Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc.
there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).

What happens when heavy loads are connected to an electrical generator?
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
How to compute the minimum load of 16 MW generator?
A generator, rated at 16 MW, should be able to continuously supply a load of 16 MW. You don't need to compute its 'minimum load', because the minimum load will be zero watts! In other words, you can run the generator with no load whatsoever if you wish to waste fuel.The point is that the power supplied by a generator is determined by the load, NOT by the generator itself -so it is important that the generator is capable of supplying the maximum load applied to it. A generator's 'rated power output' simply tells us the maximum load it is capable of supplying.
What will happen when excitation system is removed in the on load condition of synchronous generator?
When the excitation system of a synchronous generator is removed while it is on load, the generator will lose its ability to maintain voltage regulation. This can lead to a drop in terminal voltage, resulting in the generator being unable to supply the required reactive power to the load. Consequently, the generator may operate in an unstable condition, potentially leading to a loss of synchronism and the risk of overheating or damage to the machine. In extreme cases, it could result in a complete system failure or blackout.
What is the function of capacitor in an electric generator?
In an electric generator, the function of a capacitor is to provide reactive power and improve the power factor of the generator. When a generator is connected to a load, the load may have a combination of resistive, inductive, and capacitive components. Inductive loads can cause the power factor of the generator to decrease, resulting in lower efficiency and voltage regulation. By adding a capacitor in parallel with the generator, the reactive power generated by the capacitor can offset the reactive power of the inductive load, leading to improved power factor correction. This helps to enhance the efficiency of power transfer and stabilizes the voltage. The capacitor absorbs and supplies reactive power, reducing the strain on the generator and ensuring a steady and efficient supply of electrical energy.
What is the basis of a generator load?
The load on a generator is a general word for whatever device is connected to it to use the power that is being generated.
When a generator is running and if no electrical load is attached to it where do the electrical energy generated go to?
If no electrical load is attached to a running generator, the electrical energy generated typically backs up onto the grid or remains within the generator's internal electrical system. It is important to have a load connected to a generator to ensure efficient and proper functioning.
What is a group name for dry cell battery and generator?
Electric Source You hook both to an electric Load.
What are the differences between emf and voltage drop?
emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.
What happens when heavy loads are connected to an electrical generator?
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
What does a conductor do in a dc generator?
It is a conductor, it conducts the electric current generated to the load that is being supplied with power.
Why terminal voltage of a self excited shunt generator decreases with an increase of load?
The terminal voltage of a self-excited shunt generator decreases with an increase in load due to an increase in voltage drop across the internal resistance of the generator. As the load current increases, the drop across the internal resistance also increases, reducing the output voltage available at the terminals. This effect is known as voltage regulation and is a common characteristic of self-excited shunt generators.
How is a Load applied to a ac generator?
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
How Regenerative Braking Works?
As the brakes are applied in an electric vehicle, the motor is used in reverse (I.E. an electric generator) to recharge the battery from the kinetic energy of the vehicle. The greater the load on the generator, the greater the emf force which opposes the generators turning.
How can you increase the amount of electric current produce by generator?
To increase the amount of electric current produced by a generator, you can increase the rotational speed of the generator, increase the strength of the magnetic field within the generator, or increase the number of turns in the generator coils. These methods will result in a higher induced voltage and therefore a higher electric current output.
What is isochronous and droop in generator parralel operation?
isochronous means generator zero drop during parale operationdroop means the generator at 100% load the frequency is50 HZand at no load have more tahn 5oHz eg.. generator set at 4% droop it means at no load the frequency is 104% x 50Hz.
What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection. Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
