An abc sequence balanced by 3-ph power supply with a line voltage at 400v supplies two balanced 3 phase loads that are connected in parallel. The first load is connected in Y and has an impedance of 30+j40 ohms per phase. The second loadis delta connected and has an impedance of 60-j45 ohms. The line has an impedance of 2+j4 ohms taking the phase voltage EA as reference, determine the line currents, the phase currents per load,and the total complex power supplied by the source.
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.
