Simulation of High Voltage Transmission Lines: The electric power system has three main divisions: the power plants, the transmission system and the distribution system. The transmission lines link the generating station to the distribution system leading to other interconnections of the electrical system. Today, we are using high voltage transmission lines (EHV) for the transmission of energy between the generating station and the distribution system in India.
The main reasons are the construction of very large super-power plants that need the transmission to high voltage to use the EHV lines and high voltages the power loss is also reduced since the losses are directly proportional to the square of current.
With MATLAB, the transmission line simulation analyzes the behaviors and parameters of the transmission line under the actual conditions to simulate a long transmission line and analyze the waveforms at the sending and receiving end. The results after the simulation help to design the High Extra High Voltage Transmission Line Model.
The network is divided into two parts transmission and distribution and transmission system is the main part. Bulk electrical power transmits from the sending end to the final receiving stations by transmission line without any consumer and divided into primary and secondary parts. Transmission voltages in India are 66kV, 110kV, 132kV, 220kV, 400kV and 765kV.
The more transmission line voltages improve system performance and efficiency, and for these high voltage and high voltage transmission lines are used to transmit electrical power from the sending end to the receiving end substations. They are series resistance, series inductance, bypass capacitance and bypass conductance.
