power factor controller
need to make up the Power Factor Controller for the final year project. Actually that's my friend project. He got around 6 months to compete that project, but he couldn't with group of 4 people, they had done nothing in the project so far. Now their group leader is asking me to complete his project. I believe his knowledge of electronic is poor, but on the other hand he has the highest grades achieved so far in graduation. I'll be free on 16th May 08 and their submission is on 19th May 08. I don't have enough time to carry up the research work on this. Friend of mine told me that somebody advises him to use a small matrix of capacitor on the line load and with help of relays switch them. Measure up the voltage and current phase difference and calculate the offset, according to the offset values switch capacitors accordingly with microcontroller or something.He told me he'll use the Current transformer for that. The load would be made by the autotransformer, those guys purchased the autotransformer working from line frequency. He said, it's kind of dummy inductive load for that. In short, the purpose is that when the inductive load on the line increases, the capacitors get connected on the line with relays.He also said they'll also have a zero cross detector.
I appreciate if anybody could help me as how to implement it in the block form. I'll make the circuit for that or if you have any circuit schematic on that, that would be very helpful. It's not my work so I'm not worried.Neither I care whether this final year project will be completed within 2-3 days or not! I'll try my best to make up their project.
