Överföring av och beräkning med timmätta värden – från MT2000 till Xpower

Abstract

New technology makes it possible to remotely measure all consumers in a power network on an hourly basis and store the values in a database. This thesis work describes the conversion process between automatic meter reading system MActor and calculation software Xpower. Then the possible differences between calculations of power networks using load curves in combination with a yearly estimate of consumption and calculations using hourly measured values is examined. The result of the comparison shows that, for the power network under inspection, no significant difference could be noticed. This does not mean that calculations using hourly measured values would be unnecessary. I believe that in a near future calculations using hour measurements will be the primary choice for many power companies to whom technology is available. Also some basic calculations of fundamental power network parameters, such as power factor and loses, are presented using hourly measured distribution transformers in combinations with its hourly measured loads.
