משוואת הנדנדה
The Swing Equation is crucial for understanding the dynamics of generating units, such as a three-phase synchronous generator.
It describes rotor motion ...
מודל מכונה סינכרוני פשוט
The Synchronous Machine Model is crucial in transient stability studies.
It represents a synchronous machine with a constant internal voltage behind its ...
יציבות מרובת מכונות
In an N-bus power system with M synchronous machines, loads are modeled as constant admittances, and network nodal equations are formulated.
The ...
דגמי מכונות טורבינות רוח
There are four types of wind turbines. Types 1 and 2 are induction machine models, where stator windings induce AC rotor currents via relative motion ...
בקרת מתח גנרטור
In synchronous generators, the exciter delivers DC power to the rotor's field winding.
Older models use a rotor-driven DC generator as the exciter, ...
בקרת טורבינה-מושל
Turbine-generator units in power systems store kinetic energy due to their rotation, which is released when the load increases.
The electrical torque of ...
בקרת תדר עומס
In sudden power surges, load-frequency control stabilizes the grid. LFC's goals are to nullify steady-state frequency error after load changes and ...
