关于DFIG的低压穿越能力的研究。对以后实现低压穿越做一些探索性的工作(Along with the sharp increase in the proportion of wind power supply some areas the impact of Large-scale wind farms for the stability of regional power grid is more significant. The research on low voltage ride-through (LVRT) of wind power system based on doubly-fed induction generators (DFIG) becomes a hot issue. In this paper ,Firstly introduces the concept of low voltage ride-through technology, The standards of LVRT of some European countries are presented, And then analyses and compares the kinds of common realize low voltage ride- technology and improve control strategy. The transient characteristics of DFIG when the grid voltage sagging.)

OLED DISPLAY MODULE I m using a 160x128 Graphic OLED Display from Densitron (DD-160128FC-2A) with the ATmega1281. The LCD is controlled via a SEPS525 OLED Driver IC. I use the LCD in 8bit parallel mode.  Both the LCD and controller datasheet is VERY vague and I struggle to get the LCD to respond. The OLED controller is configured via 3 registers, IR (Index), WDR (Write Data Register) & RDR (Read Data Register).  It is the first time I come across this register INDEXING method and can t find any examples or discussions on the control sequence.
