Contents

Description

  • Needles dispatcher for PELTON machines.
  • Switching ramp applied to the position setpoint of an injector for a PELTON machine.
  • Parameters

    Alternative forms

    Interfacing function

  • SegPal\macros\GainVar.sci
  • Computational function

  • SegPal\src\c\GainVar.c
  • Programmes de test

  • SegPal\demos\GainVar.zcos - Mono-variable case
  • SegPal\demos\GainVar_V.zcos - Multi-variables case
  • Uses of test programs. - The mono/multi variable choice is made by the sizing of the GVini vector

  • Mono-variable case (GVi 1 row 1 column)
  • Multi-variable case (GVi n rows 1 column)
  • Notes

    When switching jets, the objective of the GainVar component is to adapt and guarantee the time constants of the injector operating laws, so that they open, or close, in the same time, at a constant flow (or power) constraint.

    In the HYDROTUR diagrams of PELTON turbines, the variable gain modulates the injector setpoint in the SYSCOP copying systems of the positioners.
