Abstract
The invention relates to a synchronization network split type protection calibration instrument for an intelligent transformer station. The protection calibration instrument is characterized in that a plurality of microcomputer protection check meters are arranged next to combination units needing test does adding; and alternating-current analog quantities needing to be inputted are inputted into the combination units by secondary test wires. All microcomputer protection check meters in a distributed mode are connected by networking by RJ45 network cables, optical fibers or in wireless network mode. All the dispersed microcomputer protection check meters are combined into the integrated one by networking and one designated host controls other microcomputer check meters to output various alternating current quantities synchronously by networking, thereby realizing integrated calibration of all combination units and protection units of the intelligent transformer station. Compared with the prior art, all combination units are contained during equipment calibration and little difference with conventional transformer station protection calibration is caused, so that the maintenance staff can carry out work easily and the equipment can be repaired easily.
Description
Technical field
The present invention relates to a kind of checkout equipment, the split type protective calibration instrument of especially a kind of intelligent substation synchronizing network.
Background technology
Along with the penetration and promotion of intelligent substation, electronic current mutual inductor (ECT) and optic current transformer (OCT) start to use in a large number.Along with the progress of technology, the various technical schemes of intelligent substation are also at diversified development.Present stage, intelligent substation had one to be carry out device verification in merge cells rear end by intelligent substation digit check instrument output optical fibre message information; The shortcoming of this method is, for a set of protective device, protective device is positioned at indoor, and merge cells is positioned at outdoor; In checking procedure, Microcomputer Protection tester is placed on outdoor merge cells place and adds fault amount, and the action situation of the check protection device that the maintainer of indoor can only be passive, secondary device; On the other hand, the protective device for the high voltage electric equipment of more than 110kV often needs multiple merge cells to provide of ac information, such as, need electric current merge cells to provide ac flow information, needs voltage merge cells to provide voltage of ac information.The electric current merge cells of multiple different interval equipment is then needed to provide magnitude of current information for differential protection (tranformer protection, bus differential protecting).And these amalgamated units often disperse is arranged in outdoor everywhere, if now want to carry out verifying, need the test wire of common microcomputer calibrating instrument to extend, tens can be extended under extreme case to rice up to a hundred; In this case cause site test wiring complicated on the one hand, workflow is loaded down with trivial details; Also there is potential safety hazard in longer test connecting line on the other hand; If longer test wire easily causes the deviation of test figure under being arranged in strong magnetic field circumstance.Other shortcoming is not included by merge cells when device verifies, and device verification is not comprehensive, and this method and conventional substation protective calibration are distinguished greatly, and maintainer is not easy left-hand seat; Therefore; design is a kind of to be included merge cells when device verifies, and distinguishes not quite with conventional substation protective calibration, the easy left-hand seat of maintainer; equipment is easy to the split type protective calibration instrument of intelligent substation synchronizing network safeguarded, is the current technical issues that need to address.
Summary of the invention
Technical matters to be solved by this invention is to provide one and is included by merge cells when device verifies; and distinguish not quite with conventional substation protective calibration; the easy left-hand seat of maintainer, equipment is easy to the split type protective calibration instrument of intelligent substation synchronizing network safeguarded.
The technical scheme that the present invention solves its technical matters is:
The split type protective calibration instrument of intelligent substation synchronizing network, arrange that multiple stage Microcomputer Protection tester is placed in the merge cells side needing to add tested number nearby, merge cells is inputed to by needing the ac analog passed into by second trial line, each Microcomputer Protection tester that distribution is arranged is by RJ45 netting twine, optical fiber or wireless network mode carry out networking connection, formed a whole by the Microcomputer Protection tester of networking by each dispersion, the various of ac of other microcomputer calibrating instrument of the host computer control of specifying by networking synchronism output, thus realize each merge cells of intelligent substation, the entirety verification of protective device.
Scheme is selected as one of the present invention; the described main frame of specifying is computer; split Microcomputer Protection tester is arranged nearby at each merge cells; at the indoor layout Communication Gateway of transforming plant protecting and host computer; each split protective calibration instrument is connected with host computer through protecting indoor Communication Gateway by communication networks such as RJ45 netting twine, optical fiber or wireless networks, and the verification of protective device carries out synchronism output test by protecting indoor electric brain server by each split type protective calibration instrument of programmed control.
Select scheme as one of the present invention, the described main frame of specifying is Microcomputer Protection tester, arranges split type Microcomputer Protection test instrument nearby at each merge cells; Arrange identical Microcomputer Protection test instrument in protection room, indoor, indoor Microcomputer Protection test instrument can be main frame by programming; Outdoor each split type Microcomputer Protection test instrument is by communication network and the networkings of indoor Microcomputer Protection test instrument such as RJ45 netting twine, optical fiber or wireless networks; Indoor Microcomputer Protection test instrument controls other each split type Microcomputer Protection testers and realizes simultaneous test.
Compared with prior art, main innovate point of the present invention: 1, original transformer station Microcomputer Protection tester is all separate unit independently device, multiple stage Microcomputer Protection tester by each independently Microcomputer Protection test instrument networking in transformer station, thus is constituted an entirety by the present invention; 2, become an adult by the networking of Microcomputer Protection tester, synchronous on test exports of the Microcomputer Protection tester that can realize each split, when solving intelligent substation each merge cells dispersed placement, separate unit microcomputer calibrating instrument cannot meet a difficult problem for testing requirements; 3, in the present invention, the network channel of each split Microcomputer Protection tester just can install in capital construction or rebuilding construction, can no longer lay interim network channel during test; 4, the present invention is not only confined to the intelligent substation pattern that routine transformer adds merge cells, for the intelligent substation of other networking modes, also can realize verifying the entirety of protective device by the split type Microcomputer Protection tester of synchronizing network, the especially differential simultaneous test waiting protection; 5, two schemes of the present invention, both can arrange special host computer, also the split type Microcomputer Protection tester of same-type can be used as main frame.Each split type Microcomputer Protection tester, when not carrying out Networking test, all can complete separately Microcomputer Protection verification project.Any split type Microcomputer Protection tester itself all has independently protective calibration function.
