POWER FAILURE IN EAST ANGLIA

CliveS
What happened?   Why did the grid cascade trip and not isolate the immediate network?  Natgrid is NOT responsible for failure of British rail or hospital emergency supplies and MUST NOT fiddle the protection around trying to keep key areas/cities railways on!! 

Just shed the immediate area in this case Norfolk and Suffolk.  We do not need an expensive legal inquiry or someone to blame;  just reset the protection and shed the nearest area to the fault.  Sorry for the RANT.

    Just had a further thought.  British Rail should apply for government funding to install say a GWatt of emergency generation plant which could be spread all over Britain and Natgrid could then shed the railways first; knowing that the railways have that emergency generation to keep them going.A few minutes delay is better than hours of disruption.

     Further, British Rail should always include a single hybrid diesel electric unit on each intercity train so that in case of an electrification line fault, the driver is able to continue slowly towards his destination. NOTE signalling and points are all assumed to be on a separate DC battery backup supply.
