What is droop on an electrical grid?

Answer 1

Electrical power is a little bit like the air you breathe: You don't really think about it until it is missing. Power is just "there," meeting your every need, constantly. It is only during a power failure, when you walk into a dark room and instinctively hit the useless light switch, that you realize how important power is in your daily life. You use it for heating, cooling, cooking, refrigeration, light, sound, computation, entertainment... Without it, life can get somewhat cumbersome.

Power travels from the power plant to your house through an amazing system called the power distribution grid.

The grid is quite public -- if you live in a suburban or rural area, chances are it is right out in the open for all to see. It is so public, in fact, that you probably don't even notice it anymore. Your brain likely ignores all of the power lines because it has seen them so often. In this article, we will look at all of the equipment that brings electrical power to your home. The next time you look at the power grid, you will be able to really see it and understand what is going on!

Answer 2

Droop Speed Control is a speed control mode of a prime mover driving a synchronous generator connected to an electrical grid

Answer 3

I have never heard of "Droop" associated with the grid..... As previously suggested it maybe the transmission voltage drop!!! However if you are referring to "Speed Droop" That is the percentage of speed reduction that a generator at the power station will pick up should the Hz sag. Generally it is 3% this means that on a 60Hz supply the generator will pick up, up to 3% of its rated power output without operator adjustment.

Answer 4

Voltage drop, caused by resistance in the transmission lines and high current draw at the points of use. Therefore the voltage measured at the point of use is significantly lower than at the generator or transformer.
