Integrating large amounts of wind power into power systems brings a large influence on the dynamic frequency response characteristic (DFRC). The traditional low-order system frequency response (SFR) model is no longer applicable at the current time. Based on the small signal analysis theory, a set of novel low-order SFR models for doubly-fed induction(More)
Sensors are critical for the monitoring and real-time control of fuel cell system, according to the reliability requirements of multi-sensor of 60kW automotive fuel cell system designed by our group, a two-level neural networks based fault diagnosis method is put forward in this paper. The two-level neural networks include a main net and five sub nets which(More)
Glycan-protein interactions play important biological roles in biological processes. Although there are some methods such as glycan arrays that may elucidate recognition events between carbohydrates and protein as well as screen the important glycan-binding proteins, there is a lack of simple effectively separate method to purify them from complex samples.(More)
In order to enhance the reliability and safety of Fuel Cell Engine(FCE),combined the composition of FCE developed by our group with the electrochemical reaction mechanism of fuel cell, the fault symptom of fuel cell stack malfunction was defined and analyzed from four aspects: hardware faults, software faults, environmental and man-made factors. Then its(More)
