We have a 12MW power plant & we inject 5-6MW power to Orissa GRID. For this we have a 33KV/11KV switch yard having 12.5MVA power transformer. Some times we draw power during emergency. It is observed that during Export or Import for load less than 500Kw the power factor is decreasing to 0.3 . This is happening only during export or import. During island condition TG power factor OK.Our capacitor bank is provided with our Power plant auxilliary load. Please suggest how I can we improve our power factor during low load (GRID).

There is no such thing as a Generator. All power generating devices are Alternator since both generate alternating current since this is the only way electrical power can be generated. In "generators" the alternating current is converted into DC inside the housing of the "generator" in order to give out DC Do you agree? If not please educate me. How else is DC generated if not like above?
