A power distribution grid for a facility, such as a data center, is located within the facility. The power distribution grid includes a plurality of power transport elements arranged in a grid pattern and nodes located at intersections of the grid pattern. Electrical loads are supplied power via respective nodes of the power distribution grid. Also, each node is supplied power from more than two transport elements, such that one or more transport elements can fail and electrical loads connected to a particular node associated with the failed transport elements continue to receive electrical power supplied to the particular node from at least two different transport elements.

This power supply unit of a control system outputs a notification signal to a calculation unit when a time in which an input voltage becomes smaller than a threshold voltage exceeds a prescribed first measurement time. When detecting that a predetermined second measurement time has elapsed after the notification signal has been received, the calculation unit outputs an instruction signal instructing the execution of a process before a stop in preparation for a prescribed stop of power supply, and executes the process before the stop in place of the current process. Settings of the threshold voltage and the second measurement time are configured to be changeable by means of an external operation.
