en.Wedoany.com Reported - At 18:58 on June 2, the #1 steam turbine of Jinxing Power Plant successfully completed its first rotation, smoothly reaching and stabilizing at the rated speed of 3000 r/min, marking another key milestone before commercial operation.

Maintaining the turbine at rated speed is a core prerequisite for grid-connected power generation of thermal power units and serves as a critical test for installation and commissioning quality. To ensure a one-time success, the plant focused on risk points such as critical vibration, oil temperature and pressure fluctuations, and vacuum tightness, organizing a joint task force comprising the owner, commissioning, construction, and supervision teams. Technical personnel completed subsystem commissioning in advance, conducting comprehensive reviews of shaft alignment, pipeline sealing, and protection interlocks, and closed all potential hazards. During the rotation, specialists in operations, thermal control, and turbine systems were stationed at key positions, precisely managing steps such as warming, speed increase, and critical speed crossing, with zero errors throughout the process. After rotation, parameters including shaft vibration, bearing temperature, vacuum, and oil pressure were all excellent, with stable operation, clearing key obstacles before grid connection and laying a solid foundation for subsequent load testing.

Next, Jinxing Power Plant will continue fine-tuning equipment, addressing defects, and steadily advancing trial operations, striving to ensure the early grid connection and power generation of Unit #1, contributing to the high-quality development of Huadian Energy Company and regional energy supply security.
