Owing to the semantic ambiguities, it has hindered the promotion of IEC 61499 in the field of industrial automation. In order to solve the thorny problem, this paper proposes an implementation scheme for performing formal modeling and simulation verification of semantics of functional block networks. Based on the synchrony hypothesis, the formal execution model is defined according to the fixed point...
Cooling systems consume around 40% of modern data centres' total energy consumption, thus reducing the energy waste in this sector will have positive environmental impact. There exist several cooling methods appropriate for particular conditions. Since environmental conditions, such as air temperature, change on seasonal bases, no single cooling method can be claimed to be the best. In contrast, data...
A tracking simulator is an online simulation system that achieves a permanent state synchronization with the targeted process by dynamically calibrating the model state after comparing process measurements with model results. Tracking simulators are a powerful industrial application that can be utilized as a plant-wide virtual sensor for process monitoring and diagnosis as well as a predictive tool...
The so called Smart Grid is said to be enabled with bi-direction communication networks and energy flow. IEC 61850 is a substation communication standard which improves interoperability of the substation design. IEC 61499 is an automation standard which can be used for implementation of control in IEC 61850 models. This work is utilizing Model Driven Engineering techniques for substation automation...
Engineering and computer science have come up with a variety of techniques to increase the confidence in systems, increase reliability, facilitate certification, improve reuse and maintainability, improve interoperability and portability. Among them are various techniques based on formal models to enhance testing, validation and verification. In this paper, we are concentrating on formal verification...
The future distribution grid known as the smart grid will become more distributed in both infrastructure and control. IEC 61850 and IEC 61499 are two industrial standards addressing the challenges presented by a decentralized infrastructure. This paper contributes to system engineering of smart grid automation by enabling automatic generation of IEC 61499 control systems from IEC 61850 specifications...
Cooling is an extremely important process in modern data centers. Cooling systems of server rooms ensure appropriate operation conditions to IT systems, such as servers and data storage, but, on the other side, they consume a lot of energy. Current control systems, which are installed in data centers and are responsible for thermal management of the facilities, are following conservative control strategies...
This paper presents implementation of the Distributed Grid Intelligence (DGI) applications such as Intelligent Fault Management and Load Balancing using IEC61499 reference architecture. This enables system level design of distributed applications with a direct pathway to deployment to hardware. The use of IEC 61499 improves scalability, re-configurability and maintainability of automation software...
This paper presents an investigation into the migration from standard centralized control to modular, distributed control for a fruit packing machine. Along with control that was developed using IEC 61499, a simulation model of the plant was developed in parallel. Both were deployed to hardware to demonstrate seamless testing using a single underlying architecture. A visualization of the simulation...
