Making the grade: How well designed is your substation and its protection systems

How well designed is your substation and its protection systems

Today is just another day at your local HV substation. Inside, the transformers gently hum and switchgear sit idle. Outside, a neighbour’s neglected tree loses a branch, which clashes with an overhead line. Ask yourself: What happens next? That depends on the substation design and their protection systems, which are the focus of this post.

Protection systems

So, what are protection systems? It’s a system that controls switchgear to detect and correct electrical faults. Generally, combining In a home, the switchgear and protection in a single unit, such as a fuse or MCB. The high voltage world is surprisingly similar, only the switchgear is much larger, and the protection systems separated.

50 Shades of GreyMatters

electricity-pylon

Recently, I received a call from a client in the Nordic region to review an earthing system problem – the client explained they had “… unexplainable noise on their clean earth” and could we help solve it? [Read more…] about 50 Shades of GreyMatters

Impossible Questions Answered Using Supercomputing Earthing System Software.

Safe Electrical Earthing Systems

The use of computing power to check, evaluate or inspect concepts in all walks of life. And in business, is increasingly common. Particularly in our field, earthing systems software for design and calculations.
Whether you are forecasting the performance of stock and shares or building an Electrical Generation plant. Engineering computer software. Aka, Earthing System software such as CDEGS allows us to stress-test designs and systems. Also,to evaluate their performance under given conditions.
so, being able to bring Supercomputing power and software into the mix. Therefore, is going to be able to answer previously unanswerable earthing, or electrical power questions.

Therefore, this piece aims to highlight a key limitation of current computer hardware. And also, how supercomputing is able to unleash the range and scope of previously impractical scenarios. And, for an investigation to resolve complex problems in our lives.
