The squirrel-cage induction motor remains the workhorse of the petrochemical industry because of its versatility and ruggedness. However, it has its limitations, which if exceeded will cause premature failure of the stator, rotor, bearings or shaft. This paper is the final abridgement and update of six previous papers for the Petroleum and Chemical Industry Committee of the IEEE Industry Applic...

Three-phase asynchronous motors (are aslo called induction motors) are rugged, robust, and an integral part of many applications for most industries worldwide. The general type the three-phase motor, mostly used in industry, is squirrel cage. method introduced into this paper direct torque control (DTC), which utilizes characteristic a motor to produce quick robust response inverters. entire sy...

Winding function method (WFM) provides a detailed and rather simple analytical modeling and simulation technique for analyzing performance of faulty squirrel-cage induction motors (SCIMs). Such analysis is mainly applicable for designing on-line fault diagnosis techniques. In this paper, WFM is extended to include variable degree of magnetic saturation by applying an appropriate air gap functio...

As power systems become more complex and heavily loaded, voltage stability becomes an increasing serious problem. Voltage instability problems increasing day by day because of demand increase. It is very important to analyze the power system with respect to voltage stability. At present, wind power energy is increasingly penetrating electrical grids. This penetration is mainly driven by better ...
