Design and Implementation of Optical Fiber Line Auto Switch Protection for Power System

Abstract:

To overcome the problem that the artificial scheduling can not deal with optical fiber switching in time when optical fiber is broken or damage in power system, we designed an optical fiber line auto switch protection system. The system used six 4x4 optical switches to compose an optical switch array that eight working fibers can share four alternate fibers. Comparing with other system, the new system more effectively utilizes alternate fibers, and is more suitable for practical power system. It used single chip microcomputer as control chip of optical switch, when the received optical power is lower than predefined threshold, the control chip will control the optical switch to alternate fiber line in time to ensure the real time and reliability of optical fiber communication. In the same time, the new system can communicate with host computer to alarm, display fault optical fiber line and remote control, and be controlled by button to realize the manual switch of optical fiber line.
