| Abstract [eng] |
The aim of this work is to examine the influence of wind power plants, blade pitch angle control to be more accurate, on power balancing in the electrical system, examining both the possibilities of contributing to the provision of missing power and to down-balancing when excess power is generated in the network. In this paper, one of the tasks I set is to examine the possibilities of balancing the electrical system with wind power plants, also to make an overview of different types of wind power generators. The methods of system balancing in wind farms will be reviewed, as well as a comparison of different types of generators used in wind farms. Another topic that I examine in this paper is the theoretical possibilities of the pitch angle control in wind power plants to maintain the power balance of the system and also the use of PI and PID controllers in them. When the demand for power in the system increases, the wind turbines can start spinning a little faster by controlling the pitch angle of their blades, thus making it easier for the wind to spin the blades. Also, the pitch angle control can be used to maintain the power generated by wind farms at the highest point. Among other things, it can also be used for balancing down when excess power is generated and all energy storages are fully charged. The work also compares the similarities, differences, and principles of operation of PI and PID controllers. The project part simulates an offshore wind farm with the pitch angle control option in the MATLAB Simulink software package. This paper investigates the extent to which the generated power can be changed at different wind speeds and blade angles in a simulated wind farm. At the end of the work, I present the conclusions and a summary of the entire work, the obtained result. |
