ELECTRIC SUPPLY AUTOMATIC SYSTEM OF WAVELENGTH DIVISON MULTIPLEXING BASES FOR AN ELECTRIC SUPPLY PROTECTION COOPERATIVE INFORMATION TRANSFER

摘要

PURPOSE: An automatic distribution system based on WDM for transferring power distribution protection coordination information applying the power supply network of a close loop mode is provided to individually transmit protective coordination information between terminals. CONSTITUTION: An FRTU(Feeder Remote Terminal Unit)(220) converts a control signal and protection cooperative signal information in a form of RS-232. The FRTU performs a protection coordination algorithm. An optical modem(230) converts the control signal into the first optical signal. A high speed data transmission unit(210) converts the protection coordination signaling information into the second optical signal. The high speed data transmission unit multiplexes the first optical signal and the second optical signal. The high speed data transmission unit transmits the multiplexed optical signal through one optical cable.
