Method of Signal Proceeding of Adaptive Optical Current Transducer
Abstract:To realize the Adaptive Optical Transducing Principle and Square Root Kalman Adaptive Filter, the method of signal proceeding baesd on DSP is introduced in this paper. the signal proceeding system of AOCT is formed, which possess adaptability and expansibility of signal output. The AOCT and its signal proceeding system have been installed in 35kV transmission lines. The operation results indicate that they take on the excellent measurement performance under the steady state and transient state, and insure the reliability of transmission line differential relay and other protection.
