In order to address the issue of minor fault detection in nonlinear dynamic processes, this paper proposes a fault detection method based on generalized non‐negative matrix projection‐maximum mean discrepancy (GNMP‐MMD). Firstly, the GNMP is employed to acquire the residual scores of the samples. Subsequently, a sliding window approach is integrated with MMD for real‐time monitoring of sample status...
Flood has two cases, namely “non-source flood” and “source flood”. For each case, flood inundation analysis method based on DEM is discussed. In the paper, Kaiyuan city of the Red River state in Yunnan Province is chosen as experimental area. This region has abundant rainfall, numerous rivers and frequent flood disasters. After calculate the flood area of this region, overlay analysis is used to predict...
Harmonic pollution in modern power system is a major problem. In order to analyze the influence of harmonic caused by electric locomotive on power system, taking Ynd11 transformer connection of a traction station as a example, this paper presents a dynamic model of electric locomotive and traction power supply system, and conducts simulation analysis of the injection of 110 kV side of the imbalance...
