General Discussion

I want to obtain the admittance matrix of an external system seen from boundary ports.

Hi, I am working on FACTS controller and I need to measure spectral cotent of current/voltage signal. I have tried matlab but coulnd't achieve satisfactory result. I guess it is due to the simulation time step emtp use for transients is different than Main Time Step we supplied on simulation option. Is there any spectrum analyzer tool? Thanks

Hello,there is a question to ask you.

I would use EMTPWorks 2.02 to starting a Synchronous Motor.
But there is no initial condition settings which could let Synchronous Motor to "starting" in EMTPWorks 2.02.
I have ever seen a demo which is "Starting a Synchronous Motor" in MATLAB R2006b.
Would you tell me the method to starting motor or some tips of setting initial condition?
Or any example that it can starting the Synchronous Motor to steady state from stoped?

Thank you!!

Can you link the value of different components together, so that if you copy nad paste 50 resistors and ahcnge teh value of 1, you can change all of them? Also is there a way to use equations to link these as well for parametric studies?

After generating ZnO surge arrester using Zno Data Function we obtain a punch card which we can use for any surge arrester from a particular model and manufacturer for any rated voltage.

What value of Vref do we need to enter in order to scale the data?

For example - I produced a 96kV rated surge arrester .pun card - then wanted to convert it to a 120kV rated equivalent. The Zno Data Functionrecommends we use 2 x Vrated when generating the data - ie 192kV. In the ZnO model for the 120kV rated equivalent should I make Vref = 240kV ?

Are there any EMTP examples available on TRV?  I am specifically looking for an example that shows how to draw the older (1-cos) and exponential, as well as the newer 2 parameter and 4 parameter breaker capability curves.

we need power quality examples on distrubion systems using emtp at the different conditions. Especialy, from substations to end users.

we are looking forward to hearing from you as soon as possible.

sincerly...

Is it possible to simulate a rotor fault inside a synchronous generator ?

Thank you !

My question regards what are the possible roads to simulate a system of decentralizzato control of a microgrid based on the autonomous agents, using EMTP.

The control system should be such to allow the tension and frequency control when the microgrid is isolated.

It should furthermore be able to evaluate the amount of electric energy to buy from the net and the amount which must be produced by the sources (and by what sources it must be produced) on the basis of the energy and raw materials market cost, according to cheap optimum criterions.

Thanks

I am a student in electric engineering and I am preparing a thesis in which I try to realize a control system  for a microgrid based on the autonomous agents. To simulate the behaviour of the microgrid I have thought I would use EMTP.

The controller of the microgrid will be a block planned by one java script will recall the JADE platform where the acting evolving roveranno the optimum control action.

Wanted to wonder whether someone has already tried to do something of the kind, and if possible have some advice for the implementation of a system of this type.
