Abstract
Description
本出願は、2017年10月26日出願の日本出願第2017-207464号に基づく優先権を主張し、前記日本出願に記載された全ての記載内容を援用するものである。
上記のような太陽光発電システムにおいては、例えば、多数の太陽光発電装置の1基ごとに、太陽光発電パネルの発電出力は、パワーコンディショナを介して、交流電力となり、全基に共通の変電機器に提供される。一方、太陽を追尾するための姿勢制御は、個々の太陽光発電装置ごとに行われる。但し、日射センサ等の気象センサを、個々の太陽光発電装置ごとに装備するのはコスト的に得策ではないため、太陽光発電システムが設置されている場所の一箇所に気象センサが設置されている。
かかる課題に鑑み、本開示は、システム全体の監視と追尾制御とをさらに効率的に行う太陽光発電システムを提供することを目的とする。
本開示の太陽光発電システムによれば、システム全体の監視と追尾制御とをさらに効率的に行うことができる。
本発明の実施形態の要旨としては、少なくとも以下のものが含まれる。
この場合、複数基の太陽光発電装置の全体を監視制御する監視制御部により、該当する駆動制御部に較正動作を行わせることができる。
この場合、全ての太陽光発電装置で同時に異常が発生しているとは考えにくいため、日射センサが、実際の日射より高い数値又は低い数値を検出している、と判定することができる。
この場合、監視制御部は、太陽光発電装置が設置されている場所に制約されることなく、任意の場所に置くことができる。
以下、本発明の一実施形態に係る太陽光発電システムについて、図面を参照して説明する。
図1及び図2はそれぞれ、1基分の、集光型の太陽光発電装置を、受光面側及び背面側から見た斜視図である。図1において、太陽光発電装置100は、上部側で連続し、下部側で左右に分かれた形状の太陽光発電パネル1と、その支持装置2とを備えている。太陽光発電パネル(アレイ)1は、背面側の架台11(図2)上に集光型太陽光発電モジュール1Mを並べて構成されている。図1の例では、左右のウイングを構成する(96(=12×8)×2)個と、中央の渡り部分の8個との、合計200個の集光型太陽光発電モジュール1Mの集合体として、太陽光発電パネル1が構成されている。
日没後の太陽光発電装置100は、例えば、太陽光発電パネル1の受光面を下向きにした水平な姿勢となり、翌日の日の出まで待機する。
図4は、一例として、太陽光発電装置100が、例えば縦横にそれぞれ8基ずつ並び、合計64基の太陽光発電装置群200を含む、太陽光発電システム300となっている状態を示す略図である。監視制御部6は、全ての太陽光発電装置100と通信可能に接続されており、各太陽光発電パネル1の姿勢を個別に、又は、統括的に制御することができる。
次に、監視制御部6による監視制御動作の一例について図7のフローチャートを参照して説明する。このフローチャートの処理は定期的に実行される。図において、気象センサ7の検出出力に基づいて、監視制御部6は、日射量から発電電力を予測する(ステップS1)。次に、監視制御部6は、いずれかの太陽光発電装置100の発電電力が、予測値の90%以下まで低下したか否かを判定する(ステップS2)。通常、実際の発電電力は予測値の90%より高い値となる。ここで90%より上であれば、問題は無いので、処理は終了となる。
なお、日射センサ7sの異常に関しては、日射センサ7sの感度が低下することも考えられる。その場合は、図7のステップS1における予測値が低下し、発電電力が予測値を上回ることもあり得る。そのような場合も想定すれば、ステップS2において例えば予測値の110%以上まで上昇という事象と、全装置で同様の傾向あり(ステップS4)の事象とにより、日射センサ7sの異常を検出することも可能である。
以上のように、この太陽光発電システム300では、監視制御部6が、駆動制御部3を遠隔制御可能である。また、監視制御部6は、全ての駆動制御部3、全てのパワーコンディショナ4、変電機器5、及び、気象センサ7と通信可能であり、通信によって収集した情報に基づいて、異常の発生の検出、及び、異常の種類を判定する機能を有する。
なお、今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は請求の範囲によって示され、請求の範囲と均等の意味及び範囲内での全ての変更が含まれることが意図される。
