As seen in the figure, three generators of 800 kW, 900 kW, and 1000 kW are connected in parallel. These generators feed the load of 380 kW. The frequency-active power graphs of the generators are given in the figure. According to this;
a. Calculate the operating frequency for the situation given in the question.
b. Calculate the power transferred by the generators to the load.
c. A three-phase asynchronous motor with 800 kW ohmic load and 600 kVA, 0.78 reverse power coefficient is connected to the system. Calculate the new operating frequency of the system and the active power of the alternators.
D. Do you think the generators in this system are suitable for parallel connection as in the figure?
