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

Per Unit System in Power System

Per Unit System in Power System: Per Unit System in power system is usual to express voltage, current, voltamperes and impedance of an electrical circuit in per unit (or percentage) of base or reference values of these quantities. The per unit value of any quantity is defined as: The Per Unit System in Power System

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
