Transient Stability and System Controls
Уравнение свинга
The Swing Equation is crucial for understanding the dynamics of generating units, such as a three-phase synchronous generator.
It describes rotor motion ...
Упрощенная модель синхронной машины
The Synchronous Machine Model is crucial in transient stability studies.
It represents a synchronous machine with a constant internal voltage behind its ...
Стабильность работы нескольких машин
In an N-bus power system with M synchronous machines, loads are modeled as constant admittances, and network nodal equations are formulated.
The ...
Модели ветряных турбин
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 ...
Управление напряжением генератора
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, ...
Управление турбиной-регулятором
Turbine-generator units in power systems store kinetic energy due to their rotation, which is released when the load increases.
The electrical torque of ...
Регулирование частоты нагрузки
In sudden power surges, load-frequency control stabilizes the grid. LFC's goals are to nullify steady-state frequency error after load changes and ...
