Design & Development of a Computer Network via Low Voltage Distribution Power Line Cables & PSTN for AMR of Residential Buildings

Cost reduction, easier access to data, availability of consumersʹ load profile, issuing bills and applying power usage management policies are among the main goals of electrical power distribution utilities. In the line of these duties. Automatic Remote Meter Reading has a key roll. Obviously methods for gathering data, communication media and reading style are important. In this article we are going to introduce a hierarchical solution for residential complexes that is designed for and implemented in the pilot site (Atisaz residential complex towers 15,16 and 17) in cooperation with Tehran North-West power Distribution Center. For purpose of cost reduction, the highest node (main load profile collector ) which is further away from distributed local nodes is connected to middle load profile via public switching telephone network. On the other hand middle load profile collector is connected to primary meter readers via broad-band or narrow-band power line communication network.
