最初に、本実施形態の概要について説明する。本実施形態の監視装置は、予め用意しておいた複数の電気機器各々の特徴量(参照特徴量)を組み合わせた特徴量と、例えば分電盤で測定した所定の単位(例:各家庭、ある家庭内の特定の部屋、各オフィス等)内の総消費電流、総消費電力、電圧等である測定データから抽出した特徴量(測定特徴量)とを比較することで、電気機器の稼動状態を推定する。なお、本実施形態では、所定の単位(例:各家庭、ある家庭内の特定の部屋、各オフィス等)に設置された電気機器と同種の電気機器を他の場所(例:研究室、実験室等)に置いて測定した測定データ(例:消費電流、消費電力、電圧等)を利用して、各電気機器の参照特徴量を生成する。
第1の実施形態では、機器特徴量を抽出するための参照データを測定した際の測定条件と、測定特徴量を抽出するための所定単位測定データを測定した際の測定条件(所定の単位の単位特徴情報で特定される条件)との違いに起因して、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、「測定特徴量」を補正した。これに対し、本実施形態では、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、「機器特徴量」を補正する。
第1及び第2の実施形態では、機器特徴量を抽出するための参照データを測定した際の測定条件と、測定特徴量を抽出するための所定単位測定データを測定した際の測定条件(所定の単位の単位特徴情報で特定される条件)との違いに起因して、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、「測定特徴量」又は「機器特徴量」を補正した。これに対し、本実施形態では、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、測定特徴量を抽出する前の「所定単位測定データ」を補正する。
第1乃至第3の実施形態では、機器特徴量を抽出するための参照データを測定した際の測定条件と、測定特徴量を抽出するための所定単位測定データを測定した際の測定条件(所定の単位の単位特徴情報で特定される条件)との違いに起因して、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、「測定特徴量」、「機器特徴量」又は「所定単位測定データ」を補正した。これに対し、本実施形態では、測定特徴量と機器特徴量との間に現れる差を打ち消す方向に、機器特徴量を抽出する前の「参照データ」を補正する。
第1乃至第4の実施形態では、測定環境の単位特徴情報や、参照データを測定した際の測定条件などを考慮して測定特徴量を補正するための補正情報(例:伝達関数)を生成し、当該補正情報を用いて補正後の特徴量やデータを得ていた。これに対して、本実施形態では、所定の単位で測定された所定単位測定データと、参照データとに基づいて、「測定特徴量」、「機器特徴量(参照特徴量)」、「所定単位測定データ」及び「参照データ」の少なくとも1つを補正するための補正情報(例:伝達関数)を生成し、当該補正情報を用いて補正後の特徴量やデータを得る。このような本実施形態によれば、第1乃至第4の実施形態で利用していた単位特徴情報が不要となる。
図16に、本実施形態の機能ブロック図の一例を示す。本実施形態の監視装置10は、測定データ取得部12と、参照データ記憶部47と、補正情報作成部70と、補正部55とを有する。測定データ取得部12及び参照データ記憶部47の構成は、第1乃至第4の実施形態と同様であるので、ここでの説明は省略する。補正部55は、補正情報作成部70が作成した補正情報(例:伝達関数)を用いて、補正後の特徴量やデータを得る点を除き、第1乃至第4の実施形態と同様であるので、ここでの説明は省略する。
次に第5の実施形態について、具体的な実施例を用いて説明する。まず、あるユーザ環境において、電源幹線における電圧波形と電流波形データを測定する。電圧波形は、例えばユーザ環境におけるコンセントから抵抗分割などを用いて測定する。電流波形は、分電盤の基幹部分にクランプ式のCT(Current Transformer)などを設置して測定する。測定した電圧電流は、電圧が負から正になるゼロクロス点で位相合わせを行い、電圧電流波形が各測定で同じ位相のデータになるように位相調整を行う。
第5の実施形態では、電流波形や特徴量の各値を個別に補正するのではなく、強度と位相の2値のずれを用いて全ての値を補正できるので、電流波形だけでなく、高調波の強度や位相などの特徴量ベクトル等も補正することができる。
