(To meet the power failure to keep their wind turbine grid-connected uninterruptible power supply to the system requirements, proposed doubly-fed wind turbine dynamic models of converter model, inverter protection and network model to Study of double-fed wind generator transient characteristics. to 1.5 MW SUT-1500 double-fed wind turbine prototypes, by an infinite power grid equivalent model of converter model uses the stator flux orientation of current vector control methods, using PSCAD software to double-fed motor simulation of transient characteristics. The simulation results show that vector control can be achieved double-fed motor active and reactive decoupling, and can improve the system through the capacity of low-voltage.)

classifier_D
使用SVM分类器来预测乳腺癌病人的预后(特征选择；分类器构建)，评价模型时使用无被交叉验证，性能评价指标包括准确率，AUC，灵敏度，特异度。学会最基本的机器学习方法。可查看分发给大家的代码，以后遇到类似的问题，可用相似的思路和代码。(The SVM classifier was used to predict the prognosis of breast cancer patients (feature selection; classifier construction), and the model was used without cross-validation. Performance evaluation indicators included accuracy, AUC, sensitivity, and specificity. Learn the most basic machine learning methods. You can view the code distributed to everyone, and later encounter similar problems, similar ideas and code can be used.)
