STEADY STATE,TRANSIENT AND DYNAMIC STABILITY
Steady state stability is the ability of an electrical machine or power system to regain its original state after its operation or we can say that stability is the ability of a system to regain its original state after a disturbance occurs. We know that the power is obtained from the synchronous generators which has a synchronism operation.
The generator is synchronized with a bus provided both of them need to have the same voltage ,frequency and phase .So basically steady state stability is to attain stability without loosing its synchronism.
Stability is basically of three types Steady State,:-
Transient and Dynamic Stability
Basically the steady state stability are consent to small gradual changes only. Here concentration on restricting the bus voltages close to their nominal values are emphasized . It is to be ensured that phase angles between two buses are not too large and check for the overloading of the power equipment and transmission lines. These are often done using power flow studies. Transient Stability is one of a major factor as it involves the major disturbances. On getting a large disturbance the synchronous alternator,the machine power (load) angle changes due to sudden acceleration of the rotor shaft. The dynamic stability involves small scale disturbances . These small disturbances occur due regular fluctuations in loads and generation levels. In case of interconnected power system, the fluctuations can lead catastrophic failure as this may force the rotor angle to increase the steadily.

Power system
i want power system dynamics and stability material
Differentiate between steady state transient and dynamic stability
Can i have a detailed explanation of induction generator and its applications??
what is difference between transient , steady and dynamic state for power system
In acoustics and audio, a transient is a high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech.Here in this article 3 states are explained.
