What is a Control and Automation Combined System?
It is a solution that combines the Excitation with the Digital Governor and with the gererating unit Automation system.
It has the responsibility of control the frequency, the active power, the voltage, the reactive power, plus to operate and monitore the generating unit subsystems. It’s a lot of responsibility, isn’t it?
This innovation emerged in 1999 in the Research and Development area of REIVAX, and revolutionized the power systems forever!
Applied for medium and small-sized hydroelectric power plants, it has an exceptional cost-benefit relationship!
RTVAX POWER
The REIVAX hardware and software platform, fully programmable and expandable, based on two already consolidated and powerful equipments Excitation System (RTX POWER) and Digital Governor (RVX POWER), was the foundation for more innovation.
Combining the functionalities and tools available in RTX and RVX, increasing the automation logics for the generating unit subsystems, results in the RTVAX POWER.
Such flexibility makes it possible to incorporate protection relays into the same cubicle, optimizing the physical space and the client’s investment. It also allows controlling the excitation and starting process of synchronous condensers, or the automation logics and frequency/power control of the unit. Flexibility and resources optimization!
