                                                  RatioTapChanger

A tap changer that changes the voltage ratio impacting the voltage magnitude but not direclty the phase angle across the transformer..- The attribute ltcflag specifies whether or not a TapChanger has load tap changing capabilities. If the ltcFlag is true, the attributes “highStep”, “lowStep”, “neutralStep”, “normalStep”, “neutralU” and “stepVoltageIncrement” are required.

Method Details [hide private]

__init__(self, tculControlMode="reactive", RatioVariationCurve=None, TransformerWinding=None, *args, **kw_args)
(Constructor)

 

Initialises a new 'RatioTapChanger' instance.

Parameters:
  • tculControlMode - Specifies the regulation control mode (voltage or reactive) of the RatioTapChanger.If this is omitted it implies the control mode is OFF. If the control mode is not OFF, this is required. Values are: "reactive", "volt"
  • RatioVariationCurve - A RatioTapChanger can have an associated RatioVariationCurve to define tap ratio variations with tap step changes.
  • TransformerWinding - The transformer winding to which the ratio tap changer belongs.
Overrides: TapChanger.TapChanger.__init__
