According to the consumption estimate at the end of the period, Ekip Power Controller will take different actions:
– if the value estimated is greater than the power set as a target, Ekip Power Controller makes the decision to disconnect one
of the loads controlled from the power supply, or to connect a generator;
– if the value estimated is equal or slightly less than the average power set as a target, Ekip Power Controller makes the
decision to leave the conditions of the controlled loads and generators unchanged;
– if the value estimated is significantly lower than the average power set as a target, Ekip Power Controller makes the decision
to reconnect one of the loads controlled to the power supply, or switch off a generator if one or more of these have been
switched on previously.
This operation is carried out cyclically each time by calculating a new estimate: therefore, if the estimate of power consumed
continues to be too high despite the fact that a load has been disconnected, Ekip Power Controller will proceed to disconnect
another and so on, until the power limit is respected. In this way, the number of connected or disconnected loads varies
dynamically, and always with the guarantee that only the minimum number needed to respect the power limit are disconnected.
Priority of loads
If the decision made is to disconnect or re-connect one of the loads controlled, Ekip Power Controller proceeds according to
an established order: the load indicated as the first will be that of least importance, or that for which a temporary period of
deactivation is acceptable; the load indicated as the second will be the next one in order of importance, and so on. The loads
that have been disconnected in that order will be later re-connected in the reverse order, beginning with the load that is most
important for the installation. In this way, the impact on the production process can be minimized, limiting the disconnection
time for loads of the highest priority. Furthermore, by gradually connecting and disconnecting the loads in order of priority,
voltage imbalances and consumption peaks affecting the network are avoided.
Protection of the installation
Ekip Power Controller can be integrated perfectly into the installation’s protection devices. In fact, if one of the controlled
circuit-breakers opens due to an overcurrent or by manual operation, Ekip Power Controller considers the load unavailable until
the operator resets it, making it available again. In this way, safe operation of the installation is always guaranteed.
