Hi
I have the following situation:
(Please see attached pic)
I want to know if equation (4) i have written is correct.
What is confusing me is that, I remember being told in circuit analysis that each energy storage element should have its own state variable.
But in this situation when I...
At the time I was asking this question I don't think I had grasped the question correctly even myself.
What I initially wanted was to eliminate V_T.
But as a consequence of doing this I found out I had to/ could write I_1 in terms of I2 and I3.
I wasn't sure if this second part of replacing...
I have a system with three inductors connected together at a common point.
The unconnected ends of each inductor is connected to an independent voltage source.
Basically I want to get three expressions for the dynamics of the currents with V1, V2 and V3 as inputs.
i.e. i need to eliminate the...
I have the following system I got from a book, which models the dynamics of two masses connected by a shaft.
The system is given below:
And the equations given in the book for this system is below:
The nominal speed is w0.
And the interest here is the deviations from the nominal for mass...
I'm trying to implement a basic PLL. The diagram is given as follows:
Where the transfer functions are given as follows:
To implement the PLL I need it to be as follows:
How do I determine H(s) from the transfer functions that are given?
Thank you for your help
Ok but I am still confused:
a. Its an inductive line how can it be capacitive? (is it capacitive because the terminal voltage magnitudes are the same?)
b. and how/why does the effect of the resistance have such a huge impact on the value of Q?
b.1 Does the incusion of the...
I have a single machine connected to an infinite bus with the following parameters:
- Sending end power = 3.75MW
- RL=5.18 ohms
- XL=130 ohms
- VS (Generator bus)=161kV
- VR (Infinite bus)=161kV
- Sending end voltage angle (delta) = 0.01877 (Angle which allows 3.75MW to be transferred)...
I'm trying to understand a 3 phase induction machine model used as a generator in a Doubly Fed Induction Generator (DFIG) arrangement in Simulink.
In this model for the induction generator component, they have stated that the model is a "Positive sequence model" of the induction generator...
So i just finished my bachelors last year in electrical engineering with honours. However, I have been thinking about it for a while and my real passion is for a career in physics. Would I be able to sign up for a post grad physics course in USA/Canada or in Australia?
Thanks
When calculating base values for current, impedance etc
do we use the line to line voltage or the phase voltage?
What's the reason for using one over the other?
