Reduce your commissioning time and achieve earlier commercial operation. Whether you perform the commissioning yourself or if done by a Reivax service engineer, our system offers various tools to make pre-commissioning and spinning tests easier. From built-in analog and digital I/O testing to auto-tuning of the control loop.

NERC testing is significantly facilitated with the intuitive RTX Power excitation system software interface featuring a graphical representation of the IEEE 421.5 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. Power System Stabilizer (PSS) testing is easily performed using the built-in frequency response tool without the need of additional external instrumentation.

Keep your excitation system in top shape with Reivax periodic testing tools. Thyristor bridge testing is made possible without operating the generator or motor by using the open loop control feature where customers are able to directly change the firing angle in order to verify the correct operation of all SCRs and monitoring circuits. The correct operation of current sharing between bridges, SCR temperatures, fuse and cooling fan monitoring can also be validated using our HMI interface.

The Reivax design features a segregation of the RTX Power excitation system controller from the heat emitting power section, so that electronics are not exposed to unnecessary heat. The electronic circuitry is shielded from the heat in a dedicated enclosure or section in the cubicle. Reivax design philosophy is to overdesign each system by 20-30% compared to the nominal operating requirements in order to increase the life expectancy of the excitation system.

Depending on budget constraints as well as physical space limitations, Reivax provides customers with the solution that offers the best value. A selection of redundancy is offered for power supplies, cooling fans, control channels, I/O interface and thyristor bridges.

Customers can select which configuration that match their needs. Sharing of current between two (2) or more thyristor bridges or a hot stand-by configuration with two (2) thyristor bridges.
