Transient Stability and System Controls
스윙 방정식
The Swing Equation is crucial for understanding the dynamics of generating units, such as a three-phase synchronous generator.
It describes rotor motion ...
단순화된 동기식 기계 모델
The Synchronous Machine Model is crucial in transient stability studies.
It represents a synchronous machine with a constant internal voltage behind its ...
멀티머신 안정성
In an N-bus power system with M synchronous machines, loads are modeled as constant admittances, and network nodal equations are formulated.
The ...
풍력 터빈 기계 모델
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 ...
발전기 전압 제어
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, ...
터빈-조절기 제어
Turbine-generator units in power systems store kinetic energy due to their rotation, which is released when the load increases.
The electrical torque of ...
부하 주파수 제어
In sudden power surges, load-frequency control stabilizes the grid. LFC's goals are to nullify steady-state frequency error after load changes and ...
