Internal winding faults resulting from the degradation of transformer winding insulation can be catastrophic and hence expensive. In the new environment of deregulation, utilities therefore are needing inexpensive methods employed to detect such faults in the incipient stage.

The development of an accurate internal fault diagnostic technique for transformers must be based on analysis of quantities from faults scenarios.

Considering the safety of personal, the damage that will occur in the transformer, the consumed time, and related c ....etc

Abstract
This paper describes a generalid simulation model of the three-phase induction motor using the SIMULIMC software package of MATLAB. The model is based on two-axis theory of revolving frame transformation. The model takes power source and load torque as inputs and gives speed and electromagnetic torque as outputs. Internal resistance of the power supply and magnetic saturation of the motor may also be accounted for.

Abstract-Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission and generation reserves, while enhancing the power system performance. Moreover, the current trend of deregulated electricity m ....etc

A multi-scale model for electrochemistry in proton exchange membrane (PEM) fuel cells has been developed. The multi-scale model involves four scales: atomic-scale for kinetics of chemical/electrochemical reaction, nano-scale for surface reactions, micro-scale for electrolyte transport, and macro-scale. The energetics of chemical and electrochemical reactions are computed using quantum computation which serves as input for the kinetics on nano-scale catalysts which is simulated using the dynamic Monte Carlo (DMC) method. A full fuel cell model w ....etc

Dear representatives.

Hi. I'm hoyun who has been studying SFCL application in DC power system from hanyang university in KOREA.

I'm wondering if i know method to design inductive sfcl (saturated iron core type and shielded type sfcl).

Would you mind teach me about design method inductive type sfcl in matlab.

I wanna apply in HVDC power system.its specification is 154kv rated voltage.

Please contact to me as soon as possible.

Thank you.

Kinds regards.
