私はしばらくの間、OpenModelica の ThermoPower ライブラリ内で作業しており、最初に Brayton および Rankine パワー サイクルを最初にモデル化することにより、複合パワー サイクルを構築しようとしています。

ポンプを使用しようとするたびに、次のようなエラーが常に表示されます。

[1] 10:31:00 Translation Error
[ThermoPower.Examples: 2523:70-2523:81]: Variable q_nom not found in scope ThermoPower.Examples.RankineCycle.Models.

[2] 10:31:00 Translation Error
[ThermoPower.Examples: 2531:21-2531:69]: Cyclically dependent constants or parameters found in scope : {q_nom}, {head_nom} (ignore with -d=ignoreCycles).

ポンプを選択すると、モデルに対してこれらのエラーが常に宣言されます。私はさまざまな種類のソリューションを試しましたが、すべて成功しませんでした。

  1. ベクトル形式、つまり : を使用して、ポンプのコンポーネント パラメータの値を宣言しようとしましたq_nom = {1,1,1}。シミュレートしようとすると、同じエラーがポップアップします。

  2. エラーを直接クリックして、ThermoPower.PowerPlants にリダイレクトされるようにしました。ここで私はコード行に向けられています:

    function flowCharacteristic = ThermoPower.Functions.PumpCharacteristics.quadraticFlow (q_nom= q_nom, head_nom=head_nom);

ここで、q_nom と head_nom の値を手動で入力しようとしましたが、成功しませんでした。また、関数を「再宣言」しようとして、モデルの上部にある上記のコード行をコピーしようとしましたflowCharacteristic。これは、宣言できないクラスを誤って再宣言したというエラーになるだけです。

他の解決策を試しましたが、成功しませんでした。

この問題のトラブルシューティング方法についてアドバイスがありましたら、お気軽に以下にご記入ください。

アップデート:

これは、私がしばらくの間取り組んできたモデルのコードです。
