The Virtual reality electrical substation field trip: Exploring student perceptions and cognitive learning

<p style="text-indent:20px;">COVID19 has disrupted many higher education's learning experiences, including those related to work integrated learning. This included the cancelling of the annual electrical engineering field trip to a local electrical substation. Field trips provides students an opportunity to connect their classroom learning with industry relevant engaging experiences. While virtual reality (VR) alternatives to electrical substations have been implemented and researched, the focus has been on the innovation and not on the educational benefits. The impact on learning is not well documented and understood. To address this gap an experimental study is conducted on fifty electrical engineering students at the University of Wollongong to determine if a VR replica of an electrical substation can provide an equal or better learning and student experience compared to traditional methods. A successful finding would provide confidence to implement such alternatives for situations that include: addressing COVID disruptions; for students that miss the field trip; and for providers that don't have the funds or resources to visit a substation. It was found that the VR substation simulation provided a comparable student experience and stronger cognitive learning benefits than traditional methods. Further research is needed to explore learning impact beyond the cognitive domain.

Design and Application of Electronic Analog Relay Protection Device with Load Check

This paper designs an electronic substation simulation relay protection device with load check. At the same time, the device is studied and applied in the new substation. First of all, this paper analyzes the primary wiring mode and three-phase symmetrical current and voltage in the primary side of a typical substation, and confirms the transformer ratio, polarity and wiring mode of the current/voltage transformer. Then, by checking the polarity of line protection, metering, bus protection, main variable differential protection and backup protection, the polarity error of metering circuit with load check protection and metering circuit is effectively avoided. Finally, through the field test verification in the new 220kV Fuxing station of Jinzhou power supply company, it is verified that the technology adopted in this paper can fully meet the requirements of substation simulation load test. The relay-protection device with load check designed in this paper solves the problem that the conventional electric-type single-phase large-current generator can only detect the transformer ratio and polarity of the relative single-phase loop current transformer, and the difference loop cannot be detected. It shortened the switching operation time of changing ratio, polarity and phase check of the primary and secondary circuits after passing the load of the substation transmission belt.

The influence of IEC 61850 standard: implementation and development of a functional substation automation simulator

ABSTRACTThe IEC 61850 standard ‘Communication Networks and Systems for Power Utility Automation’ has resulted the integration and inter-operability of digital protective relays in a Substation Automation Systems (SAS). Under digital protective relays, Intelligent Electronic Devices (IEDs) are microprocessor-based devices used to perform numerous functions including protection, control and similar functions in a substation environment. The communication protocol that IEC 61850 can offer through IEDs is the Generic Object-Oriented Substation Event (GOOSE) protocol, which makes the peer to peer communication of different IEDs readily accessible. The development of portable simulators based on IEC 61850 is a benchmark for electrical engineering graduates, power engineers and protection engineers to be acquainted with a substation automation environment. This prompted Victoria University to build and develop portable IEC 61850 simulators which gained distinction among electrical utilities and developed into a real-world electrical substation called the Victoria University Zone Substation (VUZS) Simulator. This paper provides an overview of the growth and improvement of the different portable simulators that were initiated to satisfy IEC 61850 in the VUZS Simulator.

A Systematic Approach to Safe and Effective Earthing System Design for High Voltage Substation

In high voltage substation, earthing system is an essential part not only for providing the protection to people who are working or walking in the vicinity of earthed facilities and equipment against the danger of electric shock, but also for maintaining the proper function of the entire electrical system.
