Simulation of Automatic Control Model for Wind Power Generation System Grid Connection Based on PLC Optimization Control Algorithm

The trouble of global energy shortage is becoming increasingly severe, and environmental factors are becoming increasingly necessary for social development. Therefore, the growth and utilization of new energy has become the main research direction for future development. Wind energy is a clean and pollution-free renewable energy source, and wind power generation is beneficial for energy conservation and emission reduction. With the progress of science and technology, new energy has been widely applied, and wind power generation is one of the most proficient technologies mastered by Chinese researchers. This technology is a combination of China's abundant wind energy and supporting systems, transforming wind energy into electricity. However, there are many potential faults in large wind turbines, which require higher requirements for the control system of wind turbines. This article constructs an automatic control model for grid connection of a doubly fed wind power generation system (WPGS) based on PLC optimization control algorithm. The experimental results show that this system makes the control system more efficient, with higher safety factors, and better maintainability; Capable of real-time monitoring of unit operation status, effectively improving wind turbine power utilization hours, and improving wind farm management efficiency and level.
