A low or medium voltage electric power distribution network comprising:
- at least a P&C device (IED1, IEDN),
- a computer station which communicate with said at least a P&C device through a communication network;
- characterised in that said computer station comprises first computerised means for executing, according to a batch processing mode, downloading sessions of software packages (F1, FN) to said P&C devices in order to upgrade the software of said at least a P&C device, said at least a P&C device comprising second computerized means for executing a procedure for safely managing the software upgrade in said at least a P&C device.
A method for performing a software upgrade in at least a P&C device of a low or medium voltage distribution network, said at least a P&C device communicating with a computer station through a communication network, said computer station executing, according to a batch processing mode, downloading sessions of software packages (F1, FN) to said P&C devices in order to upgrade the software of said at least a P&C device, wherein it comprises the following steps:
- receiving the software package downloaded by said computer station;
- and
- storing the software package downloaded by said computer station;
- and
- saving a back-up copy of the old software that is already resident in said at least a P&C device;
- and
- checking whether the software package downloaded by said computer station have been correctly stored;
- and
- if the software package downloaded by said computer station have not been correctly stored, recovering said back-up copy of the old software, said old software being used to continue the normal operations of said at least a P&C device.
