Richard: Sorry, I did not write the initial question. I was the one who stated that the power plant was being run as a large synchronous motor. The reason being that it was being used as storage for reactive power to normalize for disturbances in the transmission network. If I remember correctly, these were called something like synchronous stabilizers. To the Transmission Line it looks like a Thevenin equivalent of a large capacitor (or inductor in other cases). It acts as a generator in this case supplying VARs if needed. These storage devices were first used to correct phase errors around the 1920s. Nowdays, switching capacitor banks are easier and cheaper to use. Phase error causes loss of real power because the current and voltage are out of phase. --------------------------------------------------------------------------- Shishin _Squish_ Yamada Northwestern University Evanston, IL EE Class of 1991 --------------------------------------------------------------------------- Down with Sadam!
