Modernization of voltage regulators and speed governor, deploying integrated voltage regulator and speed governor RTVX

Cachoeira Dourada (CDSA) Power Plant, belonging to Endesa Brazil, was built and expanded in 4 steps, reaching a total of 10 generating units with a power of 17 MW (X3), 54mw (X3), 84 MW (X2 ) and 105 MW (X2), totaling 654MW.

These turbines Generating Units are 7 Kaplan type and 3 Francis.

On these upgrades, the RTVX system was provided with the following items:

- Integrated voltage regulator and speed governor RTVX;
- Power Converters with Thyristors bridges up to 2000A Field and Contactors DC;
- Transformer Excitation Dry.

With the integrated regulation, we could automate the process of starting and stopping the units, and other basic automation unit, providing increased efficiency of operation.
