Distribution Protection Relay Software Models in Interaction with Power System Simulators
نویسنده
چکیده
Modelling and simulation software developed for analysing protective relaying applications and relay (IED) design concepts in power distribution is described in the paper. Matlab has been selected as programming environment for protective relaying software modelling. Within Matalabs Simulink environment, SimPowerSystems is selected as a design tool for modelling and simulating a distribution power system. The system is modelled according to the two real radial distribution networks in which field (short-circuit) tests were conducted. Current and voltage measured records from tests are used for model verification and also as a signal source for testing the relay models.

متن کاملProviding a protection method to support distributed generation against transient voltage instability
The analysis of transient stability in electric power systems and the penetration coefficient of scattered productions play important roles in the regulation of protective equipment, so these parameters should be considered two main factors in the electrical protection of power networks. Overcurrent relays are used as one of the simplest and most effective solutions for power system protection....
متن کاملAnalysis of Protective Relaying Operation and Related Power System Interaction
Advanced techniques for analysing operation of protective relays and related interactions with the power system are discussed. Three major issues are addressed: evaluation of existing physical relays, study of new and/or existing relays using relay models, and assessment of relay operation and its interaction with the power system using models of both relays and power system. The underlying app...
