This paper proposes a design pattern based on the service-oriented architecture for the design of flexible distributed automation control system for substation automation systems. The design pattern is intended to be applied to control systems based on the leading standards for software development of smart grid: IEC 61850 and IEC 61499. The proposed design pattern models system requirements as orchestrators...
The paper aims at demonstrating the feasibility of an execution platform that is capable of performing protection and control functions from various vendors in a controlled manner. This will reduce vendor dependency enabling utilities to standardize hardware while implementing complex protection schemes from multiple vendors at reduced cost. The paper develops protection system including earth, differential...
This paper presents the design and implementation of a high-throughput Sorted QR Decomposition (SQRD) circuit for MIMO communication systems. The proposed design is architected based on a novel pipelined Givens Rotation structure comprising of multi-dimension CORDIC elements. Furthermore, this circuit reduces the excessive delays of norm-calculations and sorting operations, and thus the time efficiency...
Network functions virtualization (NFV) is an emerging network technology. Instead of deploying hardware equipments for each network functions, virtualized network functions in NFV are realized through virtual machines (VMs) running various software on top of industry standard high volume servers or cloud computing infrastructure. NFV decreases hardware equipment costs and energy consumption, improves...
A low-complexity depth-reliability-based stereo-matching algorithm and an efficient scanline memory-merging implementation scheme are proposed in this paper. The developed algorithm analyzes the accuracy of disparity results by using simple local window-based methods and preserves reliable information only. A bidirectional depth propagation flow is then adopted to fill the unreliable segments by using...
This paper proposes new type of software components for distributed automation systems that are capable of adapting to the computational load conditions by migrating to other devices. The migration is seen as a basic mechanism of bio-inspired heuristic search for more optimal overall load across distributed network of devices. The adaptable components can form digital ecologies self-configuring themselves...
This paper presents a practical framework to bring the cyber-physical block diagram models, such as Ptolemy, to the practice of industrial automation. Cyber-Physical Component (CPC) architecture is suggested. CPC aims at the improvement of design, verification and validation practices in automation of Smart Grid. IEC 61499 standard is used as a basis for this architecture. This architecture addresses...
Generating reference signal is indispensable and challenging in ferroelectric random access memory using one-transistor and one-capacitor architecture. This work presents an architecture with random-dynamic reference scheme for high speed and high reliability application. The detailed scheme and operating principle are illustrated. By rewriting memory cells and reference cells simultaneously after...
In this paper we present a prototypical smart metering infrastructure (MI) as part of the “distributed nervous system of SmartGrid”. Proposed MI is enabled with distributed programming infrastructure of the international standards IEC 61499, communication and design infrastructure of IEC 61850. The paper introduces IEC 61850 logical device for the smart meter. Based on this definition, the intelligent...
Performance Index is the foundational and essential indices of measurement of SoS(System of Systems) capability. We propose ten sorts of mapping relationships description between kernel elements of SoS architecture based on the DSM/DMM model. The formalization of model transformation, combination and transposing operators are described as the foundation of proposition of formulation to measure the...
To meet the increasing demand for mobile broadband, multiple carrier features were subsequently introduced into UMTS Release-8 to Release-10. As a consequence, the UE capabilities of rejecting inter-stream interference have increased considerably. To fully utilize the UE capabilities and wireless resources, multi-point transmissions raised concerns in 3GPP High Speed Downlink Packet Access (HSDPA)...
In this rapid development of advanced computer technology era, the trend for interaction with the input devices has shifted toward the incorporation of intelligent technology gradually. To facilitate the intuitive paradigm for human to use digital equipment, the traditional input devices such as keyboards and mice are augmented or even replaced by various novel mechanisms. The provision of the intuitive...
