This paper explains a method to calculate the capacitance value of a 3-Ø cage induction motor working as a generator in the self-excited mode of operation. The synchronous impedance test method has been reviewed. The capacitance value is determined from the manufacturer data. The effect of voltage variation with different capacitances has been evaluated at constant speed. Performance of self-excited...
This paper is a contribution to the development of a real time simulator conceived for the study of the marine current energy conversion. We presented the structure of a real time marine current turbine simulator based on "hardware-in the-loop" (HILS) simulation techniques. The main components of this physical simulator are: an electromechanical sub-system (ES) and an informatics sub-system...
It is expected that increasing amounts of new generation technologies will be connected to electrical power systems in the near future. Most of these technologies are of considerably smaller scale than conventional synchronous generators and are therefore connected to distribution grids, as the DFIG-based wind farm. When connected in small amounts, the impact of wind farm on power system transient...
Distributed generation is regarded as the developing direction of the power system in 21 century. Because distributed generation always connects with the distribution system, which has great influence on every aspects of power system. This paper studied the influence of distributed generation on load modeling. When the influence of distributed generation is not negligible, the composite induction...
