Hybrid systems are becoming popular for remote area power generation applications. Any effort to decrease capital and operating costs, contributes to increase penetration of hybrid systems in power generation systems. In this paper combining of hybrid systems and Thermal Energy Storage (TES) has been proposed for lowering the costs of hybrid systems in hot climate. Since nowadays TES is known as an...
Growth of electrical energy consumptions and increasing non-linear loads in power systems force the electrical power utilities to provide a high quality electrical power. This is the reason that this issue is getting more and more importance in power systems. This paper examines all power quality parameters based on the standard. In order to enhance the power quality, these parameters must be improved;...
In this paper control system of a linear permanent magnet synchronous motor is designed and modeled. This system uses both traditional controller (PID) and fuzzy logic controller (FLC) and their performances are compared. Disadvantages of PID controller are uncertainty of load fluctuations, system parameters variation, undesirable rise time, settling time and large steady-state error. On contrary...
In the design of switched reluctance motor (SRM) and its drive, analysis and simulation of the dynamic behavior of the motor is essential. In the simulation process, model of the SRM and its controller is taken into account. In this paper motor characteristics are examined and effects of the motor design parameters, such as inductance, resistance and supply voltage, on the system response is studied...
The primary role of an automatic voltage regulator (AVR) is to regulate the reactive power and voltage magnitude. The system modeled consists of the amplifier, exciter, sensor and stabilizer or proportional-integral-derivative (PID) controller. The state-space technique is used to model the system. Their characteristics and behavior are also briefly discussed. Results of the simulation studies on...
