Sir Georges,


Let talk about power generation,

I had done some visit to Power Generation Control Room during my university year. I donno if this is concept is wrong or correct. The Technician said that, the generator produce active and reactive power. But, production of reactive power is limited to provide extra life span to the generator. In addition, he said that, therefore on the transmission line system, utility company design reactor to supply reactive power into the transmission line to recap the usage of reactive power in the transmission and improve power quality in term of power correction.

dear Mr. zulfahdli ;

As we know all, any Electrical Power Generation Center generates ” Apparent Power ” in ” kva “, that will be divided into ” Active  &  Reactive Powers ” depending on the Power Factor’s value of the loads, where the resistive loads consume only ” Active Power “, and the ” Inductive & Capacitive Loads ” consume both kind of power ” Active & Reactive ” depending on the Power Factor’s value.

Beside , in most of countries, the Utilities oblige the end users of important values of Electric Energy to install the convenient Capacitors to improve the Power Factor’s Value of there sites till a predefined value ( ≥0.93 ). Also, the utilities use ” Capacitors and/or Synchronous Motors ” to improve the Power Factor value in the Transformation & Generation Centrals.
