Wind Turbine Performance Evaluation And Load Calculation

In this document, the author makes a research on the method of performance and loads calculations of wind turbine by computer modeling and simulations. He presents the basic methods and theories of wind turbine simulations detailedly. The author founds the model for the blade, tower, nacelle and the hub of the 750kw wind turbine, and makes the basic ways of the loads calculation, then go on the static and dynamic simulating calculations. He adopts the finite element ways to analyze and calculate the main components for that the wind turbine can work normally in the life time. All the modeling and simulations are completed by the bladed for windows software. The control parameters influenced the loads of the stall wind turbine small. But it will be bigger to the variable pitch wind turbine and the variable speed wind turbine. In this article, the author attempts to obtain the gain of Kp and Ki of the PI regulator through building the model of the wind turbine, then input the parameters to the Bladed. The results show the loads were influenced by the control system apparently. It should optimize the control parameters when we design the wind turbine.
