Consulting Services in South America

As part of commissioning Brazil’s largest gas power plant—incorporating numerous GE Vernova-designed systems—for operation, power company CELSE commissioned GE Vernova to conduct a pre-operational electromagnetic transient (EMT) study to assess the impact that connecting the plant to the 500kV transmission grid would have.

The study’s final issue and additional grid code compliance tests GE Vernova conducted enabled the plant to commence commercial operation, resulting in an estimated $800K (US) in daily revenue for the power company.

ENGIE commissioned an extensive assessment to evaluate the potential risk of subsynchronous torsional interactions (SSTI) between the Pampa Sul power plant and the Melo HVDC Back-to-Back (BtB) facility located in Uruguay. This assessment was indispensable for securing authorization for the commercial operation of the Pampa Sul plant.

GE Vernova conducted a thorough and comprehensive analysis, proposing viable strategies for the mitigation of the SSTI phenomenon and the protection of the turbine shaft. This study enabled ENGIE to formulate the necessary strategies to address SSTI, thereby reinforcing the credibility and collaborative efforts between GE Vernova, ONS, and ENGIE.

GE Vernova was contracted to uprate 18 fixed series capacitors (FSCs) along Brazil’s North/South Interconnection, a single 500kV compact transmission line. This line can transmit up to 1300mW of power and has operated reliably since it was first energized in 1999.  

GE Vernova believed that its transmission efficiency could be increased by implementing these new FSCs. The team at Consulting Services supported our colleagues in the GE Vernova Wind business, and delivered information technology outsourcing (ITO) support and operability test report (OTR) studies for the FSCs, which ultimately led to replace six of the eight FSC banks authorized by GE Vernova, further solidifying South American confidence.
