Transformer
[Distribution flow solver (network)]

---

Detailed Description

The transformer is one of the more complex objects in the powerflow network.

Implemented as a link, the transformer configuration exports a type property that allows the transformer to operate as and single phase transformer, a wye-wye connected transformer, a delta-grounded wye tranformer, a delta-delta transformer, and as a center-tapped transformer.

The transformer exports a phase property that is a set of phases and may be set using the bitwise or operator (A|B|C for a 3 phase line).

Function Documentation

EXPORT int create_transformer	(	OBJECT **	obj,
		OBJECT *	parent
	)

REQUIRED: allocate and initialize an object.

Parameters:

	obj	a pointer to a pointer of the last object in the list
	parent	a pointer to the parent of this object

Returns:

1 for a successfully created object, 0 for error

Definition at line 295 of file transformer.cpp.

EXPORT int init_transformer

(

OBJECT *

obj

)

Object initialization is called once after all object have been created.

Parameters:

parent

a pointer to this object's parent

Returns:

1 on success, 0 on error

Definition at line 322 of file transformer.cpp.

References powerflow_object::get_id(), powerflow_object::get_name(), GL_THROW, transformer::init(), and OBJECTDATA.

EXPORT TIMESTAMP sync_transformer	(	OBJECT *	obj,
		TIMESTAMP	t0,
		PASSCONFIG	pass
	)

Sync is called when the clock needs to advance on the bottom-up pass (PC_BOTTOMUP).

Parameters:

	t0	this objects current timestamp
	t1	the timestamp which the object should move forward to

Returns:

t2, where t2>t1 on success, t2=t1 for retry, t2<t1 on failure

Definition at line 342 of file transformer.cpp.
