Hybrid analyzer for fast load flow and transient solution of power systems

摘要

This invention relates to hybrid computer arrangement for representing an electric power system and for generating load flow solutions therefor. The employment of modular circuits for simulating actual system buses and transmission lines as utilized and circuit stability is ensured by the application of Nyquist stability criteria. Bus modules include the added feature of proportional plus integral control to allow for low proportional gain and high damped response.
