UFS campuses are transforming into research instruments while simultaneously improving campus operations through the Smart Grid initiative.

Imagine living in a smart home. Imagine monitoring your household’s electricity usage via an integrated system that would notify you of your daily electricity use, peak usage times, and tariffs and consumption at the location of the house. As a user, you would be able to take advantage of such information in order to manage your resources in a more efficient manner. This is just one example of what a Smart Grid can do.

The University of the Free State’s (UFS) Faculty of Natural and Agricultural Sciences has teamed up with the Department of University Estates to drive our very own Smart Grid initiative that is transforming the university’s power network into one with full control and monitoring. “A Smart Grid allows for resource optimisation and asset protection, especially in times like these,” said Nicolaas Esterhuysen, Director of Engineering Services. 

Why is it important for our university to have a Smart Grid?
Dr Jacques Maritz, Lecturer of Engineering Sciences at the Faculty, considers a Smart Grid the natural evolution of power grids in the era of Big Data, IoT and Machine Learning. Resources such as electricity, water and steam can now be monitored and controlled to promote savings and the protection of valuable infrastructure. “Aiming towards Smart Grid status, the UFS will improve resource service-delivery to its staff and students, while sculpting a digital twin of its campus’s power grid, consumer network and resource generators,” he added.
  
How will a Smart Grid improve student success?
The integrity, sustainability and continuous supply of energy directly affects the academic project on all three campuses. The implementation of a Smart Grid could allow improved service delivery and reaction time when any utility is interrupted, as well as maintaining the valuable infrastructure that serves the UFS community.

In what way does a Smart Grid improve the lives of staff members?
According to Dr Maritz  and Esterhuysen: “A Smart Grid will support staff to perform their teaching and research duties in a seamless manner, continuously optimising the energy that they consume to enable full comfort and reliability in energy supply, whilst simultaneously generating savings in energy and preventing wastage.”

The UFS already boasts most of the fundamental building blocks associated with the Smart Grid initiative, especially focusing on monitoring, grid protection, centralised and decentralised solar PV generation and software platforms to serve all these domains. However, to integrate all of these domains into one digital real-time paradigm will be a first for the UFS.

Some examples of the UFS smart grid applications currently in practice
Real-time remote monitoring and control that focuses on the following:
- We are able to detect power outages and don’t have to rely on customer complaints. This enables faster response time and fault identification, thus less downtime and an increase in reliability;
- Solar plant generation; 
- Monitoring our standby generation fleet; 
Identifying usage patterns and saving thereof;
Benchmarking buildings in terms of application usage, area or occupancy to determine energy efficiency and identify savings; and condition-based preventive maintenance that will increase reliability while saving costs.

A tale of many cities – new dictionary of place names reveals our heritage
2015-01-28

 

‘The Dictionary of Southern African Place Names’ provides not only the answers, but also gives insight into how our places and our people were shaped. Penned by three academics from the University of the Free State (UFS), it is the fourth edition of this fascinating book.

Prof Peter Raper from the UFS Unit for Language Facilitation and Empowerment, together with his colleagues Prof Theodorus du Plessis and Dr Lucie Möller, created more than a reference book. They provide the reader with deeper understanding of events, our heroes, beliefs, values, fears and aspirations.

Jonathan Ball Publishers describes the book as “the most comprehensive glossary of Southern African towns, villages, railway stations, mountains, rivers and beaches. The 9 000 short entries incorporate data from sources dating as far back as 1486, encapsulating the linguistic and cultural heritage of all the peoples of the subcontinent, past and present.”

And what would the origin of the name Bloemfontein be?

This dictionary provides the following answer.

“Capital city of the Free State and judicial capital of South Africa. It was established in 1846 by Major HD Warden at a fountain on the farm Bloemfontein, originally owned by a Griqua, Mauritz Pretorius. It has been claimed to have been named after a person with the surname Bloem, or in honour of the Khoikhoi chief Jan Bloem, or after an ox with this name. Probably, however, it was named after flowers growing at the fountain, from Dutch bloem, ‘flower’, fonteijn, ‘spring’. The name is thought to be a translation from a Bushman name of which Mangaung is the Sotho adaptation; ma- is the Sotho plural prefix or class marker; the component ngau is comparable to the Bushman word //au, ‘flower’, and the final ng is cognate with the locative demonstrative ?, ‘that (one) there’. Bloemfontein attained municipal status in 1880.”
