The shipboard power system (SPS) supply energy to sophisticated systems for weapons, communications, navigation and operation. So when the system is damaged, the faults should be isolated and restored immediately to ensure the system survivability. Currently the genetic algorithm (GA) is successfully used to SPS fault restoration and the superiority over the other methods is proved, but the sim...

This paper describes the development of a real-time digital simulation platform that can be used for the teaching of design principles for power system controls. In the developed approach, a rapid controller-prototyping platform (dSPACE) is interfaced to a real-time power system simulator (RTDS). The real-time platform is very successful when used in a post-graduate University course; but shoul...

Damping devices antiresonance transformers, which are used for preventing the occurrence of ferroresonance phenomena, effective in a certain area influencing factors. The article presents methods studying possibility operation 6-220 kV based on physical mathematical modeling. results tes...

Software models for protective relays offer an economic and feasible alternative to studying the performance of protective relays. Relay models have been long used in a variety of tasks, such as designing new relaying algorithms, optimizing relay settings and training personnel [1]. In order to be practical, software relay models must reproduce the actual operation of the physical relays. This ...

Approximate pattern matching is comparing an unknown pattern with a database of stored patterns with a specified error tolerance. This ability to compensate for real world sensor errors makes approximate pattern matching an ideal choice for a wide range of applications including fingerprint, picture and bar-code identification, industrial automation, robotics and bioinformatics. This paper show...

The increasing penetration of inverter-based distributed generations (DGs) significantly affects the fault characteristics of distribution networks. Fault analysis is a keystone for suitable protection scheme design. This paper presents the modelling methodology for distribution networks with inverter-based DGs and performs fault simulation based on the model. Firstly, a single inverter-based D...

Visit analog.com There are several types of temperature sensors that can be used in a temperature system. The temperature sensor to use depends on the temperature range being measured and the accuracy required. Along with the sensor, the accuracy of the temperature system depends on the performance of the analog-to-digital converter (ADC) to which the sensor is interfaced. A high resolution ADC...

Abstract Zhangbei Flexible DC Grid project with grid characteristics is different from the previous multi-terminal flexible project. uses a breaker (DCB) to isolate line faults. Limited by current domestic research and development level of high-voltage DCB, it does not have overload operation capacity. Against this problem that DCB endangers safety equipment system after permanent fault overhea...

—Since Distributed Generation (DG) often involves renewable energy, it is important to facilitate integration of DG into existing networks. This is the aim of the EU FP6 demonstration project ADINE. It is based on the Active Network Management (ANM) concept, where automation, ICT and power electronics are used to integrate more DG by exploiting active resources instead of just reinforcing the n...
