WebFor steady-state or stable operation, the load angle δ must be less than 90 degrees. The theoretical stability limit of the stable condition occurs when δ = 90⁰. The capability curve is based upon the phasor diagram of the synchronous machine. The phasor diagram of a cylindrical rotor alternator at lagging power factor is shown below: Web22 May 2024 · The power in the load can be determined by using I2R where I = E / (Ri + R), yielding. P = ( E Ri + R)2R. Using our normalized values of 1 volt and 1 Ω, P = ( 1 1 + R)2R. After expanding we arrive at: P = R R2 + 2R + 1. We now have an equation that describes the load power in terms of the load resistance. WebThe swing curve is the plot or graph between the power angle and time. 7. What is the use of swing curve? It is usually plotted for a transient state to study the nature of variation in power angle for a sudden large disturbance. From the nature of variation in power angle the stability of a system for any disturbance can be determined. 8. khc holdings pte ltd
