What is difference between terminal voltage and generated voltage?
Generated Voltage is the voltage developed across the terminals of the Generator without any load connected. Suppose a Generator is rotating at synchronous speed so its winding will link the changing magnetic flux and because of this an emf will be developed across the terminal as Faraday's Law of Electromagnetic Induction suggests. So this generated voltage is often called Excitation voltage.
But now suppose you connect a load across the terminals of the Generator. In this case current will start flowing and the Voltage across the load will now be
V = E-IZ where E is the Excitation voltage, I the current and Z the impedance of the Generator winding. Here V is the terminal voltage which load face. Thus you see how Generated voltage and load terminal voltage is related
