    Maximum Acceptable Step load - LM2500 GTG

    We have three Gas Turbine Generators (GTGs) of the GE (LM2500+G4) model in parallel, each with a site rating of approximately 27.5MW. Inquiring about the maximum acceptable step load for this type of GTG, I reached out to GE for guidance and yet to get a response. However, I'm seeking additional...

    "Isochronous Load sharing" Vs Droop Mode

    Say, there are 4 machines not connected to grid. The four machines all worked in "isochronous load sharing mode" with the PMS and other controllers. What stops the governor from fighting one another in this mode? It seems all the machines talk to each other as to who will respond to the system...

    Why Generator is rated at 0.8 PF?

    Why Generator is rated at 0.8 PF? Is it because the generator set manufacturers assume that most overall loads are somewhat inductive and apply an arbitrary rating of 80% PF.

    Generator Rating Vs Turbine rating

    Why Gas turbine drive Generators have higher output rating than the Gas turbines? is it the same for Steam/Diesel/hydraulic turbines?

    Quadrature droop Vs Cross Current compensation - AVR Controls

    1. What is the difference between quadrature droop Vs cross current compensation? Is cross current compensation method for AVR control equivalent to "Isochronous control" of governor? 2. Is the term line droop compensation same as the term "Line drop compensation"? 3. Is it possible for multiple...
