| Summary: | 碩士 === 國立臺灣大學 === 電機工程學系 === 85 === Due to availability of time synchronism in Global Positioning
System (GPS), synchronized Phasor Measurement Unit (PMU) based
on GPS can real-time measure voltage and current phasors at
every power system bus. This method is more efficient and fast
than calculation of power flow or state estimation. This thesis
not only research into the observation of GPS 1PPS (one Pulse
Per Second) but also presents an implementable structure of PMU
and realizes and verifies it. Moreover, this thesis compares
four different digital algorithms in phasor and frequency
estimation, and selects Discrete Fourier Transform method,
DFT, which is the most appropriate for theproposed PMU.
