Adaptive Relay Protection Concept for Smart Grids
Smart Grid refers to an intelligent grid that employs modern information and telecommunication technologies to meet the challenges relating to the power delivery in the future. These challenges are due to, among others, increased use of renewable energy and power supply reliability requirements of modern digital society. In order to fully realise the Smart Grids a new kind of approach for the p...
متن کاملOptimal Combined and Adaptive Protection of Active Distribution Networks Considering Different System Topologies Incorporating Optimal Selection of Standard Relay Curves
The change in the topology of active distribution networks (ADNs) is one of the essential challenges that might affect the protection schemes. The conventional protection schemes based on base topology result in some coordination constraint violations in other topologies due to the outage of upstream substations and distributed generation units. In this article, new combinational and adaptive p...
متن کاملStaged-Fault Testing of Distance Protection Relay Settings
In order to analyze the operation of the protection system during induced fault testing in the Croatian power system, a simulation using the CAPE software has been performed. The CAPE software (Computer-Aided Protection Engineering) is expert software intended primarily for relay protection engineers, which calculates current and voltage values during faults in the power system, so that relay p...
متن کاملDistance protection closed-loop testing using RTDS
This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
متن کاملOn the Effectiveness of Genetic Operators in Adaptive Random Testing
Adaptive random testing (ART) has recently been found to be an effective way to improve the performance of random testing by selecting widespread test cases from the input domain. In this paper, we outline how the selection, mutation and crossover operators of the genetic algorithm (GA) can be used in ART, and investigate experimentally which of these is the most appropriate operation to serve ...
