传递熵算法在风电机组故障穿越特征分析中的应用
Characteristic Analysis of Wind Turbine Fault Ride Through Procedure Using Transfer Entropy
摘要
Abstract
In order to guarantee the authenticity and credibility of wind power grid integration simulation, it is necessary to evaluate the accuracy of wind turbine simulation model. Due to the lack of a simple and effective method for characteristic analysis and state identification, the fault transient interval cannot be clearly divided in current model validation standards. This paper tried to analyze the electric characteristics of wind turbine fault ride through procedure based on transfer entropy, which had been well applied in many research areas. Firstly, sliding time windows was used to calculate the probability density to get a temporal transfer entropy curve. Then, the validity of feature extraction of voltage and current signals had been studied, regarding the representation of grid faults and wind turbine control. Finally, the method of state identification using transfer entropy was presented. Results show that this method has features like simple criteria, low error and high versatility, and fulfills the actual demand of model validation.关键词
