How we can differniate the overhead lines feeded by hydro power stations & thermal power stations
1 3568We 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).

how was your last weekend.
we have a lot of model of rectifier but thyristor rectifier is the most rectifier that use in power system. Do you know why this rectifier is used?
