INFINITE BUSBAR: The infinite bus concept is a simplifying assumption that is applied to buses or nodes with an infinite upstream fault capacity (or an equivalent upstream source impedance of zero). *What this means is that the voltage at this bus or node is always constant and any downstream disturbances do not affect the voltage. *Obviously, there is no such thing as an infinite bus in practice, but it is a useful approximation to make when modelling a connection to a large utility or grid network. Conditions/Applications: It can be applied when the power grid is sufficiently large that the action of any one user or generator will not affect the operation of the power grid. In an infinite bus : 1. System frequency is constant, independent of power flow 2. System voltage is constant, independent of reactive power consumed or supplied Join Our Blog: electricaltechnology.org/ Visit our Fb page: https://facebook/ElectricaTechnology.org
