Modeling and control of an electromechanical system with a permanent magnet generator and a voltage source converter

In the paper simulation dynamic models for the analysis of characteristics and transients of electromechanical system using a permanent magnet electric generator (PMG) connected to a variable speed fixed pitch wind turbine (WT) and a voltage source converter (VSC) mathematical models are developed. The system supplies a direct current (dc) resistive load through a controlled switch.

Basical Aspects of Integration Wind Plants in Electric System

The conditions of the point of common coupling choice of wind power plants are shown schematically and the conditions that must be met for their joint operation as a part of the power systems are described. The effects of integration of wind power plants into the power systems at the local and general levels are analyzed. The requirements of the international Grid Codes to the frequency control of the power systems with wind power plants are considered.

Changes of Voltage in Electrical Micronetwork With Hybrid Power Plant

The paper presents the study results on renewable energy hybrid system within a micro grid which is tied to bulk power system. The voltage variations character has been analyzed considering mode of wind generator reactive power control. Optimal reactive power control requirements are shown in consideration of voltage variation mitigation.

Динаміка обертального руху вітроколеса

The differential equation of wind-wheel rotational motion under the influence of aerodynamic and resistance moments was built on the basis of the simplified kinematic scheme of horizontal axis wind turbine and with the help of Lagrange second-order equations. The determination of motion parameters and the construction of appropriate time diagrams were realized taking into consideration time dependencies of wind-flow speed.
