Description
Technical field
The present invention relates to a kind of relay protection signal Transmission systems and method based on OLP and 2M optical interface.
Background technique
Currently, the scale of electric system is increasing with the development of economy, structure becomes increasingly complex.Operation must require
Securely and reliably, power quality height, good economy performance.However due to natural conditions, equipment and the influence for thinking factor, in fact it could happen that each
Kind failure and irregular operating state.It is most common in failure, harm it is maximum be various types short circuit.Failure or abnormal fortune
If the correct processing not in time of row state, may all cause accident.For timely correct handling failure and irregular operating state, keep away
Exempt from accident, just produces relay protection.Relay protection mainly utilizes element in electric system that short circuit or abnormal feelings occur
The variation of electrical quantity (electric current, voltage, power, frequency etc.) when condition constitutes the principle of relay protection movement.Protective relaying device
It is the core for completing relay protection function.
Need to carry out the communication of 2M optical port between protective relaying device.Traditional telecommunication transmission equipment can not be provided directly,
The conversion of line coding mode must be accompanied by while photoelectricity/electro-optic conversion in the transmitting-receiving external photoelectric converter in both ends.
New 2M optical interface scheme can be directly attached with 2M optical port between relay protection device and telecommunication transmission equipment, be reduced
