GE upgrades controls at ENGIE’s Baymina power plant in Turkey

GE has announced the successful completion of an ALSPA steam turbine controls migration to its state-of-the-art Mark VIe controls system with rotor stress controller upgrade at ENGIE Group’s Baymina power plant in Turkey.

This first-of-its-kind Migration Pack upgrade features replacement of the controls technology while keeping the system’s core hardware infrastructure intact. This modernization is expected to increase flexibility, reliability and availability of the steam turbine and help Engie make smarter operational decisions based on controls data analytics.

“Our Baymina power plant was commissioned about 15 years ago, so it was important for us to modernize our controls system,” said Hayati Yildirim, Baymina’s engineering and maintenance manager. “With GE’s hardware and software solutions, we can now react more quickly to demand conditions while reducing maintenance costs. We were also very pleased with the training provided for the new solution and look forward to continuing our strong working relationship and winning approach with GE to improve the rest of our power plant fleet operations.”

This project is the first upgrade from ALSPA P320 V1 controlsࢀ”a technology originally developed by Alstomࢀ”to GE’s Mark VIe system.

The solution, which includes engineering, commissioning and training, retains the control system footprint, the applicative process program and the input-output modules and associated wiring work on-site, and it offers a shorter outage time and less power generation loss.

In addition, a new steam turbine stress calculator, Turbomax, was implemented to help ensure accelerated startup time while improving reliability and availability. Turbomax controls the trade-off between starting time and rotor life. It provides an increased accuracy of the stress calculation, which ensures efficient operation.

Says Olivier Jamart, GE’s Power Automation & Controls General Manager. “Developed in three years, our Migration Pack not only delivers the latest Mark VIe technology, but also helps plant operatorsࢀ”like Bayminaࢀ”benefit from cost savings, allowing for up to 30 per cent reduction in outage time when compared to a full scope replacement of the existing controls system and lower system disruption risk.

“This solution features the latest cybersecurity solutions, as well as better operator decision-making and troubleshooting based on controls data to help increase reliability and availability of the plant asset.”

Cybersecurity can be further strengthened by GE’s Baseline Security Center, an integrated set of tools, configurations and services focused on reduction of cyber risk.

Engie’s 770 MW, gas-fired Baymina plant is located in Ankara and generates electricity for the capital, which has 1.6 million households. The combined-cycle power plant began operation in December 2003 with two of GE’s 9FA.03 gas turbines (235 MW each) and an Alstom DKY224-4N4/B steam turbine (325 MW).
