Fault Module¶
Fault calculation module exposes classes capable of running ERACS Fault studies.
-
class
TEracsFault¶ Low-level implementation of the Fault interface. All methods in this class provide low-level functionality involving direct interactions with the DLL. Contains minimal logic and safety checks.
-
GetFileNames(AOutParameterProperties)¶ - Parameters
AOutParameterProperties (list) – This argument acts as an out parameter. An empty list should be passed in, and the various file names will be appended to the list [lstResults, cdResults, cdData].
-
ChangeImpedance(ASeqNum, AStatorR, AReactance)¶ Change the impedance for a given synchronous machine.
- Parameters
ASeqNum (int) – Sequence number of machine to change impedance of.
AStatorR (float) – The stator resistance of the machine.
AReactance (float) – The transient reactance of the machine.
- Raises
TEracsArgumentError – If the arguments are of the incorrect type.
-
-
