Load Compensation magnetic fields. Doing so causes the effective power reactive power. Electrostatic devices, on the other factor of the combination to become unity. The hand, store electric energy in fields. Actually, by charging power. The convention for assigning signs to reactive extra for supplying the reactive power, a power utility power is different for sources and loads, for which company makes it advantageous for customers to use reason readers are urged to use a consistent notation load compensation on their premises.

Fundamentals and Current Issues

For simplicity, the line is represented only by its inductive reactance Xl. From Fig.


System Compensation component of the load current, Ix. To keep the To regulate the receiving-end voltage at the rated voltages in the network at nearly the rated value, two value, a power utility may install a reactive-power control actions seem possible: compensator as shown in Fig. This compensator 1. Such compensators are employed by power utilities to ensure the quality of supply to their customers [1].

In addition, these parameters depend on the bundling arrangement of the line conductors and the nearness to other parallel lines. The characteristic behavior of a transmission line is dominated by its l and c parameters.

Parameters r and g account for the transmission losses. The fundamental equations governing the propagation of Figure. From Eqs. In Eqs. When the power-transfer velocity of electromagnetic effects on the requirement for a given length of a line increases, transmission line.

It is less than the velocity of light.

A symmetrical 1. The SIL is defined parameters l and c remain reasonably independent of as the transmission voltage.

From the foregoing 7. Midpoint Conditions of a Symmetrical Line Parameters The magnitude of the midpoint voltage depends on the power transfer.

This voltage influences the line insulation and therefore needs to be well understood. For a symmetrical line where the end voltages are held at nominal values, the midpoint voltage shows the highest magnitude variation.

Let us assume that connected at the have receiving end is a load of fixed power factor 0. To avoid over insulating the line so that it might withstand over voltages under no-load or light conditions, a common practice is to permanently connect shunt reactors at Figure.

Unfortunately, this natural Fig.

For this line, it hold the terminal bus voltages at the desired level. Furthermore, distributed line is shown in Fig. These expected over voltages in the range 0.

Therefore, special techniques must be used to control these over voltages. Using Eq. Therefore, the var requirement from the midpoint var The results of Fig. The nominal rating for this line could be Bestselling Series.

In universities the book should form an ideal basis for a postgraduate or even an undergraduate course in power systems, and several sections of it have already been used for this purpose at the University of Wisconsin and in the General Electric Power Systems Engineering Course.
