Abstract:
An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation which is capable of indicating a level of reactive power drawn by the load and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. A first embodiment of the system is based on a measured level of current and the effect on the measured level of current of adding compensating capacitors of selected capacitances to the power line. A second embodiment of the system is based on a measurement of phase angle of the power drawn and the addition of a calculated combination of capacitors to the power line to compensate for a measured level of reactive power.

In particular, the system measures the phase angle of the power drawn and calculates a combination of capacitors to connect to the power line to compensate for a measured level of reactive power.

Abstract:
An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation using a power measurement integrated circuit, the parameter being capable of indicating a level of reactive power drawn by the load, and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. In a first embodiment of the invention, the combination of power factor compensating capacitors is calculated from a signed value of reactive power drawn by the load. In a second embodiment, the compensating capacitor combination is calculated from a value of power factor for the load which is calculated from a ratio of an active power value to an apparent power value.
