Intelligent system for the measurement of power factor_ Koay Wan Fang_E3_2008_NI
Projek ini mengaitkan pembangunan sistem cerdas untuk pengukuran serta pembetulan sistem faktor kuasa. Teknik yang digunakan bagi menjalankan operasi ini adalah sudut fasa berpangkalan. Teknik sudut fasa berpangkalan, yang melibatkan penggunaan semasa dan bentuk gelombang voltan, adalah satu cara mudah untuk menentukan faktor kuasa bagi satu sistem tanpa kelengkapan canggih. Dalam projek ini, faktor kuasa adalah diukur dengan menggunakan litar berfasa sensitif. Voltan, berkadar dengan arus elektrik, adalah digunakan sebagai input pintu pagar AND. Pengeluaran pintu pagar AND disambungkan ke mikropengawal (PIC16F877A). Mikropengawal, melalui pengaturcaraan yang sesuai, menunjukkan pameran nilai faktor kuasa. Kemudian, satu mikropengawal faktor kuasa berpangkalan pembetul digunakan untuk mengganti kualiti sistem kuasa bagi faktor kuasa rendah. Dengan menggunakan algoritma yang sesuai untuk menentukan kapasitor teratur yang mencukupi, faktor kuasa akan diselaraskan kepada nilai hampir satu. ___________________________________________________________________________________ This project deals with the development of intelligent system for power factor measurement as well as power factor correction system. Technique used to carry out this operation is based on phase angle measurement. Phase angle based, which involves the use of current and voltage waveforms, is a simple way to determine power factor of a given system without sophisticated equipment. In this project, power factor is measured by using phase sensitive circuit. Voltage, which is proportional to current, is applied to the input of the AND gate. Output of the AND gate is applied to a microcontroller (PIC16F877A). Microcontroller, through proper programming, displays the value of angle and hence power factor. Then, a microcontroller based power factor corrector is used to compensate the power quality of the system for poor power factor load This involves measuring the power factor value from the load using PIC, then using proper algorithm to determine the sufficient switching capacitors in order to compensate the reactive components and thus make the power factor near to unity.
