As an engineer, and since taking over Hinckley power nuclear power plant, you are assigned to install new EHV substations. It has been deemed that the previous substations have been in use too long and are too old and dangerous. Consequently, all new equipment is being supplied and it is your responsibility to design a suitable substation to perform the task of distributing the energy from Hinckley point onto the grid. What equipment would you suggest would need to be in the substation in order to provide the energy from the power station onto the grid, and what problems do you think you will run into both on a technical and logistical level? Discuss the protection equipment in use and their function. Analyse your system of protection for this substation and prove it will adequately protect against overcurrent and short circuit situations. Validate the systems that may be put into place to limit the size of some protection devices if a second substation were built to take power to a new housing site nearby. How does a distribution network function and what, and how are the problems of network transmission/ distribution overcome? What is the Ferranti effect, how do we get around it? What is ferroresonance? What dangers do these effects pose to both systems and maintenance staff? Protection equipment also comes with its own issues. A CB is just one example. What issues are these? (Hint: Construction? Materials etc.?)
