en.Wedoany.com Reported - On May 6, good news came again from the Phase IV 2×1000 MW ultra-supercritical double-reheat coal power project at the Huainan Luohe Power Plant, constructed by China Energy Engineering Group Construction Co., Ltd.: the DCS system of Unit 7 was successfully energized on the first attempt, and the wind shell of the No. 8 high-level water collection cooling tower was smoothly topped out. The completion of these two key milestones on the same day marks an accelerated transition of the project from the equipment installation phase to the parallel phase of system commissioning and overall advancement, laying a solid foundation for subsequent reverse power transmission, full system startup, and power generation for the grid.
As a key energy project under Anhui Province's "14th Five-Year Plan," the Luohe Power Plant Phase IV project shoulders the important mission of optimizing the regional energy structure and enhancing power supply security capabilities. During the construction process, all participating parties adhered to high-standard planning and high-quality advancement, strengthened systematic coordination around the critical path, and continuously promoted the transformation of construction organization from "single-point breakthroughs" to "systematic synergy," forming a construction landscape featuring multi-disciplinary linkage and full-process control.
The successful energization of the Unit 7 DCS system is a significant indicator of the unit's construction transitioning from the installation phase to the commissioning phase. As the control center for unit operation, the DCS system is directly related to equipment operational safety and overall unit performance. The project department adhered to the benchmarking philosophy of "no best, only better," organized special planning in advance, and established a dedicated working group with the owner, commissioning team, supervisor, and equipment manufacturer. They systematically sorted out the energization process, detailed the division of responsibilities, and built a full-process closed-loop management system. Strict quality control was implemented around key links such as cable laying, panel installation, and circuit verification. Core parameters like insulation performance and grounding resistance were tested and verified item by item to ensure all energization conditions were fully met. During the energization process, all disciplines coordinated orderly, the system operated stably, and parameter indications were accurate, successfully achieving energization on the first attempt.
On the same day, the No. 8 cooling tower wind shell completed its 144th concrete pour, and the main structure was smoothly topped out. This cooling tower adopts a reinforced concrete hyperbolic shell structure with a total height of 199.721 meters, requiring high construction precision and involving significant technical difficulty. Based on summarizing the construction experience of the first tower, the project team continuously optimized the attached tripod formwork turnover process, supplemented by a hydraulic climbing platform and construction hoist, to build a safe and efficient three-dimensional construction system. During the construction process, the team adhered to the concept of lean construction, strictly controlled key links such as surveying and setting out, formwork erection, and concrete pouring, and ensured precise control of the tower's geometric dimensions and verticality through full-process monitoring, achieving simultaneous improvement in structural formation quality and aesthetic effect.
The simultaneous realization of these "two milestones" is a concentrated reflection of the project department's capabilities in systematic coordination and collaborative advancement, and also a phased achievement resulting from the concerted efforts and joint攻坚 of all participating parties. Currently, the project construction has fully entered a critical攻坚 period. Moving forward, the project department will take this opportunity to continuously strengthen safety and quality control, optimize resource allocation, accelerate unit commissioning and system improvement work, and make every effort to build a green, efficient, and technologically leading benchmark coal power project, providing solid support for the high-quality development of regional energy.
