Please suggest me a recent topic in power electronics/ power system.?

Question

Have to handle a presentation on a latest trend in any of the above topic. Any reference source shall also be gratefully welome..

Answer 1

series and parallel operation of tyristors:

                                                                   for some scr with the voltage of !0kv and 3kA are avialablehowever for some industrial aplications the demand for current ratings is so high that a single SCR cannot fulfil such requirments.in such cases the SCR are conected in series in order to meet the HV demandand

Answer 2

Sugar producing nations using combined heating and power gas turbines (CHP GT's) for bio-ethanol production to produce efficient sustainable power to developing nations .

This area has had a once over in some science mags, I work with gas turbines.

It is very efficient as they can ferment the biomass of the sugar canes into ethanol, with the heat being provided by the gas turbine for the fermentation process. This is a closed loop, as the ethanol is used to run the gas turbine. The electricity can then be used for farming and refining the sugar with a lot of excess that is sold local to the local grid.

The CHP GT's can reach an efficiency of 80% and the fuel is entirely renewable and is close to the generator, further increasing the efficiency through minimal transportation costs for the fuel.

Using wet low-nox could also produce nitrates rich water for fertilizing the fields (this is a guess/suggestion at this point, do some research, I don't know if this actually occurs)

Good luck.

And if you ever think about setting these up let me know. (I will add you as a friend here so that you can contact me.)
