Non-Intrusive Load Monitoring SystemPart3: Field Test in Model Household

概要 （図表や脚注は「報告書全文」に掲載しております）

実家庭を模擬した条件でモニタリングシステムの性能評価実験を行った。単相三線式給電回路にエアコン、冷蔵庫、テレビ、白熱灯、蛍光灯、インバータ蛍光灯、IHヒータを接続し、運転する機器やその動作状態の組合せを種々に変えて、消費電力推定能力を機器毎に評価した。結果は以下のとおり。①エアコン、テレビ、蛍光灯のように、相対的に高調波の発生量が多い機器の推定結果は良好で、推定誤差±10％の範囲にデータの84％以上が入った。②高調波の発生が少なく、消費電力も小さい白熱灯、インバータ蛍光灯に対する推定能力は相対的に低かった。機器の消費電力の傾向は十分に捉えているものの、推定誤差±10％の範囲に入ったデータは50％台にとどまった。これらの機器に対しては推定アルゴリズムの改良が必要である。③以上から、一部の課題は残したものの、本システムの実家庭への適用は十分に可能であると判断した。

概要 （英文）

We carried out a test to evaluate the performance of our non-intrusive load monitoring system in a model full-scale household. Two air conditioners, two television sets, five incandescent lamps, five fluorescent lamp sets, five electronic ballast fluorescent lamp sets, an inverter-driven refrigerator and a 200V induction cooking heater were connected to a single-phase 100V three-wire feeder system for the test. The individual electricity consumption of each appliance inferred by the monitoring system was compared with the measured consumption under conditions where the combinations of appliances and their operation modes were variously changed, which simulated actual operations in an actual household. The test data were about twenty-three thousand observations. The main results are as follows: 1) The inference results for the appliances such as air-conditioners, TVs and fluorescent lamps, which generated many harmonics, showed good agreement with the measured results within approximately 10% error. 2) The inferred results for the appliances such as incandescent lamps and electronic ballast fluorescent lamps, which generated little harmonics and consumed relatively low electricity, did not show good agreement with the measured results. Although the inferred results grasped the electricity consumption trend, only half of all the data were within 10% error. We need some measurements to revise the inference algorithm for these appliances.3) Although we have some subjects to be solved, we have judged that the monitoring system could be used in a practical household.
