Question
Download Solution PDFएक 40 MVA, 11 KV, 3-चरण, 50 Hz, 4 - ध्रुव वाले टर्बो आवर्तित्र में 15 सेकेंड का एक जड़त्व स्थिरांक है। 20 MW का एक इनपुट 15 MW की आउटपुट शक्ति विकसित करता है। तो त्वरण क्या है?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFVA रेटिंग (S) = 40 MVA
वोल्टेज (V) = 11 kV
आवृत्ति (f) = 50 Hz
ध्रुवों की संख्या (P) = 4
जड़त्व स्थिरांक (H) = 15 सेकेंड
इनपुट शक्ति (Pin) = 20 MW
आउटपुट शक्ति (Pout) = 15 MW
त्वरण शक्ति Pa = Pin - Pout = 5 MW
\({P_a} = M\frac{{{d^2}\delta }}{{d{t^2}}} = M\alpha\)
\(\Rightarrow {P_a} = \left( {\frac{{SH}}{{180f}}} \right)\alpha\)
\(\Rightarrow \alpha = \frac{{5 \times {{10}^6} \times 180 \times 50}}{{40 \times {{10}^6} \times 15}}\)
