Our power plant has Oil Fired Boilers & Steam Turbines (4 x 300 MW = 1200MW). Our national grid has large variations in grid frequency since we have extensive difference in between demand and supply of power.
We have 50 Hz system. When grid gets over loaded, frequency starts declining & mostly it gets around even 48.5Hz. Consequently, our generators also respond to this change according to droop setting (droop setting=5% on all 4 units). BUT sometimes our generator MW output hits +320MW or even more.
I just want to inquire, if we make our generators output (MW) FREQUENCY INSENSITIVE for >= 300MW i.e. it won’t respond to frequency change when it’s already operating at 300MW then IN SUCH CASE, WHAT WOULD BE ITS HARMFUL IMPACT ON OUR GENERATOR/TURBINE ?
