In above accompanying drawing: 1, the first R-T unit; 2, the second R-T unit; 3, the first sending module; 4, the first receiver module; 5, the second sending module; 6, the second receiver module; 7, testing fixture; 8, timing unit; 9, master control device; 10, background computer; 11, Surveillance center; 12, relay protection device; 13, counting unit.
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment mono-: several relay protection devices 12 original in power system are all connected with master control device 9, and master control device 9 is connected with background computer 10, Surveillance center 11, and master control device 9 is for controlling the operation of whole power system. As shown in Figure 1, the relay protection device real-time monitoring device of now setting up comprises the first R-T unit 1 and the second R-T unit 2, and can carry out to relay protection device 12 testing fixture 7 of self-examination. The first R-T unit 1 is connected with master control device 9, specifically comprises that the first sending module 3 and the first receiver module 4, the second R-T units 2 are arranged on relay protection device 12, specifically comprise the second sending module 5 and the second receiver module 6. The first sending module 3 is connected by self-test signal with the second receiver module 6; the second sending module 5 is connected by self-detection result signal with the first receiver module 4; wherein; the first sending module 3 is for broadcasting the module of issuing an order; its self-test signal sending is all issued an order with the form of broadcast, and the self-detection result signal that the second sending module 5 sends obtains according to the check result that is arranged on the testing fixture 7 on relay protection device 12. Meanwhile, the first R-T unit 1 is also connected with a timing unit 8, for controlling the frequency of the first R-T unit 1 transmitted signal.
As shown in Figure 2, the operation principle of this relay protection device real-time monitoring device is as follows: first, the first sending module 3 of the first R-T unit 1 sends self-test signal by the form of broadcast, conventionally control every 10 seconds and issue an order once by timing unit 8, after the second receiver module 6 of the second R-T unit 2 receives self-test signal, signal is transferred to testing fixture 7, testing fixture 7 starts relay protection device 12 to carry out self-examination, after inspection, the check result that the second sending module 5 of the second R-T unit 2 draws according to testing fixture 7 is transferred to self-detection result signal the first receiver module 4 of the first R-T unit 1 again, if self-detection result signal is normal, represent relay protection device 12 normal operations, if self-detection result signal is abnormal, represent corresponding relay protection device 12 operation exceptions, now the first R-T unit 1 again by this abnormal results signal feedback to master control device 9, master control device 9 sends the alarm signal of this relay protection device 12 " deadlock " simultaneously to background computer 10 and Surveillance center 11, the staff of Surveillance center 11 finds just can notify immediately relevant maintainer to carry out reparing hidden danger after alarm signal.
The first R-T unit can also connect a counting unit 13, when the first sending module 3 is issued an order continuously, N time (N continuous time is used for avoiding interference, the intermittently problem such as communication abnormality, by counting unit 13 to issuing an order time counting number), when the first receiver module 4 is not all received the feedback of self-detection result signal, the first R-T unit 1 also can judge this relay protection device 12 operation exceptions, simultaneously can be by this abnormal results signal feedback to master control device 9, master control device 9 sends the alarm signal of this relay protection device 12 " deadlock " simultaneously to background computer 10 and Surveillance center 11, the staff of Surveillance center 11 finds just can notify immediately relevant maintainer to carry out reparing hidden danger after alarm signal.
Because the present invention has adopted the first R-T unit 1 being connected with master control device 9, and the testing fixture 7 that is provided with the second R-T unit 2 and detects for oneself on relay protection device 12, the mode control relay protection device 12 of issuing an order by broadcast carries out oneself and detects, feed back to judge its operation conditions according to the information of relay protection device 12 again, realize the Real-Time Monitoring that relay protection device 12 moves, any operation exception all can be found in time, avoid protective relaying device to cause its incorrect operation because of long-time abnormal work, also can avoid erroneous judgement and the omission of manual patrol to equipment state, greatly promote the security performance of power system.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this. All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
