A system based on STM32F103 chip is designed to simulate the hybrid wind and PV wind power generation control process. The simulation system consists an electric motor with stepless rotational speed regulating feature to simulate wind turbine power generation, a light intensity sensor to simulate PV power generation with its measure results, the electrical source of chip microcomputer to simulate the current output from storage batteries, and two electric motors with different power to simulate the direct-current loads. The control strategy and the corresponding programs are developed based on certain hardware composition and the control system is implemented and operates well.

Power Generation Performance

Background: This paper proposes a Nautilus isometric spiral vertical axis wind turbine, which is a new structure, and its aerodynamic performance and power generation performance need to be analyzed. Methods: A 3D model of the wind turbine was built and its aerodynamic performance was analyzed. Then the wind turbine power generation and grid-connected simulation platform was built by MATLAB/SIMULINK, and its power generation performance and subsequent grid connection were studied. Results: The basic parameters of the wind turbine were obtained. In order to improve efficiency, parameters such as pressure, torque, wind energy utilization rate and relative velocity of wind turbines with different blade numbers and different sizes were compared. In addition, by building a simulation platform for the power generation control system, the power generation characteristics and grid connection characteristic curves of the generator were obtained. Conclusions: When the number of blades is three and the ratio between the ellipse major axis and minor axis of the blade inlet is 0.76, the best efficiency of the wind turbine can be obtained. Application of the power generation control system used in this paper can achieve grid-connected operation of this wind turbine. It also confirmed that the Nautilus isometric spiral wind turbine has good performance and is worthy of in-depth research.
