Q2: Rights of way for transmission circuits are difficult to obtain in urban areas, and cxisting lines are often upgraded by reconductoring the line with larger conductors or by reinsulating the line for operation a t higher voltage. Thermal considerations and maximum power which the line can transmit are the important considerations. A 138-kY line is 50 km long and is composed of Partridge conductors with fiat horizontal spacing of 5 m between adjacent conductors. Neglect resistance and find the percent increase in power which can be transmitted for constant IVsl and IVRI while o is limited to 45° (a) If the Partridge conductor is replaced by Osprey, which has more than twice the area of aluminum in square millimeters. (b) If a second Partridge conductor is placed in a two-conductor bundle 40 cm from the original conductor and a center-to-center distance between bundles of 5 m, and (c)If the voltage of the original line is raised to 230 k V with increased conductor spacing of 8 m.
Short Transmission Line
A short transmission line is a transmission line that has a length less than 80 kilometers, an operating voltage level of less than 20 kV, and zero capacitance effect.
Power Flow Analysis
Power flow analysis is a topic in power engineering. It is the flow of electric power in a system. The power flow analysis is preliminary used for the various components of Alternating Current (AC) power, such as the voltage, current, real power, reactive power, and voltage angles under given load conditions and is often known as a load flow study or load flow analysis.
Complex Form
A power system is defined as the connection or network of the various components that convert the non-electrical energy into the electric form and supply the electric form of energy from the source to the load. The power system is an important parameter in power engineering and the electrical engineering profession. The powers in the power system are primarily categorized into two types- active power and reactive power.
