中文摘要 | 由於全球定位系統(Global Positioning System, GPS)在同步時間上的準確, 使得以GPS為基礎之同步相量量測單元(synchronized Phasor Measurement Unit, PMU)能即時來量測電力系統各匯流排的電壓電流相量,這比以前需解電子潮流 (Power Flow)或狀態估測(State Estimation)來獲得電力系統狀態來得更快更有效 率。本論文不但對GPS之同步訊號1PPS(one Pulse Per Second)進行觀測,並提 出可行性高的同步相量量測單元架構,更進一步將其實現與驗證。同時也將比較 四種不同計算相量及頻率的數位演算法,並選擇最適當的離散傅立葉法(DFT)應 用於本論文之同步相量量測單元上。 測單元上。 |
英文摘要 | 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 faster than calculation of power flow or state estimation. This paper not only investigate the observation of GPS 1PPS (one Pulse Per Second) but also presents an implementable structure of PMU and realizes and verifies it. Moreover, this paper compares four different digital algorithms in phasor and frequency estimation, and selects Discrete Fourier Transform method, DFT, which is the most appropriate for the proposed PMU. |
