Teoremy Thevenin i Norton 's
Teoria Thevenin 's texte that any linear electrical network wigh voltage and current sources and resistances can be a single voltage source in serie a resistor. Norton' s theorem, on thee texter hund, replaces the network with a current source in parallel with a resistor.
Step 1: Identify the Portion of the Circuit
Wybranie tego obszaru, gdzie mają być obwody, kiedy chcą, żeby te analizy były niepotrzebne, te które są section of interest. Removie te load if present, te focus on thee source and it s internal elements.
Step 2: Obliczanie Thevenin Equivalent
To jest to, co jest równoważne, to jest to:
- Turn off all independent sources by replaceing voltage sources with short objects andd current sources with open objects.
- Oblicz, że równoważny opór widzi w tym momencie terminale.
- Określ te open-obwody voltage across thee terminals with all sources active.
Thevenin voltage is thee open- obirvit voltage, and thene Thevenin resistance is they equivalent resistance calculated in thee previous step.
Krok 3: Kalkulator Norton Equivalent
Te Norton equivent can be derived frem thee Thevenin equivent:
- To Norton territs is thee short- obwody territs at thee terminals.
- To Norton resistance is thee same as theven resistance.
Use the relation: behin1; FLT: 0 behind 3; FLT: 0 behind 3; FLT: 1 behind 3; FLT: 1 behind 3; N behin1; FLT: 2 behind 3; FLT: behind 1; FLT: 3 behind 3; TH behind 1; FLT: 4 behind 3; FL3; / R behind 1; FLT: 5 behind 3; FLT: 3; TH behin1; FLT: 6 behind 3; FLT: 3; FLT: 7 behind; 3d; FLT: 7 behind; 3d;
Step 4: Acquery Equivalents to Power System Design
Replace complex parts of thee obrintet with their ir Thevenin or Norton equivalents to simplify analysis. Thi approach helps in designing load connections, fault analysis, and system optimization.
Dodatek Tips
Ensure all sources are correctly turned of f when calculating resistances. Verify they equivalence by re-assemblg the oburits andd comparing voltages andd currents.
