Komprehensibong Solusyon sa Smart Meter Batas sa Advanced Metering Infrastructure (AMI) ug Application Prospects
I. Buod ng Solusyon: Konsepto ug Pagpalambo sa Mga Smart Meters
Ang konsepto sa mga smart meters wala gyud kini usa ka bag-ong butang; nagsugyot kini sa higayon nga 1990s. Sa dili pa, gipagbatasan kini sa mataas nga gasto (sa 1993, ang ilang presyo mao ang 10–20 ka beses sa electromechanical meters), ug gamiton sa pag-usab sa dako nga industriya ug komersyal nga mga customer.
Sa rapid nga pagpadayon sa teknolohiya sa komunikasyon, ang numero sa mga smart meters nga may remote communication capabilities nahimong daghan, ug nagresulta og urgent nga panginahanglan alang sa bag-ong sistema sa meter reading ug data management. Ang mga unang sistema makapila ang metering data sa mga sistema sama sa distribution automation apan wala makamit ang effective ug in-depth utilization sa data. Samtang ang real-time nga energy consumption data nga gilumdon sa prepayment meters wala makamit ang full potential alang sa energy management ug energy-saving applications. Kini nga solusyon naghangyo sa pagbuhat og Advanced Metering Infrastructure (AMI) nga sentral sa mga smart meters aron mas mapatuman kini nga mga isyu ug bukasan ang dako nga potential sa data.
