| combining solar and wind energies Posted: 26 Sep 2010 06:34 AM PDT We are planning for a project, where we are combining the powers generated from solar panels and wind turbine and feeding it to the load through the grid. Power can flow in and out of the grid, so that maximum power is taken from the alternate sources, but is also backed up by the grid, in case of shortage. Also, when the power from the alternate sources exceeds the consumption, the excess power is fed into the grid, so that the meter spins backwards and the E.B. bill gets reduced. Our major project would be to tame the powers coming from both sources using a regulator, convert it into ac power using an inverter, and then feed it into the grid, before supplying it to the load. As its a very large scale project, we are planning to simulate it. Kindly give us suggestions regarding the softwares which would best suit this project. Thanks in advance! |
| Posted: 26 Sep 2010 05:31 AM PDT hi guys i am doing the experiment 'study of pll'-finding its lock range and capture range (free running frequency is 2.5khz) can anyone clearly explain me how to find fc1,fl2,fc2,fl1 any tips are great welcome |
| Posted: 26 Sep 2010 04:35 AM PDT Q1. How capaitor acts as a filter ?(reason behind its action) Q2. Why capacitors with high capacitance are used at power rails and the one with low capacitance at power dips ?? ( i am asking how to decide which capacitor should be used where ) Q3. Why capacitor blocks dc current while allows ac current to pass? i know mathematically but want to know physically |
