The simulation of the control and signal system for substation based on components

Abstract

Electrical devices in the control and signal system for substation are expressed as component model with input-control-output, and the system simulation model with certain visibility, commonality and expansibility is established. With a view to the fact that there are lots of on-off electrical components and self-governed parts in the simulation model, such methods as equivalent-node, separate-module, treetop-elimination and partial-modification are proposed to speed up the simulation.
