Generator Protective Relay
Generator Protective Relay
(OP)
As you know for large size Generator #40 relay which is loss of field relay is actually a distance relay looking into the Gen. and in case of LOF the impedance seen by the realy will fall into the relay char. I need to know how I can make the relay to look into the Gen. Not on the load side.

If all you want to see is the generator itself, use the CTs on the terminals and look back into the generator. If you want to see both the generator and the transformer, use CTs on the neutral end.

For the distance element you can set the directionality but how I can make my computer model directional? What elements do I need to consider to make it look only in the direction I want? The computer model is based on sensing current and voltage at the relay piont and using some digital techniques to calculate Resistance and Inductance, As I mentioned before it works ok with power line.
