What is meant by flat voltage profile?

In load flow calculations, “flat start” refers to the initial guess of bus voltages. I.e. All voltages 1.0 per unit at zero degrees angle. After the initial guess, the program iterates to an actual solution.

What is flat transmission line?

Flat or Infinite Transmission Line A flat transmission line is defined as a line terminated with characteristic impedance. Such line is also called Infinite Transmission Line. Since line is terminated with characteristics impedance, hence Vr = ZcIr.

What is voltage profile of transmission line?

Voltage profile of the system changes on variation of the values of loads connected to power transmission line and using these voltage values on bus 1 and bus 2 on different values of resistive loads a Artificial Neural Network is developed after training.

What is a voltage profile?

With the drop in voltage level, the reactive power demand increases. If the reactive power demand is not met, then it leads to further decline in bus voltage resulting in the cascading effect on neighbouring regions.

What is the voltage regulation of flat voltage profile system?

For flat voltage profile system all the voltage drop in the line are neglected therefore supply voltage (Vs) is equal to the Receiving end voltage (Vr) i.e Vs = Vr. Hence the voltage regulation for flat voltage profile system is zero.

How can the voltage profile be improved in a distribution system?

By supplying the reactive power locally into the system can enhance the voltage profile in the distribution system. This can be achieved by installing the capacitor banks locally into the system. Capacitors supplying the reactive power to into the system and counteract the reactive power demand by the load.

What is the advantages of higher transmission voltage co1?

Flexible power has to be available. At higher voltage, volume of conductor is reduced. Area of conductor A ∝ 1/Vs² Where Vs = Supply voltage So that material requirement is reduced and hence cost of the material and transmission is reduced.
