Applying IEC61499 for Building Management System

Abstract

In nowadays, the term "Intelligent Building Management System" is getting more and more popular and it has generated a good deal of excitement during the last decade, much of which subsequently dissipated once the limits and complexities of building intelligence were discovered. NxtControl [1] reports on a number of commissioned building management systems (BMSs) where distributed control and visualization of the entire building was implemented using IEC61499. The IEC 61499 standard describes a software element called a Function Block (FB) which aims to provide object-oriented features to the design of industrial systems. This thesis presents a distributed BMS developed in a commercial IEC 61499 solutions called nxtStudio, the distributed BMS involved developing three subsystems: light & air subsystem, boiler subsystem and elevator subsystem; FB implementation of these subsystems are discussed. DALI concept of Lighting System is also addressed in the research: Integration of DALI Light system into a BMS and FB Implementation of DALI Light system in nxtStudio. BMS always been discussed in Demand Side Management (DSM) because it responsible for a large part of the power consumed in the industrialized world. Smart meters are always used in DSM because smart meters are cheap, capable to generate large amounts of information through bi-directional communication between consumers and the utilities. This paper proposed a Smart Metering System of Lighting System based on IEC61499 which enables the integration of other technologies such as demand response. Real-time consumption level data can be transferred to the utilities, and will enable the consumers to monitor their electricity consumption and take measures to reduce their usage. This proposed Smart Meter System not only focuses on cutting a part of consumers' load, but also cutting a percentage of the load of every consumer in order to maintain a minimum level of comfort. And the approach further advances Smart Meter System design towards a goal of DSM tool in IEC61499.
