Background technology
Modern intelligent substation has been applied a large amount of computer technologies, the communication technology and sensor technology; developing rapidly of new technology; the develop rapidly of the Substation Automation System that brings with it; they are take communication network technology as basis; various protective relaying devices, aut.eq., RTU (remote terminal) and dispatching terminal are coupled together; for making transformer station realize the economical operation of high-quality, high-speed, high flexibility, secondary equipment of intelligent converting station descends exoergic to optimize to a great extent this problem on the spot.Digital transformer substation is transferred on the spot platform and carrier is provided for secondary equipment of intelligent converting station; secondary device is transferred on the spot; with the protection of dispersed placement, monitoring, metering, by fiber optic network, be closely linked; the dispersion of formation function, physical dispersion, scattered risks, information are concentrated, are gathered and share; improve the antijamming capability of whole system, reduce maintainer's searching work.
Secondary device is transferred on the spot, especially intelligent terminal is transferred, cable connection has been compressed between primary equipment and outdoor cabinet, the construction costs of cable descends obviously, process layer devices to master-control room equipment room adopts the optical fiber and digital transmission, avoided long cable poor anti jamming capability, master-control room equipment must be with cable except power supply, and other are all optical fiber outlet or grid line.
Under this background, the debugging of the protective relaying device that site is installed is about to face series of problems, if distinct issues are check problems of completing secondary device of efficiently and accurately under outdoor abominable atmospheric environment.Particularly wait northeastward extreme area, winter, outdoor temperature was very low, and the tester is not suitable for working out of doors continuously, therefore needed a kind of new method of testing of exploratory development, made the tester in indoor debugging and the check that just can complete outdoor equipment.
The utility model content
For above-mentioned the deficiencies in the prior art part; the utility model provides a kind of remote debugging system of site mount type protective relaying device, and purpose is debugging and the verification that realizes the protective relaying device of in the intelligent substation pulpit, site being installed for being.
The utility model is achieved through the following technical solutions:
A kind of remote debugging system of site mount type protective relaying device is that cabinet inside is provided with secondary device and light shifter out of doors, is provided with Debugging message main frame and digital protecting tester in transformer station's master-control room; Secondary device output debug port is connected on the Debugging message main frame of master-control room through switch; Secondary device is connected on other secondary devices by optical fiber, and secondary device also and be connected with standby optical fiber between the digital protecting tester.
Advantage of the present utility model and effect are:
Can realize debugging and the verification of the protective relaying device of in the intelligent substation pulpit, site being installed.Wait northeastward cold district; when the protective relaying device that in transformer station, site is installed is debugged; the staff is at electric current, the standard voltage value of controlling the setting of in-house operation relay-protection tester; by the optical fiber long-distance transmissions, digital signal is delivered to the protective relaying device erecting stage; the response condition of monitoring and protection devices type in pulpit, solved the problem of tester in the outdoor continuous work of cold simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model site mount type protective relaying device remote debugging system schematic diagram.
Embodiment
The utility model is a kind of remote debugging system of site mount type protective relaying device.Be that cabinet inside is provided with secondary device and light shifter out of doors, be provided with Debugging message main frame and digital protecting tester in transformer station's master-control room, the protective device swap data of installing by reserving optical fiber and site.Secondary device output debug port is connected on the Debugging message main frame of master-control room through switch; Secondary device is connected on other secondary devices by optical fiber, and secondary device also and be connected with standby optical fiber between the digital protecting tester.
The remote debugging method of site mount type protective relaying device described in the utility model; need to be when transformer substation construction; the cabinet protective device is to reserving and lay test optical fiber between master-control room out of doors; light shifter is set up in outdoor cabinet inside, realizes on the secondary device device moving the switching between optical fiber and standby optical fiber.Described optical fiber switching mode, can adopt the Long-distance Control switching., if there is no light shifter, when secondary device is debugged, can carry out the photoswitch manual switchover to outdoor cabinet by artificial plug optical fiber by the tester.Secondary device is exported debug port, is connected to the main frame of master-control room through switch, and this Debugging message main frame can be regarded " distant place liquid crystal " of secondary device as, can obtain the analog quantity, switching value, the report that monitor secondary device.In the time need to debugging the secondary device of outdoor cabinet, optical fiber is transferred to standby optical fiber, utilize the digital protecting tester dosage of master-control room; Check the feedback information of secondary device by the Debugging message main frame, reach debugging purpose.The remote debugging system schematic diagram as shown in Figure 1.
The remote debugging method of site mount type protective relaying device is as follows:
(1) artificial or automatic switchover secondary device SV/GOOSE optical fiber is to standby optical fiber;
(2) the digital protecting tester imports tested device CID file, 61850 message informations between configuration and equipment under test;
(3) digital protecting tester simulation electric system normal load, provide the current-voltage sampling value to tested device, the tester checks on secondary device the analog quantity of sending backstage on the Debugging message main frame of master-control room, judge between digital protecting tester and tested device, whether communication is normal, if there is no sampled value, need to check fiber cabling or the configuration of digital protecting tester, confirm that both data communications are normal;
(4), with digital protecting tester software simulation electric power system fault, check the secondary device response on the Debugging message main frame, carry out the secondary device function debugging.
