不需要假設 這些資訊在台電網站就有了
105年全火力機組的熱效率為43.7%

值得注意的是 復循環機組可以達到50%左右的熱效率 可惜的是發電成本比較高
線路損失率為3.85%

另外汽油引擎熱效率圖大概長這樣

在特定轉速域才能發揮最效率
※ 引述《Heavenle (Heavenly)》之銘言:
: ※ 引述《krizzard (廢怯宅魯)》之銘言:
: : 以台灣來說 80趴火力發電
: : 假設火力發電效率50趴
: 效率應該還有提升的空間,火力發電至少空污可以有效管理
: : 透過電網傳輸會有能源消耗
: : 傳到你家充進電池轉成化學能也有消耗
: : 電池化學能透過馬達轉成動能又有消耗
: : 這樣算下來火力發電50趴打折下去
: : 會不會比現行的汽油引擎約35趴的效率還低啊
: 引擎運轉的效率牽扯太多東西了,所以35%是最佳化的狀態,車子年份增加效率也會跟著
: 下降!
: : 有大大熟這塊領域可以分享一下嗎 謝謝
