It also proposes solutions for the integration of high-resistance grounding (HRG) in the distribution system design of various indus-tries to increase the reliability and safety of these systems.
To address this problem, a new method of distribution network fault diagnosis is proposed based on Gramian Angular Field (GAF) and Improved Convolutional Neural Networks (ICNN) in this
Abstract To enhance the reliability of ground fault detection in distribution networks and their ability to adapt to complex operating environments, this paper proposes an optimized method
The concept is a simple one: provide a path for ground current via a resistance that limits the current magnitude, and monitor to determine when an abnormal condition exists. This provides for maximum
To verify the effectiveness of the proposed method, simulations are conducted. The results demonstrate that this method can effectively handle high-resistance grounding faults under
The detection and selection technology of arc high resistance grounding faults has always been a hot research topic for experts and scholars at home and abroad.
Aiming at the problem that the traditional zero-sequence current protection cannot operate reliably when a single-phase high-resistance grounding fault occurs in a flexible grounding system, this paper
Abstract The detection and selection of fault lines in resonant grounding distribution networks pose challenges due to the lack of sufficient state
An Arc Grounding Fault Detection Method in Distribution Networks Using Chaotic DC Waveform Recognition Published in: IEEE Transactions on Instrumentation and Measurement ( Volume: 74 )
The invention utilizes discrete wavelet transform to process fault signals, and inputs the fault signals into an evolved neural network so as to detect the high-resistance grounding fault of...
High-impedance faults (HIFs) occur frequently in resonant grounding systems and are difficult to detect. Thus, an effective HIF feeder identification technology is urgently needed. This
Detecting high resistance grounding faults in distribution networks with neutral grounding via Peterson coils is challenging due to various factors, including the weak fault current magnitude, intermittent arc
These two methods are combined to form a comprehensive detection method for high resistance grounding faults, which shortens the starting time of high resistance fault criteria and
When the single-phase high resistance grounding occurs in the distribution network, the identification of fault lines is particularly difficult due to the weak fault characteristics. Therefore, A novel method for
First, we review and compare medium-voltage distribution-system grounding methods. Next, we describe directional elements suitable to provide ground fault protection in solidly- and low
GROUNDING METHODS OF MEDIUM-VOLTAGE DISTRIBUTION NETWORKS The main goals of system grounding are to minimize voltage and thermal stresses on equipment, provide personnel
