In this study, the aim is to detect an induction motor's winding faults by using independent component analysis (ICA). Many laboratory experiments have been done on an induction motor to check the performance of the proposed method. The phase currents of the induction motor are used in the fault detection algorithm. The algorithm is implemente d by using MATLAB. The proposed method is compared to...
Dynamic voltage stability has been an important problem in electric power systems. The dynamic behavior of modern power networks has been experiencing significant changes mainly due to the restructuring of electric industry, the introducing of open market environment and competition. In this paper it is presented a methodology to assess the dynamic voltage stability of an electric power system using...
This paper, which is an extended version of Referenced paper, presents a new transformer model displaying hysteresis using MATLABtrade Simulink environment. The proposed model displays a complete scheme for the simulation of three phase transformers. The new model is mainly based on transmission line model (TLM) of power system using lumped parameters. The developed model is particularly suitable...
This paper presents a novel formulation for differential protection of three-phase transformers. The discrete wavelet transform (DWT) is employed to extract transitory features of transformer three-phase differential currents to detect internal faulty conditions. The performance of the proposed algorithm is evaluated through simulation of faulty and non-faulty test cases on a power transformer using...
In this paper, practical applications of optimal and flexible controlled (OFC) active filters operating under distorted voltages with non-ideal compensator systems are investigated. In the previous works, the compensator system is regarded as an ideal inverter. On the contrary, this paper takes into account a set of important limitations of the real compensators in frequency domain. Some restrictions...
