In an embodiment of the present invention, described process layer devices is merge cells intelligent terminal.
Compared to prior art, the present invention has following beneficial effect: the present invention, to simplification work on the spot amount, ensures vehicle-mounted removable intelligent substation protection system rapid deployment and normally run to play vital effect.
Accompanying drawing explanation
Fig. 1 is the automatic detection and the check system structured flowchart that the present invention is based on vehicle-mounted mobile station electrical secondary system.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is specifically described.
As shown in Figure 1; in a kind of 110kV of the present invention vehicle moving intelligent substation, the routine configuration of secondary device comprises all kinds of process layer, wall and station level equipment; wherein station level monitoring background host computer generally selects industrial computer; its performance is comparatively stable; the automatic checkout system of secondary device of the present invention itself is positioned at station level network, by completing the automatic detection of the complete electrical secondary system of mobile radio station to the monitoring of all kinds of merge cells of process layer intelligent terminal, all kinds of protective device of wall and secondary communication loop (fiber optic network) each other thereof.
The monitoring to its state is used for mainly through the following information of timing acquiring for merge cells and intelligent terminal:
Consider to be directly connected to station level network to merge cells and intelligent terminal at present, its on-line monitoring information directly cannot be uploaded to analysis platform, the access for this reason by adopting supporting measure and control device to complete merge cells and the above-mentioned monitoring information of intelligent terminal.
Monitoring to its state is used for mainly through the following information of timing acquiring for protective device:
Due to itself direct access station control layer network of wall protective device, the analysis platform of mobile radio station electrical secondary system, by station level network, directly accesses detection platform the status monitoring information of protective device according to IEC61850 communication protocol.
Automatic detection for secondary circuit mainly comprises the monitoring of physics and logical links communications status.
No matter monitoring wherein for physical link is that (transmit leg and the corresponding physical equipment of recipient are protective device or merge cells and intelligent terminal or switch, and the physical link of its optical fiber communication comprises transmit leg optical fiber interface, point-to-point optical fiber, recipient's optical fiber interface three parts nothing more than.Meanwhile, the analysis of optical networking port communications abnormal failure may be caused from device damage, there are abnormal three aspects in device self, interface card, optical fiber interface nothing more than for they, wherein device self is such as when installation's power source occurs abnormal, occurs abnormal by the fiber optic network port communications causing device all; Interface card is such as: when device optical fiber interface plug-in unit occurs abnormal, occurs abnormal by the fiber optic network port communications causing plug-in unit all; Optical fiber interface such as when the single optical fiber interface of device occurs abnormal, will cause this optical fiber interface communication to occur abnormal.
From the principle that optical fiber communication monitors, the function for monitoring of optical fiber communication completes recipient, when optical fiber link is abnormal, recipient cannot receive data normally, thus judge that optical fiber link there occurs exception, but in fact recipient directly cannot judge that problem has appearred in that participation link of link, namely transmit leg optical fiber interface cannot be navigated to, communication link or recipient's optical fiber interface have sent exception, should be noted that simultaneously, conveniently realize optical fiber link Stateful Inspection, the link abnormal alarm that receiving equipment sends needs clear and definite physical concept, general employing is for the principle of transmitting apparatus.
The optical fiber communication of process layer devices may be abnormal by plug-in unit extremely, or device is abnormal, like this in unit exception process, in whole mobile substation, corresponding link abnormal signal is produced by by a lot of equipment, secondary automatic detecting platform is exactly by these link abnormal signals, carries out the accurate location of link exception.
In order to realize this function, definition two structures are needed to come storing fiber optic link physical port information and optical fiber link abnormal information,
Fiber port structure:
Struct
{
Device; // device is numbered
Slot; // plug-in unit numbering or module numbering (switch)
Fiber; // optical fiber is numbered
}PORT
Optical fiber link anomaly sxtructure:
Struct
{
PORTsource; Data sending terminal mouth
PROTroute1-N; Switch switching port
PORTdestination; Data receiver port
}
Electrical secondary system automatically detects backstage and constructs above structure information, and real-time reception optical fiber link abnormal information, whether the transmit port analyzing all link exception informations is identical with receiving port, when the abnormal corresponding transmit port (comprising the switch switching port that forward direction is reviewed) of all optical fiber links is identical, then show that exception has appearred in the point-to-point optical fiber of this data sending terminal mouth or its correspondence or receiving port.
For the monitoring of logical links mainly for the on-line checkingi of network service content validity, be used for guaranteeing that the process layer communication configuration of Practical Project and the integrated configuration of SCD are consistency.At present according to IEC61850 standard-required, process once GOOSE and SV in data exchange process, not only exchange communication data, also swap data configuration, so just create condition for the on-line monitoring of logical links communication, on this basis, the configuration sent by checking and the integrated configuration consistency of SCD, the logically transmission of proof procedure bed device configures, receives the consistency configured with the integrated configuration of SCD.
GOOSE receives information
SV receives information
Mobile radio station secondary detects automatically, verifying bench constantly reads GOOSE and SV message by process-level network, analyze the SCD configuration information (the blue portion content in above form) in message, compare with the corresponding configuration information in SCD file, when noting abnormalities, send alarm signal.
The course of work:
Vehicle-mounted mobile substation electrical secondary system detects automatically, verify platform imports SCD file by configuration tool, and the information extraction of the on-line monitoring such as light intensity, temperature is entered database, completes the foundation of mobile substation secondary device status monitoring model;
Vehicle-mounted mobile substation electrical secondary system detects automatically, verify platform is displayed on picture by the information of drawing tools by the on-line monitoring of electrical secondary system;
Vehicle-mounted mobile substation electrical secondary system detects automatically, verify the limit value data of platform configuration monitoring information, carries out Threshold Crossing Alert when monitoring information is out-of-limit;
Vehicle-mounted mobile substation electrical secondary system detects automatically, verify the service end of platform and proterctive equipment and wall measure and control device sets up MMS and is connected, real-time reception Monitoring Data.
Be more than preferred embodiment of the present invention, all changes done according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
