The per-unit power output of a salient-pole generator which is connected to an infinite bus, is given by the expression, P= 1.4 \sin\delta + 0.15 \sin 2 \delta P = 1.4sinδ+ 0.15sin2δ, where \delta δ is the load angle. Newton-Raphson method is used to calculate the value of \delta δ for P = 0.8 pu.
WebBUS CLASSIFICATION INTRODUCTION Load flow studies are one of the most important aspects of power system planning and operation. The load flow gives us the sinusoidal steady state of the entire system - voltages, real and reactive power generated and absorbed and line losses.
