What is the difference between droop speed control and isochronous speed control?

 

Droop speed control and isochronous speed control are two methods used to control the speed of prime movers, such as engines or turbines, in power generation systems. They are primarily employed in parallel operation of multiple generators to maintain stable power output. Here's the difference between the two:

1. Droop Speed Control: Droop speed control, also known as proportional control or speed-droop control, is a control strategy where the engine's or generator's speed is allowed to vary within a certain range around the setpoint. In a droop control system, as the load on the generator increases, the speed of the prime mover (engine) decreases, resulting in a lower power output. This introduces a speed vs. load characteristic that helps distribute the load among multiple generators in a proportional manner. It is often used in applications where load sharing is important, such as in interconnected power systems.
2. Isochronous Speed Control: Isochronous speed control aims to maintain a constant speed of the prime mover regardless of changes in load. In this control mode, the engine's speed is tightly regulated, and any change in load is met with an adjustment in fuel supply to ensure the speed remains constant. This control strategy is ideal for applications where maintaining a precise and consistent frequency is crucial, such as in standalone power systems or applications requiring high stability.

 

How drop speed system works in gas turbine?

 

Eagle, the topic of Droop Speed Control and Isochronous Speed Control has been covered MANY times on Control.com. There is a Search feature at the top of every Control.com webpage which can be used to search all of them.

 

Eagle, if you're working on a GE Mark* turbine control system controlling and protecting a GE-design heavy duty gas turbine the topic of Droop Speed Control specifically for these control systems and machines has been covered MANY times before. Look for TNR and TNH and FSKRN1 and FSKRN2.

 

Thanks dear

 

Dear,

If you need clarification we can help. If you have doubts, we can’t help.

 

Eagle,

Please be aware that Eagle's AI-generated regarding Droop Speed Control IS NOT FULLY CORRECT. No machine (generator and its prime mover) slows down when it is being loaded when it is synchronized to a well-regulated AC power system/grid. NO MACHINE. The ONLY TIME a machine slows down when being loaded is when it is the only machine providing power to some load or loads and it is being operated in Droop Speed Control mode without any other means of monitoring and correcting for frequency deviations. The AI-generated response is, however, correct when it says that Droop Speed Control is [strictly] proportional control--meaning it doesn't have any method for returning the frequency to normal when it deviates from normal--it depends on other methods for controlling frequency. Droop Speed Control is the method that allows multiple machines (generators and their prime movers) to control frequency of the generator's output and of the AC power system it is connected to.

   It seems AI generated an answer. Right? I have seen many of my friends are using AI technology to write their essay assignments. But I don't prefer it because I don't trust it. Instead of that, I prefer to take help from online essay writer who can write paper for me and I already found a website where I found the 7 best essay writing service which is located in USA.

It seems AI generated an answer. Right?

 

It definitely IS an AI-generated posting. It’s very obvious because the typical falsehoods which appear in many textbooks and reference materials (including some equipment manufacturer’s manuals and instructions!) are present in this AI-generated posting.

But, if you can’t beat ‘em, join ‘em,right?

I hope the moderators remove this post.
