AI Technical Summary

Technical Problem

In existing wind turbine control systems, foreign PLC brands are expensive and have long delivery cycles, which slows down the progress of localization. At the same time, the response lag of the pitch and yaw systems affects the safety and stability of the unit, and existing simulation methods cannot be used to verify the actual wind resources and unit components.

Method used

The simulation platform uses a domestically produced Ruiwo PLC as its main controller. By acquiring historical operating data of the wind turbine, the system transmits the data to the main PLC system of the simulation platform, calculates and issues action commands to the pitch and yaw systems, and corrects the error rate to optimize the controller design.

Benefits of technology

It improved the stability of the core controller of the wind turbine, shortened the development cycle, reduced costs, and systematically optimized the control strategy, ensuring the safety and power generation performance of the unit.

Abstract

The application provides a wind turbine semi-physical simulation method and device, which comprises the following steps: transmitting the obtained historical operation data of the wind turbine to a simulation platform master PLC system; the simulation platform master PLC system gives the variable pitch system and the yaw system action instructions according to the received historical operation data; the variable pitch system and the yaw system respectively execute corresponding experimental actions according to the received action instructions, and feed back the corresponding experimental actions to the simulation platform master PLC system; the simulation master PLC system compares the received experimental actions with the actual field instructions in the historical operation data, and obtains an error rate; and the action instructions sent by the simulation platform master PLC system are corrected according to the error rate. The method can improve the stability of the core controller of the wind turbine, shorten the development cycle, reduce the development cost, comprehensively and systematically evaluate the control strategy and optimize the control algorithm, and guarantee the safety of the unit and improve the power generation performance of the unit.
