Abstract

Switched Reluctance Motor (SRM) suffers from current ripples and speed oscillations due to variations in loading conditions. Most of researches focus on enhancing the performance of SRM through speed and current controllers. This paper proposes two relatively new strategies to enhance the performance of the SRM. First one is optimizing the gain of classical proportional integral (PI) controller using sine-cosine optimization (SCO). The other strategy is to use adaptive PI controller. The proposed techniques are evaluated under several loading conditions with the proposed strategies applied in the current control system. The results deduced the superiority of adaptive controller under all loading conditions presented.

Abstract

The objective of the work is to design a load frequency controller for a two area Thermal-Thermal power system interconnected with a hybrid distributed generation system in area-1. A novel nature inspired meta-heuristic optimization algorithm, called Whale Optimization Algorithm (WOA) is used for obtaining the gain values of Proportional-Integral- Derivative (PID) controller. The dynamic system performance has been studied and the results obtained are compared with other techniques like Particle swarm optimization (PSO), Harmony search (HS), Flower pollination algorithm (FPA). The results demonstrate the robustness of the proposed algorithm in terms of settling time in the profile of frequency deviations. The simulation process is carried out in MATLAB R2010a environment.

Abstract

This paper presents a technique by which we will get realtime data of an induction motor and controlling its speed using PLCC (Power Line Carrier Communication). The main aim of using power line carrier communication is to utilize the already existing power cable for data transferring and communication. We can apply this system usually in small areas such as house, offices, etc., by which we can control various kinds of system remotely and this will help to make work efficiently through automation. In this project we are controlling the speed of single phase induction motor and collecting its realtime data through PLCC system. In order to control speed of induction motor, TRIAC circuitry is used.

Abstract

Present-day power system has highly complex and stressed operating condition owing to insufficient reactive power for meeting the required power demand. This increases the real power and reactive power losses and voltage instability that occurs in a power system. To attain the malleable operation of the power system, FACTS (Flexible Alternating Current Transmission System) devices have been used. Optimal location of FACTS devices influences the performance of the system and majorly affects the line/bus reactive power flows and hence with this effect, the line/bus voltage profiles has been improved and further the power losses are reduced. Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and GAPSO Hybrid methods have been used for identifying the weakest bus/branch for suitable placement of UPFC device to improve the voltage stability. More significant reduction of the power losses in a MATLAB environment have been discussed in this paper.

Abstract

This paper discusses the effects of the distribution of energy losses for different load forms in radial distribution networks. Three types of characteristic load are taken into consideration: steady energy, constant current, and steady imbalance load. On the basis of the current flowing through network branches, deficit distribution has been calculated. All fair allocation parameters are considered by the calculation algorithm. The graphs obtained define the topology of the network. Formulas are given in each branch of the network for calculation and loss distribution. It is shown that real power losses are hardly influenced by the type of load and must therefore be considered for loss allocation estimation.
