DATA COLLECTION AND COMMUNICATION PROTOCOL OF FEEDER TERMINAL UNIT IN DISTRIBUTION AUTOMATION

On the basis of engineering practice, the amount of information which should be collected by remote feeder terminal unit is analyzed and discussed. According to the basic demand on the distribution automation and the features of the amount of information collected by FTU, some special problems of applying the standard protocol IEC 60870—5—101 (DL/T634—1997 in National Standard of China) to integrated automation of distribution network are also discussed in this paper.
