A Response to the UK Blackout
This article repeats one we have just posted on LinkedIn. So now that the dust has settled a bit after Friday’s UK Blackout ‘event’, what do we know and what have we learnt? I have put together a slightly longer post, which hopefully draws together some of the threads. At this point the post invariably […]
Generator Export Limitation Scheme – Their Role and Use
What is a Generator Export Limitation Scheme (ELS)? At Aurora Power Consulting we have been approach by a number of Clients looking for help on Generation constraint system, Export Limitation Scheme (ELS), G100 and flexible connections. These terms all mean more or less the same thing, and the chances are that if your involved in […]
Understanding DNO Network Reinforcement Requirements and Costs
DNO Network Reinforcement – A Rough Developers Guide Developers adding generation to the UK distribution network will be aware of the schedule problems and costs of the DNO’s connections, and in many cases the DNO connection costs can make or break a project. What many developers do not realise is that the cost and magnitude […]
ENA TS 41-24 and S34 – Earthing Standard For Earth Potential Rise Calculations
The New ENA earthing standards have finally arrived after a very lengthy consultation process. The two new documents issued are ENA 41-24 and ENA S34. For those of you not too familiar with this standard, it is used to calculate the earth grid impedance, earth potential rise and associated touch and step voltages, during a […]
Introducing G99 – Connection of Generation Equipment – A Replacement for G59
Are Your Generation Projects Ready for G98 and G99? If you work in power generation in the UK, whether that is thermal, solar, wind, hydro or any of the other technologies. You are probably aware that there is a new standard coming into force called ENA G98 and ENA G99. These new standards will radically […]
132kV Design – An Overview
This is a short post about the key ideas of 132kV design practices, too finish off the last of this series. In the UK, 132kV is the standard primary transmission voltage operated by the DNOs (it is also known as a sub-transmission voltage), the voltages above this point (275kV and 400kV) are full transmission voltages […]
33kV Design – An Overview
This is a short post about the key ideas of 33kV design practices. In the UK, 33kV is the standard primary distribution voltage, but for the most part is owned and operated by the DNO – some larger consumers or generating sites will receive a connection at 33kV if the local 11kV network cannot support […]
11kV Design – A Quick Overview
This is a short post about the key ideas of 11kV design practices. In the UK, 11kV is the standard secondary distribution voltage (a few places have 6.6kV – and this can be thought if as almost identical for design approaches) – the reason for this, is that it allows transmission of a fairly large amount […]
Electrical Engineering Consultants – How Can We Help?
How Can an Electrical Engineering Consultant Help? A question that is often asked by people is: “What does an electrical engineering consultant actually do?”, or ” Don’t you just write reports?”, ” Don’t you charge a lot of money to come up with something that doesn’t have any conclusions?”. These questions are fairly common, and […]
