Machine learning-based fault detection technology has gained significant attention in recent years. However, the practical implementation of such technologies often encounters challenges selecting appropriate characteristics and network parameters. This study proposes a novel method for series arc based on combined approach complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) improved fireworks algorithm-1D convolutional neural (IFWA-1DCNN). Following CEEMDAN...
The detection of series arc faults using fault current is difficult to overcome the influence load types, making it establish a unified criterion. In contrast, since voltage waveform point less affected by types and basically square wave shape, which provide conditions for constructing terms information, distortion on load-side caused transition edge provides position information edge, its polarity, amplitude rate change make possible distinguish from normal harmonic drop, theoretical basis...
Aiming at the detection and localization of arc faults in photovoltaic arrays, especially large-scale systems, this paper analyzes differences voltage current characteristics different locations under types by constructing equivalent circuit models scenarios. According to typical fault string busbar faults, a comprehensive criterion integrating use mean difference value characteristic band energy ratio is constructed for string-side detection, while are used construct busbar-side detection....
The effective identification of series arc faults is considerable significance for preventing fires in residential buildings. Series fault currents and load have a similar waveform, the features nonfault are superimposed on current signal. Fault deeply hidden, making it difficult to identify them. This work proposes method based complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) preprocessing one-dimensional convolutional neural network (1DCNN). CEEMDAN algorithm...
The degree of ablation the contact circuit breaker is one important representations life breaker. existing method cannot detect and evaluate on line. experiments in laboratory show that electromagnetic waves radiated during breaking process are related to contact. In order further clarify this association lay foundation for assessment contacts based radiation wave detection process, tests were carried out a new until end which it break short-circuit current, its signals measured. results...
It is of great importance that insulated jumper clips are used to transfer current during live-ling work on 10kV distribution lines ensure the safety live workers. To this end, a 1:1 simulation model 2756/SJ1503 clip established and temperature rise simulated using electric-thermal-force multi-physical field coupling method. The validity verified through experiments analyze effect wire clamps in terms contact pressure, ambient temperature, light intensity, wind speed, load capacity....
This paper designs a wireless data Transceiver by using nRF905, DS18B20 and STC12C5410AD. Through I/V converter,the can receive the standard 4-20mA current signals exported transmitter. So transceiver has certain universal. The furnace temperature Wireless Data Acquisition System is designed describing hardware circuit sending/ receiving flow. system low-power, low cost simple to achieve, be widely used in variety of fields.
With the continuous improvement of urbanization, cable rate urban power grid continues to rise, dense laying high-voltage cables various voltage levels in same channel increase, and requirements for safe operation are becoming higher higher. The existing detection methods can not effectively find problems handover stage time, there is a lack on-site rapid defect evaluation method, X-ray imaging technology has become first choice internal method XLPE insulated cable. Because one exposure only...
