Novel electric generation schemes for wind power plants, ACCG and DOIG, Part I: executive summary
Technical Report
·
OSTI ID:6943986
Two novel electric generation schemes for wind power plants are evaluated: an A.C. Commutator Generator (ACCG) and the Rotor Fed Induction Generator. The report presents experimental and analytical results and conclusions which include technical information and cost data. ACCG is a machine similar to the d.c. machine and has similar performance characteristics. Although there are no limitations on the use of this machine for wind power generation, the cost coupled with lack of a U.S. manufacturer severely limits its potential for use in variable speed contact frequency generation. Research on the Rotor Fed Induction Generator led to a power electronic circuit connected to the rotor circuit which operates as a generator with broad power vs. speed characteristics. This is applicable to wind energy systems in which speed variation is about 30-40 percent. This system can also regenerate power that would be dissipated. By this means, power output is obtained from both reactor and rotor. The machine thus devised is called a Double Output Induction Generator (DOIG). DOIG is the best choice for wind energy systems. A chart compares variable speed constant frequency generators.
