HYBRID COMPUTER SYSTEM INCLUDING AN ANALOG CALCULATOR FOR RAPIDLY GENERATING ELECTRIC POWER SYSTEM LOADFLOW SOLUTIONS

摘要

A hybrid loadflow computer arrangement includes a modularized analog network simulator and a digital computer which acquires and processes on-line data and operator data related to the power system for which a loadflow problem is being solved. The analog simulator includes modular circuits representative of power system buses, lines, generators and loads and the interface between the digital computer and the analog network simulator is provided by analog-to-digital and digital-to-analog converters. The hybrid arrangement operates without iteration, with the analog network simulator providing a bus voltage solution for a set of network simultaneous equations and the digital computer providing generator real power and voltage magnitude set points and real and reactive load power set points. The modular bus circuits are interconnected with the modular generator, load and line circuits to simulate the power system and operate to enforce current and voltage laws to provide the bus solution.
