Q2. Suppose that a synchronous generator is connected to an infinite bus. Base frequency of the system is 50 Hz, the voltage of the infinite bus is 1.03 pu, the voltage of the machine is 1.01 pu, the rotor angle under equilibrium is 37.5°, the equivalent line reactance is 0.2945 pu. Find the oscillation frequency of the machine if it is subjected to small disturbances. (Take H=2.1) the voltage of the infinite bus is 1.03 pu voltage of the machine is 1.01 pu rotor angle under equilibrium is 37.5° equivalent line reactance is 0.2945 pu Take H=2.1 Base frequency of the system is 50 Hz You need to take these values into account with formulas.
