THE reference for power system transients
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.
I have a question regarding how to use a non-linear inductance to represent the transformer mag Z when using the BCTRAN model. The BCTRAN documentation is not very clear on how to treat this situation. The documentation says that the rated excitation value should be subtracted from the non-linear inductance curve. I'm not quite sure what the author intended there. Some clarification would be greatly appreciated.
Does anyone have any experience with using EMTP for transient recovery voltage analysis? I would like to have the ability to compare the resulting voltage profile (system response) with standard capability curves from a selection in a library. Any thoughts?
I would like to know what experiences users have with developing detailed complex control systems. In particular is there a way to initialize the controls blocks other than having to specify an initial condition for each individual block? This quickly becomes impractical as the controls model becomes more comlpex. Thanks.
I am doing a TRV study on a 345 kV reactor breaker. I noticed the EMTP example splits the reactor model in two. Why is this?
