Transient Stability Module

Main Features

Comprehensive modelling of power system

	Infinate bus capability
	Modeling of synchronous machines
	Voltage behind transient reactance Parks' equations with AVR and governor modelling
	Dynamic modelling of induction machines

Assessment of dynamic behaviour of system when subjected to:

	Small disturbances (steady state stability)
	Loss or application of loads
	Loss of generation
	Switching in or out of system shunt or branch elements
	Coarse sychronising of generators or disconnected networks
	System faults, three phase and unbalanced
	Starting of large motors, synchronous or induction
	Failure of control devices, AVRs or Speed Governors

Other Features
