The dispersed generation is recently increased introduction for the energy supply rationalization and effective management of power system. But the dispersed generation causes to the various trouble that isn't occurred in the past, for example, the two way systems have an effect on the mistake action of protection equipment and the power quality. In this paper, we research the influence on the harmonic when the dispersed generation is interconnected with distribution system. To achievement, we construct the interconnecting dispersed generation and distribution system which is applied to the permission of harmonic emission. After that, we simulate about the harmonic of distribution system interconnection dispersed generation by the PSCAD/EMTDC analyzing transient state of the power system.

This paper deals with experimental verifications and the electromagnetic characteristics analysis of multi-pole permanent magnet (PM) generator for small-scaled wind power system. Field distribution due to PMs and winding current, cogging torque considering skew effect are analyzed. In addition, using the equivalent circuit method and dynamic d-q method, generating performance analysis is performed. Analysis results are validated by comparison with nonlinear finite element analyses and experimental results.

This paper deals with the electromagnetic performance evaluation of synchronous generator with outer PM rotor for small-scale wind power system. The results obtained by analytical techniques are validated by comparison with thoes by nonlinear finite element method(FEM) considering wind power turbine characteristics.

This paper deals with efficiency characteristics analysis of wind power generator with outer permanent magnet rotor according to load condition. The analyzed results are compared with experimental results, and it demonstrates the validity of the proposed analysis method. From the derived analysis results, this paper suggests the necessity of performance analysis considering load conditions for the initial design of PM generator.
