Abstract

The total energy consumption in this year increase significantly. Most of energy that used come from fossil fuel. The use of fossil fuel can cause a lot of pollution and the amount of them is decreased. Therefore, many countries developing renewable energy system. One of renewable energy system is wind power using Doubly Fed Induction Generator (DFIG). DFIG supplies AC current from the stator winding that are connected directly to the grid and rotor winding DFIG are also connected to the grid through power electronic converter. The type of this converter is back-to-back converter. In general, this converter used switching model. However, this model produce a slow simulation and high riplle. To solve this problem DFIG with average model in back-to-back converter is studied in this research. This design operated by controlling the rotor speed DFIG to produce maximum power and preserve the value of DC link voltage remains constant.

Abstract

This paper presents a reconfiguration methodology based on a fuzzy multi-objective approach for achieving the minimum active power loss and the maximum voltage magnitude of radial distribution networks with distributed generations in order to improve the distribution system efficiency. Multi-objective function are considered for load balancing among the feeders, minimization of the real power loss, and deviation of bus voltage, while subject to a radial network structure in which all loads must be energized. These objective functions are modeled with fuzzy sets to evaluate the imprecise nature of each objective. Originality of the research is that the fuzzy-based multi-objective optimization in reconfiguration of distribution network including the distributed generation. The implementation of the fuzzy multi-objective for distribution reconfiguration on a 77 bus distribution network with distributed generation is described. The simulation results show that a 1.80% of electric power distribution network efficiency improvement is achieved by the method

Abstract

Induction motor is suitable for the prime mover of the electric vehicle since the design the electric vehicle required extra slim and compact design. Therefore, this research proposes an axial flux induction motor consists of thinstator and rotor. This research will explain about the mechanical, electrical design and implementation of the axial fluxinduction motor that consists of single stator and single rotor. Basically, the design of this machine is similar to conventionalelectric motor. The differences are on the direction of the flux and its construction. The proposed motor has 500 W inputpower, low carbon material of core and the input voltage for this motor is 100 V. Material of the motor core is made fromsteel sheet st.37. The length of axial motor is 66 mm and diameter is 200 mm. From experimental results with the inputvoltage of 15 V, the rotor is able to rotate until 1366 RPM. In order to analysis the performance of the motor, simulationmodel based experimental data of the motor is required. The curve characteristic of the motor shows that the maximumtorque of the motor is 0.79 Nm.

Abstract

Photovoltaic system that connected to grid is a system which applied for an area that can be reach by transmission line. This system as a support for conventional generating system. If there is a power from PV system, then power demand supplied from photovoltaic generating system. Otherwise, power demand supplied from conventional generating system. As a support conventional generating system, there is many methods to convert photo energy into AC system that connected to grid. One of conventional methods as a two stage inverter, this methods need two process to convert photovoltaic into AC system. First stage, conversion photovoltaic power to DC system. In this stage PV processed by buck boost converter. Second stage, that DC power from first stage changed into AC power system. This two stage process has low efficiency, so we try to make the process simply and more efficiency. New method called single stage inverter can be applied. With this methods, conversion DC power system from PV can be done by single stage process. From this single process, we expext that more efficiency can be achieved.
