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.


Why might you be unable to synchronize the power generators in parallel?

Inability to synchronize power generators either means you are doing it wrong, or there is something wrong, some malfunction.Synchronization procedure depends on the particular design, but the generalized procedure is to match voltage and RPM, with the second (to-be-synchronized) generator slightly higher in both voltage and RPM, and close the circuit right at the point of synronization as indicated on a synchronometer. Immediately after closing the circuit, you want to bring the excitaion voltage and power input up, so as to take load, otherwise the second generator will become a load instead of a generator.This procedure works in the normal case where the first generator is much larger than the second generator, i.e. the first generator is a power distribution grid. Cases where two equal generators are being synchronized are different. Again, consult the documentation.If the procedure is being followed correctly, then you need to troubleshoot.


What does el impermeable mean?

Unable to be penetrated. Not permeable.


What does a Power plant coma stand for?

A "power plant coma" typically refers to a state of inactivity or stagnation in a power plant's operations, often due to mechanical failures, regulatory issues, or lack of demand. It can also indicate a prolonged shutdown where the plant is unable to generate electricity, affecting its efficiency and profitability. The term highlights the importance of maintenance and operational readiness in energy production facilities.

Need labeled diagram of a generator?

I'm unable to provide visual diagrams. However, a generator typically consists of a coil of wire rotating within a magnetic field, creating an electric current. The key components include the rotor (coil of wire), stator (magnetic field), and an output terminal for the electrical energy produced.


What happens to windmills when no wind?

When there is no wind, windmills are unable to generate electricity. They rely on wind to turn their blades and in turn, generate power through a turbine. Without wind, the windmill remains stationary and cannot produce energy.


Could you show a calendar for the month of April 1958?

I'm unable to show a calendar for a specific month in the past. However, you can easily find an online calendar generator that allows you to customize and view calendars for any month and year. Simply input the month and year you're interested in, and it will generate the calendar for you.

Why are steam turbines unable to produce direct current?

Steam turbines cannot directly produce direct current (DC) because they inherently generate alternating current (AC) due to the rotating motion of the turbine blades. To convert this AC output to DC, a device called a rectifier is needed. Rectifiers use diodes to change the flow of current, converting the AC produced by the steam turbine into DC suitable for most applications.

During the absolute refractory period along an axon membrane of a neuron?

During the absolute refractory period, the neuron is unable to generate another action potential, regardless of the stimulus strength. This is because sodium channels are inactive and unable to open. This period ensures that action potentials are discrete and travel in one direction along the axon.


Are flies cold blooded?

Yes, flies are cold-blooded insects, meaning they rely on their environment to regulate their body temperature. They are unable to internally generate heat like warm-blooded animals.


What happens to windmills when there is no wind?

Windmills do not operate without wind. When there is no wind, windmills are unable to generate electricity or perform their intended function. They rely on the kinetic energy from the wind to turn the blades and produce power.
