Types of Motions- As the object that oscillates is in motion, let us have a look at what are the different types of motions in oscillations. There are primarily three types of motions that are:
👉1-Periodic Motion
A motion that repeats itself periodically. For Example: the hands of the clock.
👉2- Oscillatory Motion
A motion which goes to and fro, and back, instead of full-motion. For Example: the clock’s pendulum.
👉3-Simple Harmonic Motion (SHM)
It is the type of motion in which the particle oscillates back ad forth in a straight line only. For Example: Bungee Jumping.
Oscillations are always present in the BPS due to the electromechanical nature of the electric grid. Under no significant external influence to the system, the grid oscillates at its natural frequencies for small perturbations such as constant changes in load. These oscillations are usually well-damped and contained; however, growing or high-energy oscillations can present system instability, potential equipment damage, safety concerns, and power quality issues. In addition to these natural oscillations, forced or “rogue” inputs to the system can also cause oscillations and should be detected and mitigated to the extent possible. It is important to clearly differentiate between the types of electromechanical oscillations that are present.
