A new measuring architecture for phase-based infrared ranging applied to indoor positioning is presented. The motivation to develop this proposal was to reduce the critical effect of multipath interferences on the differential distances estimated by the ranging system. The multipath mitigation feature of the proposed system is based on applying a spread spectrum modulation on the emitted signal so...
This paper describes an Embedded System (ES) for an inverter. In recent years, there is a worldwide interest in Distributed Generation (DG). This is due to the need to integrate renewable energy sources into the Distribution System. This paper proposes the development of a platform to the safe and intelligent management of the DG in the grid. The proposed system requires a platform to integrate, among...
This paper presents an universally deployable controller geared toward emerging Smart Grid inverter communication/control standards. The Smart Grid Inverter Interface handles communications, security, signal I/O, and processing of information for grid interoperable power converters. This paper proposes the development of a platform to the safe and intelligent management of the DG in the grid. Our...
The term Smart Grid refers to a completely modernized electricity delivery system which monitors, protects and optimizes the operation of its interconnected elements from end to end. The Smart Grid is expected to affect all areas of the Electric Power System, generation, transmission, distribution and end consumers and citizens and their electric vehicles, street lighting services, and other household...
We propose a new synchronized technique for Smart Grid. A PTP-Based IEEE 1588-2008 Global System has been defined. Specifically for PMUs with synchronism needs up to the microsecond range, for Energy Measurements System (EMS), for Intelligent Electronics Devices (IEDs) and for automated real-time control systems called Special Integrity Protection Schemes (SIPS). This new Electronic Devices comprise...
Utility power quality problems like input voltage unbalance and sag conditions severely stress electronic equipment. Voltage sag forecasting is a complex issue, since it involves a large variety of random factors, such as: type of shortcircuits in the power system, location of faults, protective system performance and atmospheric discharges. Recently, the AC-AC converters have been proposed as voltage...
Voltage dips analysis is a complex stochastic issue, since it involves a large variety of random factors, such as: type of short circuits in the power system, location of faults, protective system performance and atmospheric discharges. Among all categories of electrical disturbances, the voltage dips (sags) and momentary interruptions are the nemeses of the automated industrial process. On the other...
