| Abstract: | Based on substation feeder monitoring unit the latest AC sampling algorithm with improved accuracy was adopted in the new generation of 80C196KB microprocessor. The utilizing of two CANBUS redundancy structure to communication with its host resulted in better reliability. Lattice liquid crystal display with filmy keyboard and menu display technique were used to fulfill man machine interface. Besides the traditional functions of telemetry, tele indication, tele control and tele pulse, two level isolation technique and various software anti jamming techniques were introduced to improve the quality of digital and pulse signal sampling as well as tele control. |
