The structures having long distance transmission tend to produce heavy power flow with increasing electric power demand. In addition, some independent power producers (IPP) and power producer and suppliers (PPS) are participating in the power generation business, which makes power system dynamics more complex. However, there was little observation as a whole power system. In this paper the authors present a global monitoring system of power system dynamics by using the synchronized phasor measurement of demand side outlets. Phasor Measurement Units (PMU) are synchronized based on the global positioning system (GPS). The purpose of this paper is to show oscillation characteristics and methods for processing original data obtained from PMU after certain power system disturbances triggered by some accidents. This analysis resulted in the observation of the lowest and the second lowest frequency mode. The derivation of eigenvalue with two degree of freedom model brings a monitoring of two oscillation modes. Signal processing based on Wavelet analysis and simulation studies to illustrate the obtained phenomena are demonstrated in detail.","ja":"筆者らは，家庭用コンセント電圧の多地点同期位相計測に基づく独自の広域電力系統観測システムとその応用に関する研究を行っている．本論文では，特に計測データから大規模系統の主要な電力動揺モードを抽出して2自由度系振動モデルで再現するとともに，電力系統の標準モデルを用いた解析結果と比較し，その手法の有用性を確かめている．"},"publication_date":"2005-04-01","publication_name":{"en":"IEEJ Transactions on Power and Energy","ja":"電気学会論文誌B (電力・エネルギー部門誌)"},"volume":"125","number":"4","starting_page":"417","ending_page":"424","languages":["jpn"],"referee":true,"identifiers":{"doi":["10.1541/ieejpes.125.417"],"issn":["0385-4213"]},"published_paper_type":"scientific_journal"},"priority":"input_data"}
