Synchronisation now complete!

normanton · Jul 27, 2014

You may remember a post a while back about how our total load up the hospital was getting uncomfortably close to its limit whilst running on generator. Well, after a long 6 months we've finally syncronised Geni 1 and Geni 2. We are now capable of running a load of 2.5MegaWatt. Hallelujah! But, in doing so, have discovered that theres actually a crash point in one of our substations where if one of our switches is closed (on generator test), mains and generator can actually meet. Bad news for the generators. Just gets better lol .. Next stop... Castell key installation! :6:

Well recently saw one that had 2 substations each with its own hv/lv transformer 2 generators one fed sub 1 via 4x4c 240mm and the other fed sub 2 via 4x4c 240mm and an lv link 4x4c 240mm between sub 1 & sub 2 .If you lost hv & gen at one sub you could isolate them and usethe lv link to feed the sub

Come on, synchronising is easy isn't it?

Join the star points, connect a couple of lamps between the lives, fettle the governor a bit so the flashing slows down and then throw the switch when the lights go off.

What could possibly go wrong? (apart from one or both generators tearing themselves to pieces that is)

I’ve been trying to find a picture of a generator where the shaft had sheared off due to poor synchronisation. It’s lurking somewhere in the back hole that is my PC.

I've never seen it happen but have heard a story of a temp supply generator jumping and landing on its side when someone botched a synchronisation.

I can imagine how well that phonecall to the hire company went! 'So you decided to save money on a proper load share controller did you?'
