Generator Synchronization Lab Post Lab Questions 1. What are the synchronization conditions that must ideally be met before synchronizing a three-phase synchronous generator to an ac-power network? 2. What are the main negative effects of improperly synchronizing a synchronous generator to an ac- power network? 3. Is it possible to vary the frequency and voltage at the terminals of a synchronous generator/motor when it is synchronized to the ac-power network? Explain why or why not. 4. What is the effect of increasing the speed of a synchronous generator when it is connected to an ac-power network? 5. What is the effect of increasing the field current of a synchronous generator when it is connected to an ac-power network? In class we are studying the synchronization of a firefly with an external signal with phase?. Now consider the synchronization of two different fireflies with each other. Suppose that each firefly tries to match the phase of the other firefly. So if the phase of the first firefly is ?1 and the phase of the second firefly is ?2, and their natural frequencies are respectively ?1 and ?2 then ??1 = ?1 + A1 sin(?2??1) ??2 = ?2 + A2 sin(?1? ?2) (a) Analyze the synchronization of two fireflies in the same way as we analyzed the firefly's synchronization with an external oscillator. Calculate the conditions (that is what constraints the parameters ?1, ?2, A1 and A2 need to obey) under which the two fireflies are able to synchronize. (b) Suppose that the two fireflies do succeed in synchronizing (that is, their phase difference reaches some stable equilibrium). What is their common frequency? Exercise 3. In class we are studying the synchronization of a firefly with an external signal with phase e. Now consider the synchronization of two different fireflies with each other. Suppose that each firefly tries to match the phase of the other firefly. So if the phase of the first firefly is and the phase of the second firefly is 62, and their natural frequencies are respectively w and w then 0+A sin(02-01) 02=w2+ A2 sin(01-02) (a) Analyze the synchronization of two fireflies in the same way as we analyzed the firefly's syn- chronization with an external oscillator. Calculate the conditions (that is what constraints the parameters wi, w2, A1 and A2 need to obey) under which the two fireflies are able to synchronize. (b) Suppose that the two fireflies do succeed in synchronizing (that is, their phase difference reaches some stable equilibrium). What is their common frequency?
