the connection is successful;
if not, displaying an overtime prompt on a display interface of the handheld mobile terminal or the host computer, reminding a tester of replacing other optical fiber interfaces to be used as the first optical fiber interface again for connection execution, and returning to the step S920;
if yes, displaying a PVID setting interface on a display interface of the handheld mobile terminal or the host computer, and entering step S940;
s940: setting VLAN division parameters of other optical fiber interfaces except the first optical fiber interface in the plurality of optical fiber interfaces on the PVID setting interface;
the VLAN division parameter comprises VID and VLAN mark of each optical fiber interface.
Specifically, the step S940 includes:
s401: setting the number of VLAN marks;
s402: setting the PVID of each optical fiber interface;
s403: and according to the number of the VLAN marks, the VLAN marks connected with the optical fiber interfaces corresponding to the adjacent PVIDs are updated to be the same.
S404: after a predetermined period of time, the number of VLAN tags is updated, and the process returns to step S403.
After step S940, the method further includes:
s950: and when the delay of at least one optical fiber interface for sending data to the local area network acquisition equipment exceeds a preset value, updating the number of the VLAN marks.

5. even if a certain port has functional errors, the subsequent function realization of the expansion port is not influenced; even if only the transmission function (reception function is missing or malfunctioning) remains, a certain port can still be used as the transmission function (when it is used as the reception function, an erroneous replacement is prompted).
