Development of maximum power point tracking on a standalone photovoltaic power plant_Fong Kar Man_E3_2014_NI
Kuasa yang diserap oleh panel solar dipengaruhi oleh keamatan cahaya matahari, sinaran dan suhu. Oleh itu, sistem penjejakan titik kuasa maksimum (MPPT) diperkenalkan pada panel solar untuk membantu mengesan kuasa maksimum pada suhu yang tertentu, sinaran dan tahap kecondongan panel solar. Projek ini terdiri daripada dua bahagian iaitu bahagian pengesan dan penukar dc - dc. Bahagian pengesan terdiri daripada pengesan voltan, pengesan arus, pengesan suhu, mikro-pengawal dan paparan hablur cecair . Pengesan voltan yang mengandungi dua perintang dan ACS 712, pengesan arus diperlukan untuk mengesan kuasa yang dituai dari panel solar. Arduino digunakan untuk program Atmega 328-PU. Mikro-pengawal ini bertindak sebagai “otak" bagi keseluruhan litar. Ia membaca nilai-nilai pengesan dan memaparkan mereka pada paparan hablur cecair .Kaedah pengusikan dan permerhatian (P&O) dipilih dan digunakan dalam projek ini kerana ia adalah kaedah yang paling mudah berbanding dengan kaedah lain. Penukar meningkat dibina untuk bahagian kedua. Lebar denyut modulasi (PWM) dikawal mengikut kitar tugas menggunakan mikropengawal untuk mengesan kuasa maksimum. Pembandingan kecekapan antara dua sistem PV, satu dengan MPPT dan yang lain tanpa MPPT dilakukan dalam projek ini. Data bagi kedua-dua sistem ini disimpan menggunakan Fluke 43b. ___________________________________________________________________________________- Power being absorbed by the photovoltaic (PV) panel is affected by sunlight intensity, irradiance and temperature. Therefore, a maximum power point tracking (MPPT) is introduced to the solar panels to assist in tracking the maximum power available on that particular temperature, irradiance and degree of inclination of solar panel. This project comprises two parts which is the sensor part and the dc-dc converter. The sensors part consists of voltage sensor, current sensor, temperature sensor, microcontroller and a liquid crystal display (LCD). Voltage sensor which make up by two resistors and ACS 712, current sensor are needed to keep track of the power harvested from the solar panel. Arduino is used to program the microcontroller which is Atmega 328 PU. The microcontroller acts as the “brain” of the whole circuit which read the values of the sensors and display them on the LCD. In this project, perturb and observe (P&O) method is chosen as it is the simplest method compared to the others. A Boost converter is built for the second part. Pulse Width Modulation (PWM) is regulated according to the duty cycle using the microcontroller to track the maximum power. Two PV systems, one with MPPT and the other without it are set up to compare their respective efficiency. The data of these two systems are logged using Fluke 43b.
