What is Load Curve?

What is Load Curve?: Load drawn by consumers is the toughest parameter to assess scientifically. The magnitude of the load, in fact, changes continuously so that the load forecasting problem is truly a statistical one. A typical daily Representation of Load Curve is shown in Fig. 1.1. The loads are generally composed of industrial and …

Salient Pole Synchronous Generator

Salient Pole Synchronous Generator: A Salient Pole Synchronous Generator, as shown in Fig. 4.29, is distinguished from a round rotor machine by constructional features of field poles which project with a large interpolar air gap. This type of construction is commonly employed in machines coupled to hydroelectric turbines which are inherently slow-speed ones so that …

Single Line Diagram of Power System and Impedance or Reactance Diagram

Single Line Diagram of Power System and Impedance or Reactance Diagram: A single line diagram of power system shows the main connections and arrangements of components. Any particular component may or may not be shown depending on the information required in a system study, e.g. circuit breakers need not be shown in a load flow …

Balanced Three Phase Circuit

Balanced Three Phase Circuit: The solution of a balanced three phase circuit is easily carried out by solving the single-phase network corresponding to the reference phase. Figure 4.1 shows a simple, balanced three phase circuit. The generator and load neutrals are therefore at the same potential, so that In = 0. Thus the neutral impedance …
