ABSTRACT
Recently, the monitoring service for important users in the distribution network is relatively insufficient in China, which greatly influences the efficiency of power distribution. According to the requirement of optimizing operation control in modern distribution network, a Two Way Automatic Communication System (TWACS) for the transmission of monitoring data is designed in this paper. The vital issues pertaining to distribution automation in the light of the TWACS communication technology are presented and discussed. In accordance with transmission demand and channel characteristics of modern distribution network, it adopts double zero-crossing points modulation method to improve downlink communication speed, which combines Gaussian window function and matched filtering way to restrain high-frequency interference. Meanwhile, distributed uplink receiving methods and orthogonal vector reuse are used to identify the topology structure of modern distribution network which provides the basis for power flow analysis in modern distribution network. Finally, the example analyzing how to carry on topology structure of the distribution network by TWACS shows the effectiveness of this algorithm.
