REIVAX TO REPLACE WOODWARD GATE SHAFT GOVERNORS
Montreal (April 5th, 2023) – REIVAX NORTH AMERICA, a leading provider of excitation systems and digital governors, was awarded a contract to retrofit three (3) Woodward gate shaft governors.
The existing systems include Woodward flyball governor controls and a mechanical linkage to a pressure relief valve (PRV) for regulating the penstock pressure during an emergency shutdown.
Under the contract, the existing Woodward flyball governor will be replaced with new REIVAX RVX Energy digital governor control panels, each with a 15″ HMI screen.
REIVAX is also providing Electro-Hydraulic-Interfaces (EHIs) on manifolds, which will be bolted in place in lieu of the fly-ball regulator assembly. The existing distribution valve for the wicket gate will remain. New position sensors will be added for the wicket gate distribution valve and servo motor.
As part of the retrofit, the mechanical linkage between the wicket gate and PRV will be removed and replaced with a digital control loop.
REIVAX is also providing Electro-Hydraulic-Interfaces (EHIs) with manifolds for the PRVs. The existing distribution valve for the PRVs will remain and new position sensors will be added for the distribution valve and servo motor.
“REIVAX RVX Energy governor panel is an excellent alternative for upgrading Woodward Gate shaft or Woodward Cabinet governors. REIVAX digital governors reduces the need for maintenance and provides an easy-to-use interface to operators and engineers” said Mike Wallin, CEO and President of REIVAX NORTH AMERICA
