It is called static excitation when you make use of solid state components like diode and thyristors to convert to pure dc and to use this dc for field excitation of synchronous generators. The field winding of synchronous generators can be excited by dc source only. It is called brushless excitation because use of carbon brushes are not made here.It is called dynamic excitation is when you make use of rotating brushes. Excitation is necessary to produce reactive power and also to regulate the voltage of synchronous generators.
A static excitation system uses solid-state devices to provide the field coil of a generator with the necessary excitation current. This system is more reliable and requires less maintenance compared to a traditional brush excitation system, which uses brushes and slip rings to deliver excitation current. Static excitation systems are also more flexible and offer better control over the generator's output voltage and reactive power capability.

What is the Difference between static equilibrium's and dynamic equilibrium?
Static equilibrium refers to a system at rest where all forces are balanced, while dynamic equilibrium refers to a system in motion where the rate of change is constant. In static equilibrium, objects are stationary, while in dynamic equilibrium, objects are moving at a constant speed and direction.
What instrument is used to measure the speed of an airplane?
A pitot tube is typically used to measure the airspeed of an airplane. It is connected to an airspeed indicator in the cockpit, which displays the speed based on the pressure difference between the pitot tube and static port.
How airspeed indicator works?
the airspeed indicator works by measuring the increase in air pressure caused by the moving aircraft
Name the instrument used for measuring the speed of an aeroplane?
The speed of an airplane is measured by a system known as the pitot-static system which compares the difference between the static air pressure that exists around the aircraft and the dynamic, or ram air pressure which is a function of the speed the aircraft is moving through the air. The devices used to gather this information are the static air port (which measures static air pressure) and the pitot tube (which measures ram air pressure). This differential is displayed on an instrument in the cockpit called an airspeed indicator (or ASI).
Why is a crackling sound heard when removing a jumper?
The crackling sound is likely due to static electricity being discharged when removing a jumper, causing a rapid release of electrical energy. This can happen when there is a difference in charge between the jumper and the components it is connected to, often creating a noise as the charge equalizes. It's generally harmless but indicates a buildup of static electricity in the system.
What are the seminar topics related to power system engineering?
static type thyristor controlled excitation system
What is the difference between continuous and discrete system?
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Differentiate between static and dynamic systems in linear system analysis?
If a system is static then it will be known as STATIC SYSTEM and if it is not static then its a common sense that it will be a DYNAMIC SYSTEM.
What is the Difference between static equilibrium's and dynamic equilibrium?
Static equilibrium refers to a system at rest where all forces are balanced, while dynamic equilibrium refers to a system in motion where the rate of change is constant. In static equilibrium, objects are stationary, while in dynamic equilibrium, objects are moving at a constant speed and direction.
Is a watch a static system?
If a system is static then it will be known as STATIC SYSTEM
What is the difference between cropping system and farming system?
difference between farming system and cropping system
Difference between system software and operating system?
difference between operating system and system software?
What is a excitation variable?
A variable that causes change in the output of a system. In a RC circuit, for example, the input V is the excitation variable
What will happen if polarity of dcin rotor in static excitation system are made opposite?
I am tyring to figure this out too. I think you will get no output from the generator but am not 100% sure. My F1 and F2 labels are missing am kind of scared to just guess.
