Smart grid is the most ingenious and experimental technology in the present era. Assimilation of information and communication technologies with electrical infrastructure is the fundamental part of smart grid deployment. Smart grid communication architecture is a methodical framework of networks incorporating varied set of communication standards. Microgrid is the significant component of smart grid as it facilitates and expedites the usage of renewable energy assets. It can resolve the critical problems like unelectrified villages, electricity theft, depletion of fossil fuels, GHG emissions and greenhouse effect. Smart microgrid can function in two modes, namely grid-connected and island mode. It also encompasses hierarchical communication networks for automation of entire system. This paper describes the design and implementation of data acquisition and control system for smart microgrid prototype using IEEE 802.3 and IEEE 802.11 standards.

The use of an automated Data Acquisition System (DAS) is very important in testing and measurement systems. The desire is extremely high in the DAS with high speed, multi-channel, and large capacity, so research in this area becomes very significant. The growing problem in DAS is to acquire the data with the required data rate and store data onto the on-chip memory. Microcontroller, microprocessor or Digital Signal Processors (DSP) devices can be programmed as a DAS, but these devices comprise problems, such as slower data acquisition rates, nonavailability of sufficient on-chip memory, etc. To overcome these above drawbacks, this paper provides an approach to design and develop DAS based on the Field Programmable Gate Array (FPGA). To acquire the data from Analog to Digital Converter (ADC) to FPGA, an Inter Integrated Circuit (I2C) serial communication protocol is used. I2C master communication protocol is designed and developed using VHDL with the Quartus II version 13.1, and the I2C master protocol is implemented in cyclone III FPGA. FPGA is acting as a master controller. DAS with the FPGA will provide the better acquisition results compared to the existing acquisition system.

The development of data acquisition system for operation of the Kartini reactor was carried out by using a programable-logic controller (PLC) and based on the recommendation of an expert team of the International Atomic Energy Agency which justifies that the previous data acquisition system of the reactor operation has been considered obsolete. This research purpose is to follow up the recommendation by using a recent technology of PLC as the basis of the system. The parameter acquisition method was done by acquiring the analogue and digital voltage signals by the PLC and processing them into values accordingly. Analogue parameters: linear power, logarithmic power percent, period, and three control bars, Digital parameters: trigger trip signals. Parameter values are visually displayed using LabVIEW. The test method was comparing the obtained values to the current monitoring subsystem. Test results: linear power error is 0.09%; period error is 0.8%; and error of the three control rods is below 1%. All digital signal test results successfully show appropriate trip conditions when active. The conclusion of this study is successful in making a design of the Kartini Reactor process parameter acquisition system with small relative errors to the existing system.

The paper details the design of a data acquisition system for evaluating blade and shaft designs of a propulsion system for a human powered submarine. The objectives of the design were to sample and store data representing several analog signals and the time of measurement, and to display velocity and shaft rpm for the submarine operator in real-time. The sampled parameters are then used to calculate the submarine's performance in terms of velocity, thrust shaft torque and rpm. Several parameters are displayed in real-time to aid the submarine operator with training. System design restrictions including size, power requirements, heat dissipation, data integrity, and others had to be considered. Since the data acquisition system is a completely portable system, if is possible to incorporate the system into other applications. >

Design, development and testing of real time control and data acquisition system for R&D IC H&CD source

Digital application has moved towards operating speed of hundreds of Mega Hertz, with the sampling speed of ADC moving into Giga Hertz range. There is an increasing need for the design and development of a high-speed data acquisition system that is capable of capturing and processing digitized analogue signal at high speed. Due to the tight timing budget, high operating speed components, Emitter-Coupled-Logic families components with rise time of typically less than 300 ps were used in the design. With this operating speed and short rise time, signal integrity issues like reflections due to impedance mismatches and crosstalk among the traces of the printed circuit board can no longer be neglected. A quick and reliable approach was taken in the design and implementation of a 1 GHz high-speed data acquisition system using commercial-off-the-shelf discrete components. High-speed digital design issues and methodology were explored in this project and verified with the implemented hardware. This paper gives an overview of the system and focuses on the use of functional and signal- integrity computer simulation software to confirm system performance at the early design stage before actual hardware implementation. Simulation results were further confirmed with the actual hardware implemented, and was found to be close. This has helped to reduce the design cycle time and development cost of the project.
