This paper considers the features extraction of Gas Insulated metal-enclosed switchgear(GIS) which suffer from partial discharge (PD) by floating electrode defect. The 220kV GIS bus bar cavity is taken as an object to design physical model of floating electrode defect. The experiment PD data are obtained from a 220 kV GIS equipment using Ultra-high frequency(UHF) partial discharge measurement. The...
In this paper, a 220kV GIS bus bar model is established to study partial discharge characteristics of floating electrode defect in Gas Insulated Switchgear (GIS), which is one of the common sources of PD. The 220kV GIS bus bar cavity is taken as an object to design physical model of floating electrode defect. The PD development process is researched by applying gradually increased voltage. The UHF...
Submerged arc furnace is a system with strong coupling, nonlinearity and time-variability. In this paper, a logistic-interpolation-based fuzzy controller for electrode regulation of submerged arc furnace is proposed. The proposed controller is based on fuzzy logic control strategy, and interpolation algorithm is employed to improve the control accuracy without raising complexity of the controller...
In our previous work [8] we proposed two methods to identify the reference electrode signal under the key assumption that the reference signal is independent from EEG sources. Although this assumption is shown to be possibly true for intracranial EEG with a scalp reference. However, this assumption may not be true for scalp sources with a scalp reference electrode. As such, this limits the application...
