This Project presents electric bicycle. The structural feature is the use of the bicycle to be modified as it is designed to spin the rotor of the 5-phase magnetic line generator set and test the voltage distribution. The principle of operation of electric bicycles relies on the mechanical energy gained from cycling. The rotor consists of a series of permanent magnetic poles intersecting with a stator consisting of a set of conductor coils generating an AC voltage and converting it from AC to DC through a diode bridge to obtain DC voltage. To be connected to the boost converter to increase the output side pressure level to get the right voltage to charge a 12 volt battery. batteries. The test has been tested for cycling to generate electricity at a speed of 400 rpm while no-load has a voltage of 23.3 volt and with a load per load and at a speed of 400 rpm the voltage is 12.1 volt If the bicycle is cycled at an increased speed the voltage and current will increase. In order to transmit electric power to the single-phase power system an inverter is used to connect the single-phase power system to transmit to the single-phase power grid.

This research had the objective to design and develop power production from daily life leftovers for their highest benefit of utilization by using the principle of quality function development and power generator that changed mechanical energy into electric energy. In developing electric generator product from air conditioner condensing unit the researcher found that there were 4 important factors including speed installation distance size and cross-sectional area of the fan and the test was conducted between 8.00-17.00 hours. The researcher collected the data and analyzed the test result and found that the best result in the test was to install the product at the distance of 10 cm by using an 18 fan in order to acquire the best voltage and the data were collected so that they could be implemented in developing such product in the future.

This research presents the simulation of a three-phase generator. The aim is to study and analyze the condition of the generator functions. By simulating the operation of the generator used in factory which use this generator as a backup power source to replace primary power source of electricity-supplier. In this test can start or stop the generator to determine the parameters at that time. The generator is used when the main electrical power distribution error and the generator is disabled when electric power system of electricity-supplier back to normal.

This research study is the economic load dispatch ELD is the method of determining the most efficient low-cost and reliable operation of a power system by dispatching the available electricity generation resources to supply the load on the system. The main objective of ELD is to schedule the committed generating units output to meet the required load demand at minimum cost satisfying all unit and system operational constraints. With the proper scheduled outputs of generating units it can lead to a significant cost saving of generating systems. This paper presents an optimization technique to economic load dispatch (ELD) problems with considering the daily load patterns and generator constraints using a particle swarm optimization (PSO). The objective is to minimize the fuel cost. The optimization problem is subject to system constraints consisting of power balance and generation output of each units. The application of a constriction factor into PSO is a useful strategy to ensure convergence of the particle swarm algorithm. The proposed method is able to determine the output power generation for all of the power generation units so that the total constraint cost function is minimized. The performance of the developed methodology is demonstrated by case studies in test system of fifteen-generation units. The results show that the proposed algorithm gives the minimum total cost of generation while satisfying all the constraints and benefiting greatly from saving in power loss reduction.

This thesis is duplicated of the controlled of the AC. Three Phase Generator with case study and analyze of the characteristic of generator in various operating conditions. By the model works of the actual use in establishment generator this is using generator for backup electricity from main feeder. We have the functional testing of start or stop for check store the characteristics in different conditions at that time. Load distributing of generator for check store parameters. The parallelization of generator into the system in case of emergency while the failure of the mains system. The degradation of generator off the system when main is back to normal or the emergency stops of generator in case of accident during the operation.
