Question

A synchronous generator with inertia constant, H, operates in steady state with steady state rotor angle δ0. The steam turbine delivers rated mechanical power Pm to the generator. Following a three-phase short circuit fault at the generator terminals, the generator’s rotor accelerated at the rate of π/6 rad/s2. The fault lasted 2t=s.
i)
The maximum allowed increase in power angle during the fault that would ensure generator stability is π/6 rad. Will the generator retain stability after the fault clearing?
ii)
Calculate the maximum electrical power that the generator can deliver to the network.

e) A synchronous generator with inertia constant, H, operates in steady state with steady
state rotor angle &. The steam turbine delivers rated mechanical power Pm to the
generator. Following a three-phase short circuit fault at the generator terminals, the
generator's rotor accelerated at the rate of 7/6 rad/s². The fault lasted t = √2 s.
1)
The maximum allowed increase in power angle during the fault that would
ensure generator stability is π/6 rad. Will the generator retain stability after the
fault clearing?
11)
Calculate the maximum electrical power that the generator can deliver to the
network.
