Evaluating method for simulation performance of wind turbine simulator

Abstract

The invention discloses an evaluating method for simulation performance of a wind turbine simulator, and particularly relates to an evaluating method for verifying whether the wind turbine simulator can simulate a real wind turbine accurately or not. Whether the wind turbine simulates static-state characteristic of the real wind turbine accurately or not is verified through comparing steady state CP with CP max at constant wind speeds of different wind speeds, parameters of mechanical dynamic and electrical dynamic in results of a test and simulation are compared through conducting a moving die test and the simulation to the same wind turbines under same turbulent wind speed sequence, whether the turbine simulator can simulate dynamic characteristic of the real turbine accurately or not is determined, and whether design of the turbine simulator is successful or not is measured through synthesizing simulated conditions of the turbine simulator to the static-state characteristic and the dynamic characteristic of the real wind turbine. The evaluating method for the simulation performance of the wind turbine simulator solves the problem that the simulation performance of the wind turbine simulator is uneven caused by lack of a systematic performance evaluating method of the wind turbine simulator, and contributes to enhancing accuracy and practicability of simulation of the wind turbine simulator.

Description

technical field [0001] The invention belongs to the field of wind turbine simulators, in particular to a simulation performance evaluation method of a wind turbine simulator. Background technique [0002] In order to better study the static response and transient response of the wind power system under various working conditions, it is not enough to verify only by simulation. It must be combined with hardware to prove the reliability of the control strategy and the entire system. However, it is unrealistic to carry out experimental verification in the actual wind field for laboratory conditions, because the actual wind field has high construction costs, long cycle time, and quite high requirements on the surrounding environment, which cannot be provided under laboratory conditions. In order to conduct experimental research and verification of wind power system, it is very necessary to replace the actual wind power system with a wind power simulation system. The wind turbine...

AI Technical Summary

Problems solved by technology

However, in the current literature on wind turbine simulators, when verifying the wind turbine simulator, the curve of parameters such as power or torque is compared with the trend of the simulated curve, and the lack of quantitative comparison is rough and limited.

This will lead to the inability to accurately evaluate whether the designed wind turbine simulator is accurate, thereby affecting the fan simulation experiment and designing the actual wind turbine, and better simulating the static and transient characteristics of the wind turbine at different wind speeds
