RVX POWER

Turbine Governor

Our digital hydro governor RVX POWER Controls all types of turbines, and provides an easy-to-install product with an exceptional cost-benefit ratio.

Digital Hydro Speed Governor RVX Power

REIVAX is a global governor manufacturer for the hydro industry. Our innovated governor control solutions can be realized in the identical hardware used for our RTX POWER Excitation System or alternatively in standard PLC hardware. REIVAX is a full-service governor supplier that also provides all hydraulic components.

Ease of Maintenance

A powerful HMI interface that provides system feedback. With our easy-to-use tools you will no longer be reliant on OEM services and can reduce strain on your maintenance budgets.


Superior Performance

The RVX POWER hydro governor is the most responsive digital hydro governor on the market, combining fast dead time and low deadband.  Our fully programmable controller allows the user to make software changes and the ability to communicate with the unit PLC/SCADA and the HPU.


Increased Reliability and Turbine Efficiency

Increasing system availability through reliable equipment is imperative to our customer’s operational revenue as is ensuring each turbine/generator is operating at its highest efficiency.


PRODUCT COMMONALITY

The RVX POWER hardware, software and interface tools are identical for any type (Francis, Kaplan/Bulb or Pelton) and size turbine. In addition, the controller hardware and software tools are identical to what is used for REIVAX RTX POWER excitation system product, simplifying maintenance and testing for plant personnel.


REDUCED HYDRAULIC MAINTENANCE

REIVAX extensive hydraulic knowledge and expertise in advanced control algorithms ensures a high performance control loop while at the same time reducing actuator wear. Duplex oil filters are used, which allows for safe filter replacement while the unit is running.


DATALOGGER / SOE AND SCADA INTERFACE

Coordination with other plant events is easily done by time synchronizing the digital hydro governor RVX POWER system with an IRIG-B signal and by utilizing the high frequency (1ms) sampling capabilities of the REIVAX even recorder. An expanded Datalogger functionality with eight (8) triggers and pre/post recording allows customers to view the system behavior when any of the user configurable triggers are activated. Communication with unit SCADA/PLC is easily made with Ethernet , (Modbus TCP/IP or DNP3.0 etc.) or with RS232/485 serial connection.

PERFORMANCE

NERC testing is significantly facilitated with the RVX POWER intuitive HMI interface featuring a graphical representation of the transfer function, built-in step response feature, chart recorder and ability to change tuning parameters for the closed loop control and limiters all from one tool. At 0.001% frequency accuracy (6mHz), the RVX POWER Hydro Governor frequency deadband senses the smallest change in frequency. Total deadtime including typical hydraulic delay is well within the NERC requirement and distinguish itself among other Digital Hydro Governors on the market.


DETECTION OF ISOLATED GRID MODE

Detection and tuning in isolated operation is easily performed using the built-in simulated grid isolation feature. The user can easily change the control deadband and droop for isolated mode operation as well as the detection parameters for initiating isolated mode operation as well as returning to grid-connected mode.


OPEN PROGRAMMING

The open programming allows for adding additional advanced control algorithms, such as adaptive control for head and load, Hill chart, Runner wear Optimization etc. Users have full control to make software changes or adding new analog or digital interface points.

RELIABILITY THROUGH DESIGN

The RVX POWER hydro governor offers a variety of redundancy options, such as, redundant controller, redundant I/O unit, redundant feedback sensors, redundant PT measuring etc.  Even without redundancy the controller boost an impressive MTBF of 146,000 hours (MIL-HDBK-217F).


KAPLAN AND BULB TURBINES

REIVAX Optimizer algorithm goes beyond turbine index testing.  Runner blade and wicket gate combinations are tested during normal operation at constant load for different head levels. The optimal combination curve (CAM curve) is then loaded into the Governor to guarantee that the unit delivers the highest possible efficiency.  Produce more Power or maintain the same Power output using less water!


RELIABLE PARTNERS

REIVAX only works with the most reliable sub suppliers. Hydraulic components are sourced from Bosch/Rexroth, Parker and Atos.  Positioning feedback sensors are MLDT/LVDT from Balluf.
