Abstract
Description
本開示は概略的には、電気メータの使用によって住宅又は商業環境における電気負荷の負荷の特徴を監視し、負荷の具体的な種類及び負荷それぞれの作動状態を識別するための方法及びシステムに関する。より詳しくは、本開示は、電気負荷の負荷の特徴を監視して、電気負荷の検査、分析、及び電気負荷の所有者・オペレータとの直接対話を可能にするために、その負荷それぞれに関する識別情報をシステムのオペレータ又は第三者に伝達する方法及びシステムに関する。
図1は非侵入型負荷監視(NILM)システム10のブロック図である。図1に示されたNILMシステム10は、ユーティリティサービスプロバイダ14からの電力供給に接続されている電気メータ12を含む。ユーティリティサービスプロバイダ14からの電力は、メータ12を通過して、一連の負荷16a〜16nの各々に分配される。それぞれの負荷16はメータ12を介して電力を受け取り、メータ12は負荷16a〜16nの全体の合計消費電力量を監視して計測する。個別の負荷16a〜16nそれぞれは、一般的には、住居や商業的施設等の単一の施設内に含まれている。電気メータ12は、その施設によって消費されたエネルギー量を累積して、請求及び監視目的のために、合計エネルギー消費をユーティリティに報告する。
