Abstract

The generator uses a permanent magnet so it does not require initial excitation to generate a voltage. The generator design is axial flux type, uses ceramic type permanent magnet (NdFeB), uses two flanking stator rotors. For electricity use, the AC voltage is changed to DC voltage using a rectifier for charging the accumulator. The air gap in the axial generator is the distance between the rotor and the stator. The air gap is also a place for the transfer of the magnetic field through the coil on the stator to produce a magnetic flux value that affects the induced voltage in the coil. The faster the rotation, the greater the voltage generated. This axial generator that has been designed can produce a frequency of ± 50 Hz, an effective voltage of ± 22 V when the air gap is 2 mm, the frequency measurement has an error of 10-20 Hz and an error percentage of 5-10%, with the results of measuring the induced current that has a large the same voltage.

Abstract

Voltage testing, on hybrid power plants (PLTH), uses two sources that are solar/solar power plants and waterwheel power plants. Supporting components to produce electric energy conversion one of them is boostconverter which is the main subject. Therefore the author is interested in making and testing the voltage, on the boost converter with the aim to maximize the performance of the DC Genertator as a pensupplay Batterai/accu on PLTH Pico Hydro. The DC-voltage source of the DC-DC converter can be obtained from a generator, or an AC voltage source that is air-conditioned to DC. While Dc-DC converter is a power electronic circuit, to convert a DC to DC voltage input into the output voltage with a greater value. The test results of the voltage from the field data can be concluded as follows. The voltage boost converter test results, on the Pico Hydro Hybrid power plant can produce a voltage of 13 volts from the output DC Generator 8.39 Volt. The output voltage generated by the boost converter is 13.4 volts, can be stable although the output voltage of the generator is variable. With the addition of the tool boost converter on PLTH Pico Hydro, can help battery charging/ACCU to charge the required voltage of the battery is 12 volts, from the boos convevter 13.4 volt long time charging ACCU 5.3 hours.

Abstract

One effort to overcome the energy crisis is to utilize wind energy as a power source. Angina power Plant is a method for generating electrical energy by rotating the angina turbine connected with the generator, the electric energy produced by the generator is stored in an element of electric energy storage (battery). The next one will be channeled to load center like household. The Perarancangan of the horizontal type flat Multiblade Sudu is using a microcontroller that can change the angle of the sudu according to the wind speed so as to maximize the power of wind potential energy. For a sudu angle setting that can adjust the speed of the wind, use two servo motors that have been control by the Arduinouno from the input anemometer so that the angle of the sudu can adjust the wind speed. The results have shown that the turbine-angle arrangement of the turbines can increase the rotation of the wind turbine, thereby increasing the voltage raised in the generator. The optimal angle of the Sudu is at a 15o angle, at a wind speed of 9.5 m/s, resulting in a turbine round of 610 rpm.
