PT Thredio Engineering has proudly marked a significant milestone with the successful completion of a comprehensive control and excitation system retrofit for the PLTGU Tambak Lorok Semarang, Units 1.1 and 1.2. This ambitious project involved a full-scale technological upgrade, transitioning the turbine's core control systems from the legacy GE Mark V to the state-of-the-art GE Mark VIe, while simultaneously modernizing the excitation system from the GE 9001E (Potential Source Exc. System) to the advanced GE Ex2100e. This successful execution underscores our commitment to enhancing the operational capabilities of Indonesia's critical power infrastructure.
The shift from the older Mark V to the modern Mark VIe system represents a monumental leap in control technology for the power plant. The new Mark VIe platform offers unparalleled processing speed, enhanced diagnostic capabilities, and a unified, user-friendly interface that simplifies operations and maintenance. This upgrade not only future-proofs the control system but also significantly improves unit reliability, availability, and operational flexibility, allowing for more precise and efficient power generation to support the Semarang grid.
Complementing the turbine control upgrade, the replacement of the legacy GE 9001E (Potential Source) excitation system with the sophisticated GE Ex2100e excitation system brings a new level of stability and performance to the generator. The Ex2100e provides superior voltage regulation, improved power system damping, and enhanced protection features. This critical enhancement ensures more robust and responsive control of the generator's output, contributing to overall grid stability and extending the operational life of the generating assets.
The flawless execution of this complex retrofit at PLTGU Tambak Lorok Semarang stands as a testament to PT Thredio Engineering's deep technical expertise, meticulous project management, and unwavering dedication to client success. By delivering a seamless integration of cutting-edge technology, we have empowered this vital power plant with improved efficiency, reduced maintenance costs, and the reliability required to meet future energy demands. This project solidifies our position as a trusted partner for major power generation modernization initiatives across Indonesia.
