PPC

The PPC allows you to regulate active power in an open or closed loop. In an open loop, the active power measured at the interconnection point should be equal to its defined rating, minus plant power losses. In a closed loop, availability of the command reference depends on sufficient active power being available in the plant.

Active power can be adjusted automatically in response to high- or low-frequency events.

The PPC allows you to regulate reactive power in an open or closed loop. In an open loop, the reactive power measured at the interconnection point should be equal to its defined rating, minus plant power losses. In a closed loop, availability of the command reference depends on sufficient reactive power being available in the plant.

This control mode is implemented in a closed loop. It inputs are the active power measured at the interconnection point and the adjusted reference value of the power factor obtained at that point.

Depending on the voltage measured at the interconnection point and the defined voltage setpoint, the PPC controls the equipment that makes up the plant system based on the value of the inductive or capacitive reactive power supplied as required to reduce or increase the voltage reading at the interconnection point in order to reach the adjusted reference setpoint.

Reactive potential can be adjusted automatically in response to high- or low-frequency events.
