Steady State Model of Wind Farm • As a negative load (PQ bus) - assumes a generated real power and a given power factor, with which the consumed reactive power is calculated. • As a voltage controlled (PV bus) - when the voltage at the connection point need to be controlled at normal voltage by providing reactive power support • PX bus model - the real power is known and the reactive power is calculated as a function of the magnetizing reactance of the generator • RX bus model - assumes resistance and reactance of both stator and rotor as well as the mechanical output power P m to be known variables
Steady State Model of Wind Farm, Contd. An improved PQ bus model has been proposed considering the steady state properties of the induction generator, such that the reactive power Q is calculated by Q ≈V 2 ⎛ ⎜ ⎝ X − X X X c m + c where, X c is capacitive reactance X m is magnetizing reactance X is sum of stator and rotor reactances V is terminal voltage P is real power of the generator The improved PQ bus model requires that the specified reactive power Q be updated after each iteration of the load flow m ⎞ ⎟ ⎠ X V * A.E.
