wind turbine

This paper explores the evolution of wind power plant (WPP) control strategies, from simple approaches aimed at optimizing the operation of individual wind turbines to the development of more complex systems that manage WPPs as single integrated entities. Particular attention is paid to the key requirements for WPP control systems and the analysis of WPP structure, especially in the context of their integration into the overall power system. The main objectives of WPP control systems have been studied.

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.

The development of the national wind power industry in Ukraine faces a number of problems because of the lack of sufficient information on the peculiarities of the operating modes of wind farms under real-life conditions. This applies to wind load indices in different regions, estimates of the performance of wind power plants with different types of wind turbines.

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.
