29 January 2009 - 04:32 PM

Pls help me!!!

I want to use PIC to check short or open circuit. Anyone can help me? The document, book or the code (ASM, C,...), which wrote about this subject. rolleyes.gif rolleyes.gif

I don't know much about microcontroller. So it took me much time but now i also have no idea for this problem. tongue.gif tongue.gif

I only do it for fun and increase my knowledge. Pls help me

Magnetizing Losses By Star-dyn Connect In Dfig

01 May 2008 - 06:18 PM

In Induction Generator Double Fed(DFIG), stator connect Dyn when wind speed (speed of prime mover) is high; stator connect Star when wind speed (speed of prime mover) is low. This reduce flux level and magnetizing losses. Why?

How Does Dfig Operate? How Does It Start? Help Me

02 March 2008 - 03:33 AM

I don't understand the operated principle of DFIG (induction generator double-fed). Can anyone help me understand : "when DFIG starts, where does DFIG receive electric energy from? (from grid(stator) or from converter)" because when DFIG starts, stator directly connected to grid, rotor also connected to grid via converter while speed below synchronous.
Help me!
