ECEN 405 Students See Power Electronics in Action at Haywards Substation
On the 16th
of June, students enrolled in ECEN 405 visited Haywards Substation in Stokes Valley, in order to see power electronics at work on a large scale. They were accompanied by the course lecturer Dr Ramesh Rayudu, technicians Jason Edwards, Tim Exley and Sean Anderson, and two post-graduate students, Dayna-Maree Kivell and Matt Bourne.
Hosted by 5 staff from Transpower, the students were shown pole 1, which contains the ‘old-style’ mercury-arc valves that have been in operation since the 1960’s. The students also toured Pole 2 where they had a closer look at the thyristors used for power conversion. Transpower staff also toured the students through Pole 3 that is currently under construction, and explained the processes involved. More particularly the students got up-close look at capacitors, filters and synchronous condensors at work.
The students appreciated the enthusiasm of the Transpower staff for their field of expertise, and their willingness to provide detailed explanations of how things work. “The fact that what they said made sense after doing power electronics totally made the course worthwhile” said Henry Williams.
The trip also gave students an ideal opportunity to see how the things they had learned about in class were applied in real life. “The sheer size of the equipment used was astounding, but at the same time, the knowledge gained from the ECEN course allowed us to understand the theory behind it all.” said Luke Frogley.
The students thanked Dr Rayudu for organising the trip, and sharing the practical knowledge he has acquired from working in the industry. Dr Rayudu says Transpower staff enjoyed hosting the students, and hopes that a visit to Haywards substation will become a regular component of the course.
