Testing the Bayu Power Plant (PLTPB) based microcontroller AT-Mega328

Technological advances are so rapid that it demands the use of energy that continues to increase rapidly. The more advanced a country so the greater the electricity energy needed. When reviewed from today's energy sourcing source, fossil sources of energy derived from fossils are the main source. Sources of fossil energy contained on earth are very limited and at one time will be exhausted, therefore various research conducted by researchers to find energy sources outside the fossil as a source of alternative energy that can be utilized as needed. One of the sources of alternative energy that can be developed is wind power plant (PLTB). According to the National Institute of Aviation and Space (LAPAN) research, Bali Island has a potential wind of 1019 MW.

Wind speed is one of the main factors affecting the large power generated by the PLTB. The working principle of the PLTB is by utilizing the wind kinetic energy that enters into the effective area of the turbine to rotate the wind turbine, then this rotary energy is passed to the generator to generate electrical energy. The wind velocity that is muted by the turbine greatly affects the electrical energy produced. The shape and large wind turbine in a wide range of plants so that the performance of PLTB is also different, so it needs a fast and accurate testing and measurement by utilizing microcontroller technology.

Microcontroller AT-Mega328 is an AVR 8 bit family microcontroller. Some types of microcontrollers similar to this AT-Mega8 include AT-Mega8535, AT-Mega16, AT-Mega32, AT-Mega328, which distinguish between microcontrollers, among others, the size of the memory, the number of GPIO (PIN input/output), peripheral (USART, timer, counter, etc.). This microcontroller is used to perform measurements in real time and the data of these real time measurement results can be stored in the microcontroller data logger for further analyzed the electrical energy generated from the wind speed. An innovation using a microcontroller is needed to obtain data on wind energy and electrical power to analyze the performance of the PLTB tested.
