A parallel generator is a generator system that operates alongside one or more other generators to provide a combined power output or to share the load demand. This configuration allows for increased reliability, flexibility, and efficiency in power generation, as it can adapt to varying energy needs. In parallel operation, synchronization is essential to ensure that voltage, frequency, and phase are matched across all generators. This setup is commonly used in industrial applications, backup power systems, and renewable energy installations.
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
Because millman's is used in parallel ckt of impedances and voltage sources
This question does not make any sense. "Real world" load, from the perspective of the power producing generator, can be reduced to a lumped resistance in series with a reactive component (either inductive or capacitive). In reality, the load connected to that generator has series elements and parallel elements.
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
That depends on if the two machines are of equal KVA rating and also what type of Generator Control (Isochronous or Droop) each of the machines uses.

When two generators are to be run in parallel, one generator is first started and some load is given. Then second generator is brought in parallel with the running generator (subject few conditions, like voltage, frequency, phase angle). First generator which is running is known as running generator, the second generator which gets connected is known as incoming generator
In a grid system all the alternators run in parallel, locked together in frequency.

generators are machines that convert machanical energy to electrical energy and could be AC or DC. if in a DC generator has it field armature connection in both series and parallel its said to be compound dc generator.
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator

Normal shaft generators do not have droop-control for frequency and voltage. Semiconductor (drive) based variable speed shaft generators may have those today.
It acts as synchronous motor by consuming power from the other generator....
Parallel generator earthing involves connecting multiple generators to a common grounding system to ensure safety and system stability. Each generator's neutral point is typically grounded, allowing for fault current to safely dissipate into the earth. This setup helps protect equipment and personnel from electrical faults, enhances system reliability, and ensures proper operation of protective devices. It's essential to follow local electrical codes and standards when designing and implementing the earthing system for parallel generators.
