Transient Stability and System Controls
A equação do swing
The Swing Equation is crucial for understanding the dynamics of generating units, such as a three-phase synchronous generator.
It describes rotor motion ...
Modelo de máquina síncrona simplificada
The Synchronous Machine Model is crucial in transient stability studies.
It represents a synchronous machine with a constant internal voltage behind its ...
Estabilidade de várias máquinas
In an N-bus power system with M synchronous machines, loads are modeled as constant admittances, and network nodal equations are formulated.
The ...
Modelos de máquinas de turbinas eólicas
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 ...
Controle de tensão do gerador
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, ...
Controle do Regulador de Turbina
Turbine-generator units in power systems store kinetic energy due to their rotation, which is released when the load increases.
The electrical torque of ...
Controle de frequência de carga
In sudden power surges, load-frequency control stabilizes the grid. LFC's goals are to nullify steady-state frequency error after load changes and ...
