Description
Technical field
The invention belongs to power system automation technology field, relate to the repair method that a kind of relay controls class device.
Background technology
In intelligent substation, relay protection controlling device can pass through inspecting state; maintenance position (test) in quality (Quality) in SV and GOOSE message is arranged; FALSE is non-inspecting state (no-test), TRUE is inspecting state (test).Device internal receipt merge cells or intelligent terminal send data, judge whether merge cells or intelligent terminal are in inspecting state accordingly.In like manner turnaround of unit state, also visible in the data being issued to intelligent terminal.
Relay protection controlling device is because electric secondary circuit directly and device terminals or shield cabinet terminal and connect each other, must disconnect electrical connection in plant maintenance.Because associated loop is complicated, the output clamping quantity that needs throwing is moved back is a lot, and safety measure is loaded down with trivial details, easily makes mistakes, or omits cutoff circuit, or omits recovery loop, and hidden danger is more, often causes human accident.
Summary of the invention
The present invention is in order to solve the above-mentioned defect and deficiency that exist in prior art, and provide the repair method that a kind of relay controls class device, achieve the service without power-off to device, the method is simple to operation.
For solving the problems of the technologies described above, the invention provides a kind of repair method of relay protection and control class device, comprising the following steps:
Step one, drops into maintenance pressing plate, arranges maintenance pressing plate or open into, control word to device, when open into or control word effectively make, device is in inspecting state, and device is in inspecting state by cue prompting operation maintenance personnel device;
Step 2, the automatic safe isolation of device, application of installation and external circuit are passed through to be electrically connected, the off-the-line of implement device and external circuit;
Step 3, select isolated subject maintenance debugging, device provides debugging interface, and device is connected with tester by described debugging interface, the monomer test of implement device, and whether the function of demo plant soft and hardware is correctly complete;
Step 4, maintenance debugging terminates, and exits maintenance pressing plate.
Wherein, in described step one, device cue will be delivered to automated surveillance system.
In described step 2, the mode of device automatic safe isolation is OO layering and zoning set-up mode.
Described step 3, is comprised device and is connected with tester by debugging interface, receives and meets the SV sampled data of IEC61850-9-2 standard and the GOOSE data of IEC 61850-8-1 standard, realize the mutual of test data.
Aforementioned cue comprises signal lamp, interface display, message information.
Aforementioned layering and zoning set-up mode is specially, if isolation mode analog quantity loop feature, then the IO of holding device and peripheral operation loop and signal circuit contact, and continue to use traditional disconnection output clamping circuit, check the maintenance model in outside DO loop one by one; If isolation IO loop feature, then holding device sampling contacts with outside transformer secondary circuit, continues to use the quarantine measures of traditional sampling circuit, by disconnecting the mode of secondary voltage switch and short circuit secondary current terminal.
The Advantageous Effects that the present invention reaches:
During inspecting state, device light signal lamp and on send state message information to automated surveillance system, prompting operations staff device is in inspecting state.Application of installation and external electrical contact off-the-line, off-the-line mode object-oriented, and layering sub-module realizes loop off-the-line, can realize the maintenance debugging of analog input and IO input and output respectively, can compatible original traditional maintenance model.Device provides Special debugging interface, can by external tester to device input debug signal or order, for demo plant logic and module operating mode, so can realize when any variation is not done in loop safeguarding device, safety measure is easy, recovers nominal situation and also only maintenance pressing plate or control word is exited.Device, by the one-touch Secure isolation of maintenance pressing plate, simplifies safety measure, realizes operation maintenance debugging efforts, and can carry out repeatedly debugging efforts by flow process like this, and safety measure recovers reliably easy, and inspecting state instruction is clear.
