Description
Technical field
The utility model relates to relay protection of power system equipment, especially relates to a kind of relay protection channel monitoring wave recording device.
Background technology
Along with OPGW(Optical Fiber composite overhead Ground Wire) widely using on transmission line, increasing transformer station has possessed optical-fibre channel.And optical-fibre channel safe and reliable with it, safeguard that simple, stable, antijamming capability is strong, passage possesses the clear superiority such as self-checking function at any time; particularly optical fiber differential protective criterion simple, be swift in motion; substantially increase the reliability of main protection; for this reason, the main protection passage of 220kV and above relay protection of transmission line device is just progressively from being main transfer use optical-fibre channel to hf channel.Because factory's intersite line need be exchanged and unit throws information such as stopping state, operate power, protection act between regional safety stabilization control device, also mostly use optical-fibre channel as the carrier of information interaction.
But, although optical-fibre channel relative high frequency passage is more safe and reliable, safeguard also simpler, but in running, still can there is channel alarm because of a variety of causes, some hidden failures are particularly there are, interrupt time normal during passage, after maintainer reaches the spot, passage may recover normal, do each side inspection all normal, cannot the localization of faults, and protection resume operation occur soon interrupt, harmful effect is caused to the safe operation of relaying protection and electric power system, especially area stability control device often forms a holonomic system (being generally two cover redundant configuration) by the stability control device of 500kV transformer station multiple in region and 220kV transformer station, a channel abnormal of certain a set of stability control device of a transformer station, often need to exit whole devices that this cover is surely controlled, operating process is complicated, affect wide, likely cause the generation of region limited load situation.Therefore, occur extremely in optical-fibre channel, fault point should be found as early as possible, recover passage and the normal operation of be correlated with protection, stability control device.
The test of relaying protection optical fiber designated lane, generally takes to test sending and receiving luminous power to check the whether enough methods with taking from ring test of nargin.The test of numeral 2M multiplex channel, generally takes the test error rate or the method from ring test.These method of testings all must destroy the original operating state of passage, and can not monitor and catch, preserve the data transmitted in passage, therefore cannot carry out detailed analysis, and be not particularly the soft fault of sustainable existence to some, the location of fault is more difficult.
If there is one can carry out intervention test to relaying protection dedicated optic fiber channel, digital multiplexing 2M passage; to go forward side by side the novel test device of line item keeping relaying protection or the safety stabilizing devices message under operation in capture channel; according to passage message analysis channel abnormal during fault be because of CPU transmission message exception or passage attenuation is excessive or other reasons causes; thus fault point is positioned, very helpful to fixing a breakdown in time.
Summary of the invention
The purpose of this utility model is to provide a kind of relay protection channel to monitor wave recording device; it can carry out record to the channel data of protective relaying device (multiplex channel of the dedicated optic fiber channel of circuit optical fiber differential protection, multiplex channel, stability control device); by to acquisition data analysis; channel failure point is positioned; to fix a breakdown in time, recover relevant protection device and run.
The purpose of this utility model is achieved in that
A kind of relay protection channel monitoring wave recording device, comprise housing, feature is: on the front panel 2 of housing, be provided with LCDs, working station indicator, power supply indicator, channel alarm indicator light and operation keyboard, in housing, circuit board is installed, is provided with a central processing circuit, power circuit, several identical channel signal treatment circuits, several identical optical splitters on circuit boards; Each channel signal treatment circuit comprises a 2M passage input interface, a RS232 compunlcation interface, the channel signal of each channel signal treatment circuit exports the channel signal input of termination central processing circuit, and each optical splitter comprises an optical channel input interface, optical channel output interface, a monitoring light output interface; Interface when central processing circuit is provided with Ethernet compunlcation interface and GPS couple, central processing circuit carries out communicating and managing with each channel signal treatment circuit, the compunlcation interface of central processing circuit communicates with backstage computer, so that backstage computer can carry out analyzing and processing from central processing circuit Acquisition channel data, when during GPS couple, interface is used for accurate pair.
Power circuit comprises three kinds of specifications, a kind of inputs, for connecing transformer substation communication power supply for direct current 48V; The second is that direct current 220V inputs, for connecing the power supply of transformer station's main storage battery; The third is alternating current 220V input, for connecing electric main.The utility model only need configure any one power circuit and get final product work, also configurable wherein two kinds, more flexible to make power supply input.
2M passage input interface in channel signal treatment circuit is used for the input of monitored 2M passage, and RS232 compunlcation interface is used for backstage compunlcation to analyze, store data.
Each optical splitter light splitting ratio is 3/7, when monitoring optical-fibre channel, obtaining light signal, accessing 2M channel signal treatment circuit monitor by the special photoelectric conversion equipment of external corresponding producer after being converted to 2M channel signal for sealing in optical channel.
Operation principle: channel signal treatment circuit is by access 2M passage, the communication protocol of the channel data of acquisition by setting is analyzed, channel data and the relevant alarm parsed, error message are sent out central processing circuit, stored by central processing circuit, and send to display to show.
Therefore, the utility model can be monitored the communication data in optical-fibre channel, 2M passage and be stored it, or outputs to backstage computer for analysis, storage by communication interface.The utility model can be monitored multiple different passage simultaneously.
