To provide a technique which can accurately measure a separation between an overhead transmission line and a ground surface shape while reflecting deviation generated on the ground surface shape and reduce time, cost or the like needed for measurement in this case.SOLUTION: A power line monitoring system comprises: an initial value data acquisition part 12 which acquires three-dimensional data measured about a ground surface shape 5 of an arrangement region of an overhead transmission line 2 using a flight vehicle as initial value data; a displacement magnitude data acquisition part 12 which acquires and analyzes observation data periodically transmitted from a satellite 31 about the ground surface shape 5 and extracts temporal displacement magnitude of the ground surface shape 5 to make it displacement magnitude data; an installation information holding part 13 which holds installation information of the overhead transmission line 2; and a separation detection processing part 15 which calculates a separation between the overhead transmission line 2 and the ground surface shape 5 using the initial value data, the displacement magnitude data and the installation information.SELECTED DRAWING: Figure 1

    【課題】架空送電線と地表面形状との離隔を、当該地表面形状に生じる変位を反映させつつ、精度よく計測することができ、しかもその場合であっても計測のために要する時間やコスト等の低減が図れる技術を提供する。【解決手段】架空送電線2の配置領域の地表面形状5について飛行体を利用して実測した三次元データを初期値データとして取得する初期値データ取得部12と、前記地表面形状5について衛星31から定期的に送られる観測データを取得して解析し、前記地表面形状5の経時的な変位量を抽出して変位量データとする変位量データ取得部12と、前記架空送電線2の設置情報を保持する設置情報保持部13と、前記初期値データ、前記変位量データおよび前記設置情報を用いて、前記架空送電線2と前記地表面形状5との離隔を算出する離隔検出処理部15と、を備えた送電線監視システムを構成する。【選択図】図1
