How is the use of power factor correction techniques, an energy efficiency measures?
Notify me if my answer is selected or commented on.
Power Factor Correction (PFC) is a challenging subject. There are many myths, misconceptions, and much misinformation in general circulation. Nevertheless the short answer is that PFC can contribute to energy efficiency. The reason is easy to understand. A low power factor results in more current being required to generate the same amount of delivered power. This increased current results in power loss, and thus inefficiency, on the way to the load. Thus if the power factor can be improved at or near the load, then energy loss will be reduced resulting in a more energy efficient installation.
Power factor correction is generally concerned with displacement PF, what happens when we introduce solar PV to offset a portion of the kW load, will this decrease the PF on the meter or does it increase the PF?
How about the true PF? What happens when we have harmonics in the electrical system due to non-linear loads will this effect the performance of the corrected PF load?
do we need to add more Capisators cabacities for the correction the PF of motors?
There are hand held, single and three phase power meters that give you readings of power factor cos@ and KVAR, you must connect to the net a capacitor bank of the same o more KVAR. I prefer use electronic devices as variable frequency drives or energy saving soft starters, if we are looking to get best energy efficiency. Greetings of Rodolfo Lopez Vega, Energy Savings, electric motor drives expert and consultant email@example.com . I have got a lot of energy savings replacing traditional starting systems by frequency drives in water pumping systems, and getting a power factor near to 1 (with all capacitor disconnected by the automatic Power factor controller).
