Electrical motor with high performance and maintenance free is very atteractive for the special application in the case of limited energy sources and long operating board. Permenant magnet brush DC motor is very good candidate for such specific applications. In this paper,at first a mathematical model of the motor is persented then, a method for […]
This paper presents a study about of a fuzzy Controlled STATCOM, which can be applied for mitigation of the voltage flicker in a distribution system. The voltage flicker is produced by a large variable load absorbing continuously changing currents such as an arc furnace. The DSTATCOM includes a voltage-sourced PWM inverter and its control system. […]
This paper presents a study on the four-leg VSI based distribution static compensator (D-STATCOM) for compensation of neutral, source & PCC current harmonic distortion, PCC voltage regulation and compensation of unbalanced in current waveform. This solution could be used for three-phase four-wire nonlinear and unbalanced load medium voltage distribution system. The proposed control algorithm is […]
In this paper, the Fuzzy PI controller is used to control the hydraulic servo-valves in Saba iron casting facility in Mobarakeh Steel Company. The electronic and control circuitry in the hydraulic servo-valves was damaged and the oil pressure sensor was not working anymore. The roles were bending and slabs were occasionally broken. Any replacement of […]
In this era, distributed energy resources are sustainable solution on energy crisis. Distributed generation are generating power for local loads as well as sharing it to main grid. System may get islanded after occurrence of fault. It is necessary to detect islanding earlier. Here adaptive network based fuzzy inference system is used for CEGRE LV […]
