Software Description - PSCAD Initializer
An Electro Magnetic Transient (EMT) program such as PSCAD simulates the behaviour of a power system network after a disturbance, such as a fault or a circuit breaker operation. During this short period, the system gradually changes from one steady-state behaviour to another.
The purpose of the PSCAD Initializer is to set up the proper power flow conditions (e.g. correct voltage and angles at buses, active, reactive power flows between buses, etc.) prior to the disturbance. This involves a solution to the power flow equations and setting up the correct parameters of generators, sources in PSCAD, etc.
