  1. RETEAUA ENERGETICA

  2. SISTEMUL ENERGETIC NATIONAL- reprezinta complexul tuturor instalatiilor in care se produce, se transforma si se consuma energia, sub diferitele ei forme

  3. Centralele electrice pot fi : • Conventionale – termocentrale si hidrocentrale • Neconventionale – eoliene si solare

  4. În termocentrale se transformă energia termică rezultată prin arderea combustibililor ( carbune, petrol, gaze naturale )

  5. Termocentralele – folosesc caldura obtinuta prin arderea combustibilului ( carbuni, petrol, gaze naturale ) • Aceasta caldura incalzeste apa care se transforma in abur • Aburul pune in miscare paletele unei turbine • Energia produsa de turbina se transforma in energie electrica cu ajutorul unui generator

  6. Hidrocentralele – au turbine a caror palete sunt puse in miscare prin caderea apei stransa in lacuri de acumulare

  7. Centralele eoliene – transforma energia vantului in energie electrica

  8. Centralele solare – folosesc lumina solara pentru producerea energiei electrice ( cu ajutorul unor panouri solare )

  9. De la centralele electrice energia electrica este adusa pana in localitate cu ajutorul unor conductori electrici subterani sau amplasati pe stalpi la mare inaltime

  10. Legatura dintre o cladire si reteaua electrica se realizeaza printr-un bransament
