Improving the learning experience of power system protection students using computer-based simulations and practical experiments

Abstract

Abstract-This paper presents a survey on the activities carried out to improve the learning experience of electrical engineering undergraduate students in power system protection unit in Curtin University, Australia. The unit was conducted initially based on lectures and tutorials where only two sessions on computer simulation and one session of laboratory demonstration were conducted. In academic year of 2013, to improve the learning experience of students, several computer-based simulations and laboratory experiments were prepared. The students are introduced with two power system analysis software, namely ETAP and PSCAD/EMTDC which are used to demonstrate the overcurrent relays performance and their coordination as well as the time transient analysis of different faults in an electric network where some protection relays are applied. A practical setup composed of LabVolt electrical modules and SEL relays is used to simulate an electric network. Several tests are built up to simulate fault and protection layout for transformer and induction motor. Finally, a secondary injection test set is used to introduce the concepts of relay testing and commissioning.

The test bench for simulation impact of core saturation on the current transformer on coordination of inverse relay protection

“…Some research results implement a protection system platform between digital and physical directly on some specific devices [11][12][13][14][15], specifically implementation on distributed generation [11] and on protection relay experiments [12][13][14][15]. A study for protection system study to obtain the optimal operation scheme in distributed generation is proposed in Sisworahardjo et al [12], where the physical-distributed generation is integrated into the device, while two independent distribution systems are simulated in a digital real-time simulator.…”

To enhance the learning process using protection relays, a proposal and implementation to test the operation of characteristic relays [12,13]. Although industrial relays are used in this laboratory, the simulator is capable of displaying pre-fault and post-fault fault signals.…”

Effectiveness of Learning Electric Power System Transmission using Higher Other Thinking Skill based Simulation

“…Simulation tools have been applied in learning at universities such as the Electrical Transient Program at Curtin University. Simulations are used in project-based Electric Power System Protection learning, in the field of electric power system studies (Shahnia et al, 2014). In line with the research conducted by Gashimov, he has carried out simulation trials for controlled shunt reactor modeling for experimental loss measurement and dynamic operating performance of the system using a computer program (Gashimov et al, 2015).…”
