摘要： Loadflow computer arrangements with transient stability analysis capabilities include a modularized analog network simulator which includes modular representation of power system busses, generators, loads, tie lines, and lines interconnected to simulate the power system. Generators are represented as constant terminal voltage magnitude behind transient reactance generators, while loads are represented as constant admittance loads. The modular generator circuits are constrained by generator mechanical power and terminal voltage magnitude set points. The modular load circuits include representative load admittance values variable under loadflow conditions and constant under transient conditions. Tie line circuits are constrained by external infinite bus voltage values. The modular bus circuits are interconnected with the modular generator, load, tie line and line circuits for operation to enforce current and voltage laws to provide the loadflow solution. The modular generator circuits provide generator swing angle output values for transient analysis.

摘要： A hybrid loadflow computer arrangement includes an analog network simulator and a digital computer which interchange signals through analog input and output circuitry. The analog simulator includes modular bus, generator, load, tie line and line DC circuits representative of electric power system buses, generators, loads, tie lines and lines. The analog simulator provides tie line currents and external voltages and load currents and voltages to the digital computer for the determination of tie powers and load powers as a function of corresponding currents and voltages and the determination of whether these powers are within predetermined tolerances. The digital computer and the analog simulator iteratively operate to provide new tie powers and load powers as a function of tie powers and load powers determined in the next preceding iteration so as to produce convergence to a loadflow solution.
