  • Stability transfer limit calculation in a power transmission network
    Patent number: 5566085
    Abstract: A transient or voltage stability transfer limit is calculated for a power network having at least two independent AC generators supplying a common load via separate AC transmission lines having at least one bus. Steady state values for variable characteristic electrical parameters of variable elements of the network are determined based on particular values for power transferred by the transmission lines. Static values for passive characteristic electrical parameters of passive conductive elements of the network are determined. A contingency resulting in a sudden change of at least one of the variable electrical parameters and the passive electrical parameters is selected. A post contingency steady state value for a voltage at one of the buses is calculated.
