Abstract: Turbo-expanders
are very useful equipment for energy recovery in gas pressure reduction
stations. Using these equipment for generating electrical energy has gained
more attention recently. On the other hand, turbo expander driven generators
affect the electrical networks considerably as a new type of distribution power
generation. To investigate the effects, first the turbo-expander is analyzed in
conjunction with the electrical networks and then some power quality problems
are studied in this paper. To overcome the observed problems the FACTS devices
are advised. Because of the system nonlinearity, a nonlinear fuzzy –PI
controller is used for the STATCOM control system. Finally behavior of the
system is compared in the cases with conventional and fuzzy PI controllers.
