The load terminal voltage at the low voltage side of the distribution network will drop when the user load increases. Thereby affecting the normal operation of the electrical appliance. Currently, the treatment approach to the voltage deviation at the ...

The shunt active power filter (SAPF) based on three-leg voltage source converter is widely used to compensate the harmonic currents caused by nonlinear loads of grid. However, when the nonlinear loads are unbalanced, the grid currents compensated by ...

The Thevenin equivalent parameters seen at the point of common coupling (PCC) is an important parameter for power system planning and operation, voltage stability. This paper presents a novel algorithm of tracking the power system equivalent parameters ...

According to the structure and working principle of metal-oxide surge arrester (OMA) intelligent monitoring device (IMD), this paper analyses the electromagnetic environment of it and obtains the importance and necessity of studying electromagnetic ...

High-voltage transmission towers, as support points for overhead transmission lines, are very sensitive to slope deformation, and extreme weather conditions such as heavy snow and hail can cause large changes in their internal stress distribution. It is ...

Based on techniques of time-domain index feature extraction and principal component analysis (PCA), a method for unbalanced fault diagnosis is proposed in this paper. Five dimensionless factors corresponding to IMF are calculated after the original data ...

A material charging system is a critical process in a blast furnace. Raw materials are transported from the stock house to the top of furnace and distributed into the furnace. To put defined amounts of materials into the preset position, the control and ...

An accurate refractive index of the surrounding medium is required to measure the accurate depth of the specimen in digital holographic microscopy (DHM). Many researchers have reported a method that uses blood smear to avoid overlapping of red blood ...

Health care has changed profoundly thanks to the continuous improvement of electronic devices, recent rapid progress in wireless communications and microsystems has allowed the opportunity to automatically collect reliable patient data, yet ...

In this paper, we propose a photon-counting double random phase encryption with merging reconstruction. Double random phase encryption (DRPE) is a simple and secure optical encryption technique using phase random masks. To enhance the security level, a ...

When Information System is developed a priority of subsystems development needs to be set. This problem is a more general problem than a well known problem Feedback Arc Set, and is like that problem also computationally hard to solve. Therefore in this ...

IA prototype drying system for coffee grains was developed using an oven with a feedback control system to accomplish this task. The coffee grains enter the system wet and are then subjected to a stable temperature of 45°C, thus achieving uniform ...

In the deep formation of an oil field in the east of China, due to the great change of lithology and the poor drillability of rock, the mechanical drilling rate is low, the bit footage is reduced and the drill bit is seriously worn. The prolongation of ...

In the paper a new approach for analysis of Gm-C filters is presented that is suitable for automation of some engineering tasks and integration in CAD tools. The proposed methodology includes data gathering through simulation and circuit mathematical ...
