SYSTEM AND METHOD FOR MONITORING TRANSIENT STABILITY IN A HYBRID LOADFLOW COMPUTER ARRANGEMENT WITH TRANSIENT STABILITY ANALYSIS CAPABILITY

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 during transient analysis. 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 generator swing angles and generator rotational velocities to the digital computer. The computer monitors the generator swing angles and rotational velocities to determine and indicate whether they are within predetermined tolerances.
