چکیده
Abstract Due to complex operation of microgrid and the difficulty extracting thin fault signal features, traditional relay protection will take misoperation protect. This article proposes a detection method based on VMD-MPE accurate detection. scheme processes current through VMD algorithm that decomposes it different modes. Considering MPE has advantage exploring dynamic mutation within faint signal, most significant mode is being computed, which can be selected extract construct feature observe difference phase, so as characterize types. Finally, model system built PSCAD simulation experiment platform for analysis experiments. The experimental results show achieve in operating states microgrid, regardless resistance points, even maintain well accuracy situations such multiple disturbances high impedance faults.

Fault Detection in Ring Based Smart LVDC Microgrid Using Ensemble of Decision Tree
In modern infrastructure, the demand for DC power-based appliances is rapidly increasing, and this phenomenon has created a positive impact on the acceptance of the DC microgrid. However, due to numerous issues such as the absence of zero crossing, bidirectional behaviour of sources, and different magnitudes of fault current during grid connected and islanded modes of operation, protecting DC m...
متن کاملUAV attitude Sensor Fault Detection Based On Fuzzy Logic and by Neural Network Model Identification
Fault detection has always been important in aviation systems to prevent many accidents. This process is possible in different ways. In this paper, we first identify the longitudinal axis plane model using neural network approach. Then based on the obtained model and using fuzzy logic, the aircraft status sensor fault detection unit was designed. The simulation results show that the fault detec...
متن کاملFault Identification in Fuel Cells Based on Bayesian Network Diagnosis
This paper considers the effects of different types of faults on a model of a proton exchange membrane fuel cell (PEMFC). Using databases (which record the effects of the faults) and probabilistic methods (such as the Bayesian-Score and Markov Chain Monte Carlo), a graphical-probabilistic model for fault diagnosis is constructed. The graphical structure defines the cause-effect relationship amo...
