Research on VFTO Identification of GIS Based on Wavelet Transform and Singular Value Decomposition
The accurate identification of Very Fast Transient Overvoltage (VFTO) is the key of overvoltage control in modern smart grids. In order to accurately identify VFTO generated by the operation of a disconnector in Gas Insulated Substation (GIS), a VFTO ...

The content of functional ingredient fluctuated in E. mollis leaf. The functional ingredients biosynthesis pathways were revealed. EmNAC014 and EmMYB15 played key roles in functional ingredients biosynthesis. ABSTRACT Elaeagnus mollis Diels is a newly developed woody oil crop, and the biosynthesis and regulatory mechanism underlying functional and ...

Busbar Fault Direction Identification Using Sequences of Displacement Vectors
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

Modelling of Secondary Arc Using EMTP-RV [PDF]
Most of faults occurred in transmission lines are single-phase to ground faults and transient faults. Single-phase auto reclosing is an appropriate scheme to maintain the system stability and restore the system effectively when those faults are occurred.

Standard and proposed non‐standard OCR characteristics. ABSTRACT This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed scheme classifies grid operating ...
