Abstract

Opisani su osnovni principi i elementi sustava za trajno praćenje i ograničenje potrošnje energije i vode u industrijskom postrojenju, dan je kratak pregled postojećih rješenja i prijedlog optimalnog rješenja u vidu SCADA sustava sa PLC uređajima. Razvijen je algoritam za kratkoročno predviđanje potrošnje te dana preporuka za izvođenje mjera za ograničenje vršne potrošnje. Predloženi sustav je realiziran u jednom većem industrijskom postrojenju. U pogonu je gotovo dvije godine i ostvarene su uštede koje višestruko premašuju vrijednost investicije. Pristup problemu je izveden na moderan način uz relativno mala ulaganja uvažavajući prilike u industrijskim postrojenjima u Hrvatskoj. Ovim radom je prikazan način, mogućnost i opravdanost ugradnje elektroničkog mjernog sustava za praćenje i ograničenje utroška energije u industrijskim postrojenjima.

Abstract (english)

Basic principles and elements of the electronic system for supervision and limiting energy and water consumption in industry plants are presented. Short overview of existing solutions is shown and optimal solution in form of SCADA system with PLC’s is suggested. Algorithm for short-term consumption prediction was developed and precautions for limitation of industrial plants energy consumption are given. Recommended system was realized in a complex chemical industrial plant. It is in use almost two years and achieved savings in energy expenses are multiple higher than initial investments. Problem approach was realized in a modern way with relatively low initial investments, regarding situation in Croatian industrial plants. This work shows how and why to implement electronic system for supervision and limiting energy consumption in industrial plants.
