Voith Hydro has signed a contract with Axia Energia to modernise the synchronous condensers at the Recife II Substation in Jaboatão dos Guararapes, Brazil. The project includes a digital and technological upgrade of electrical, mechanical and instrumentation systems originally installed in the 1980s.
This is Voith’s third delivery for the company involving digitalisation through HyCon systems, Voith’s proprietary solutions designed to increase the reliability, availability and operational efficiency of energy generation and transmission assets.
“The delivery for Recife II reinforces our commitment to acting as Axia Energia’s partner in standardised and predictive modernisation projects, always focused on ensuring maximum asset availability,” said Leandro Lucas, Sales Director for Services at Voith Hydro in South America.
Considered the main substation in the region, Recife II is responsible for supplying electrical power and reactive power to the entire metropolitan area of Recife, serving approximately 3.7 million people. The contract includes the modernisation of the systems of two 150 MVAr synchronous condensers, the components of which have become obsolete due to the unavailability of spare parts for equipment that has been in operation for more than four decades.
Among the main systems and equipment to be modernised by Voith are control, protection, excitation, vibration monitoring and instrumentation systems. The scope also includes high-, medium- and low-voltage auxiliary electrical systems such as circuit breakers, disconnect switches, start‑up and auxiliary transformers, reactors, distribution panels, lighting systems and power outlets.
Voith will also perform upgrades to mechanical auxiliary systems, such as hydrogen purge systems, water circulation systems and oil circulation systems.
