This Thesis presents an analysis of wind turbines in a power distribution system that has a wind power source. By comparing the wind turbine with 3 blades and 4 wind turbines while there is no distribution in the distribution system. And the load is distributed in the distribution system To analyze the differences of these 2 wind turbines analyze the pressure values The power quality in the distribution system that occurs. And able to apply wind turbine energy for sustainability And practices to support the correct power supply In the distribution system and able to provide electricity with efficiency and reliability Wind turbine when connecting to the electricity distribution system There is a significant impact on the power distribution system such as the impact on the power loss. Pressure impact etc. It can be seen that the wind turbine with 3 blades works less than the wind turbine with 4 blades not so much. Therefore the test shows that the analysis of the electricity quality in this distribution system for use as a case study And continue to improve the production of wind turbines in the electricity distribution system.

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.

This project 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.

Thesis this has the objective for design build and test ability in the work of set propeller wind generator by divide recording is 3 period in morning noon and evening each phase 1 hour record speed wind value capacity air value and electrical resistance every 10 minute. Of the periment form wind nature source and model with electric fan. The result stud makes to know that propeller at have property that is appropriate area stet experimental at wind speed 2 – 2.5 m/s is propeller make from pipe PVC by propeller has length 1.30 m. the area in front cut a propeller 0.16 m. through a propeller the corner twists in installation propeller

Research this project invents for design and build the water turbine produce the electricity by set up the equipment produces the electric current from water energy flows from the nature which be new choice for Thailand in using energy pays back. then born the idea in energy water lead flows in the tide comes to use is born the advantage The water turbine has produced the electricity that does designing and establish to compose 3 part importance be the part of water buoy water turbine part is the pin wheel that is made of the iron each have a draught 90 centimeter group part carries round which compose the gearwheel yes carry round and a transmitting belt carry round . From pin wheel test produces the electric current that establishes to induce float in a river already record seek feeling numb fire efficiency reaches to open 12 DC good and use inverter to 220 v. AC
