1.2 Definitions
The following definitions might be useful to understand some of the sections in this manual.
1.2.1 4-Quadrant
Regulator.
The regulator is capable of performing the measurement and regulation functions when the active power is
transferred from the grid to the loads (common case in a consumer installation) or when the load is
transferred to the grid (this is the case of installations with generators that not only allow the consumption of
energy, but can also export and sell energy).
1.2.2 FCP System (FAST Computerized Program).
This system controls the connection sequence of the different stages, tending to minimise the number of
operations and matching the usage times of the different stages to achieve the determined final power
demand. The operations are carried out in such a way that, in the case of stages with an identical power, the
stage that has been disconnected the longest is connected when there is demand and the stage that has
been connected the longest is disconnected in the case of a surplus.
