Abstract

Kondisi pembebanan pada dunia industri saat ini terdiri dari berbagai macam peralatan. Dimana sebagian besar beban industri tersebut seperti trafo, conveyor, motor listrik, crane dan mesin solder merupakan peralatan listrik yang dalam operasinya menyerap daya aktif dan reaktif. Daya reaktif yang diserap oleh beban industri sangat cepat perubahanya dan berdampak pada turunya nilai power factor pada sebuah sistem. Selain itu, beban industri seperti motor listrik dalam pengoperasianya membutuhkan peralatan tidak linier berbasis elektronika daya seperti variable speed drive. Penggunaan peralatan tidak linier tersebut menimbulkan arus harmonisa yang juga akan mempengaruhi kualitas daya berupa power factor pada sebuah sistem tenaga listrik. oleh sebab itu diperlukan adanya metode kompensasi daya reaktif yang cepat untuk memperbaiki power factor akibat perubahan beban linier yang dinamis. Penggunaan P-Q theory dapat digunakan sebagai metode perhitungan berapa besar kompensasi daya reaktif yang diperlukan agar sesuai dengan nilai yang diizinkan. Pada simulasi, kontrol PFC mampu memperbaiki power factor sistem pada nilai power factor refrensi 0.9 pada kondisi beban yang berubah ubah. Pada implementasi, kontrol PFC mampu membaca nilai power factor sistem dan mengontrol sinyal switching capacitor bank sesuai kebutuhan daya reaktif kompensasi. ================= Nowdays, Industrial system consist of many equipment that exert active and reactive power such as transformer, conveyoyr, electric motor, crane and wielding machine. Reacrive power exert by this equipment effecting power factor on the system. In addition, electical machine on the industry system need power elektronic device (non linear load) to achieve maximum efficiency. non linear equipment generates harmonic current that affects the power quality on the power system. therefore a rapid reactive power compensation method is needed to improve the power factor due to dynamic linear load changes. P-Q theory can be used as a method of calculating how much reactive power compensation is required to match the permitted values. In this final project will be designed and implemented a power factor correction control system using P-Q theory. P-Q theory method can calculate real time power factor value in a system by considering harmonic current caused by non linear load. Power Factor Correction control simulation capable to fix power factor on the system until sama as reference value (0.9) at fluctuate load condition. And Power Factor Correction control implementation capable to read power factor value than control switching capacitor bank signal fit as reactive power compensation demand.
