Methods of Voltage Control

Methods of Voltage Control: Methods of Voltage Control – Practically each equipment used in power system are rated for a certain voltage with a permissible band of voltage variations. Voltage at various buses must, therefore, be controlled within a specified regulation figure. This article will discuss the two methods by means of which voltage at […]

Power Flow through a Transmission Line

Power Flow through a Transmission Line: Power Flow through a Transmission Line – So far the transmission line performance equation was presented in the form of voltage and current relationships between sending-and receiving-ends. Since loads are more often expressed in terms of real (watts/kW) and reactive (VARs/ kVAR) power, it is convenient to deal with […]

Equivalent Circuit of a Long Line

Equivalent Circuit of a Long Line: So far as the end conditions are concerned, the Equivalent Circuit of a Long Line can be established in the form of a T- or π-network. The parameters of the equivalent network are easily obtained by comparing the performance equations of a π-network and a transmission line in terms […]
