Simultaneous power sharing and protection against faults for DGs in microgrid with different loads
The LVRT (Low Voltage Ride Through) is the main characteristic of every power system in faulty conditions. When fault occurs, it is essential for power system such as microgrid to control the voltage and frequency normally. Naturally in fault status, the unbalanced voltage and current are inevitable, but with the aid of LVRT technique, microgrid can keep stability in main system parameters such...
متن کاملMultiple Power Supply Pad VDDT Testing for Delay Faults
In today's competitive IC market, success often means delivering the shortest possible clock cycle. Under pressure to push increasingly complex processing technologies to the limits, designers are delivering circuits with decreased timing and noise margins. In doing so, they are making the circuits significantly more susceptible to manufacturing imperfections. In particular, previously benign m...
متن کاملA fuzzy logic based relay for power transformer protection
rotection schemes employing the differential relaying principle exhibit certain limitations in applications with power transformers. This is because the detection of a differential current does not clearly distinquish between internal faults and other possible conditions. Among the phenomena most likely to upset the current balance and cause the relay to malfunction are inrush magnetizing curre...
متن کاملDynamic Relay Selection Method for Distributed MIMO Relay System
The research on distributed MIMO relay system has been attracting much attention. In this paper, a decode-and-forward scheme distributed MIMO relay system is examined. For upper bound of channel capacity, the distance between transceivers is optimized when the propagation loss is brought close to actuality. Additionally, the number of relay is optimized whether total antenna element is fixed or...
متن کاملDetecting delay faults using power supply transient signal analysis
A delay-fault testing strategy based on the analysis of power supply transient signals is presented. The method is an extension to a Go/No-Go device testing method called Transient Signal Analysis (TSA) [1]. TSA detects defects through the analysis of a set of power supply transient waveforms in the time or frequency domain, e.g., Fourier phase components. A recent extension to TSA demonstrated...
