18EPC405 TRANSMISSION AND DISTRIBUTION

Objectives To study the structure of electric power system and to develop expressions for the computation of transmission line parameters. To obtain the equivalent circuits for the transmission lines based on distance and to determine voltage regulation and efficiency. To understand the mechanical design of transmission lines and to analyze the voltage distribution in insulator strings to improve the efficiency. To study the types, construction of cables and methods to improve the efficiency. To study about distribution systems, types of substations, methods of grounding, EHVAC, HVDC and FACTS. I. TRANSMISSION LINE PARAMETERS Structure of Power System – Parameters of single and three phase transmission lines with single and double circuits – Resistance, inductance and capacitance of solid, stranded and bundled conductors – Symmetrical and unsymmetrical spacing and transposition – Application of self and mutual GMD – Skin and proximity effects – Typical configurations – Con
