Electrical distribution system is the final stage in the supply of electric energy to consumers. A serious problem faced in power distribution today is due to the major losses accompanying electricity distribution. As a result utilities in the power sector are currently focusing on its reduction in order to be more competitive, since the electricity prices in deregulated markets are affected by the...
This paper describes the fuzzy logic control of motion control of mobile robot on rough terrain. The controller employed for this purpose is a two output and single output system. The input to the controller are slope of the terrain and terrain type. The output from the controller is the speed commands for the driving wheels. The controller is designed in Matlab. We have simulated the control process.
The objective of this paper is to develop a Model Predictive Control (MPC) for a Shell and Tube Heat Exchanger. Since the heat exchanger is a highly non linear system, the operating zone of the system is divided into different zones. For each zone, a model is developed. Even though PID controllers are widely used for the control of heat exchangers, there is still a need for optimizing and conservation...
In this paper, the current Harmonics in the 12-Pulse uncontrolled AC/DC converter fed AC Drives was studied. The 12-pulse Δ-Y type AC/DC converter will keep a balanced voltage with 30° phase shifted at the low coupling coefficient condition. Different converter arrangements for 12-pulse-based rectification are also studied and a novel harmonic mitigator capable of suppressing fifth, seventh, and 11...
Automotive companies have turned their concentration towards the fuel cell powered hybrid vehicle research, since it offers reduced emission and also saves our nature. The fuel economy is also considerably improved due to the plenty of source availability. The core technology behind such development of fuel cell for automotive applications is the “Power electronics”. The Power electronics influence...
This paper investigates typical behaviors like damped oscillations in fractional order (FO) dynamical systems. Such response occurs due to the presence of, what is conceived as, pseudo-damping and meta-damping in some special class of FO systems. Here, approximation of such damped oscillation in FO systems with the conventional notion of integer order damping and time constant has been carried out...
Conical tank level process was studied experimentally to obtain the process model. The linear portion of this non linear model was considered and different control schemes such as discrete time Proportional Integral Derivative control (DTPID) and Discrete time Model Predictive Control (MPC) were implemented in MATLAB environment. Among these two control schemes, MPC resulted with minimum rise time,...
Deregulation is a new paradigm in the electric power industry. In deregulated environment, the transmission Congestion Management (CM) is one of the critical and important tasks of the System Operator (SO). This paper examines the congestion relief procedure and compares the results of two different objectives i.e. rescheduling cost minimization and real power loss minimization. The above two objectives...
In this paper, the operation of a Fuzzy Logic Controller with PSS controller is analysed in simulink environment. The development of a Fuzzy Controller with power system stabilizer in order to maintain stability and enhance the performance of a power system is described widely. The application of the Fuzzy Controller with PSS controller is investigated by means of simulation studies on a single machine...
This paper presents an approach for the determination of the optimal parameters and placement of UPFC as the major concern is to ensure the full potential of utilization in the transmission network. Voltage source model is utilized to study the behaviour of the UPFC in regulating the active, reactive power and voltage profile. This model is incorporated in Newton Raphson algorithm for load flow studies...
