en.Wedoany.com Reported - The Hubei Ezhou Power Plant Phase IV (2×1000 MW) expansion project, led by Central Southern China Electric Power Design Institute Co., Ltd. as the general contractor, achieved successful first-time synchronization of its unit to the grid at 15:18 on May 15, 2026. After grid connection, core operating parameters including the steam turbine, generator, electrical systems, and thermal control protection all met standards, with equipment operating in a stable condition.
The completion of this key milestone signifies that Unit 7 has officially entered the on-load commissioning phase, laying the foundation for the subsequent 168-hour full-load trial operation and project completion handover. As the lead unit of the EPC general contracting consortium, the project department coordinated the entire process of design, procurement, construction, and commissioning, integrating safety, quality, and schedule control throughout. Faced with challenges such as complex system integration for thermal power units, stringent process standards, difficult cross-operation coordination, and high commissioning precision requirements, the project department identified key construction difficulties in advance and formulated specialized plans; strictly controlled quality during the equipment procurement phase, efficiently advancing expediting, arrival acceptance, and unpacking inspections; strengthened on-site overall coordination during construction, coordinating subcontractors for civil works, installation, and commissioning to work in tandem, advancing processes according to electric power engineering specifications, and implementing safe and civilized construction requirements.
During the critical grid connection period, all participating personnel remained on the front line, engaging in subsystem commissioning, interlock testing, and electrical testing. The technical team repeatedly verified commissioning plans, investigated system hazards, and calibrated operating parameters; on-site management personnel provided full-time supervision, coordinating resources to resolve commissioning issues, ensuring every process met standards and every indicator satisfied grid connection requirements.
Under meticulous control, the steam turbine run-up process for Unit 7 was smooth and stable, with bearing vibration indicators surpassing specification and design excellence standards. Core parameters were in an optimal state, achieving successful run-up and perfectly meeting operating condition standards. This demonstrated the lean management capability of the lead unit in the general contracting consortium and provided core support for the subsequent grid connection.
The successful first-time grid connection of Unit 7 showcased Central Southern China Electric Power's general contracting management capabilities, professional technical strength, and efficient collaborative contract fulfillment ability in large-scale thermal power projects, earning recognition from the owner, supervisor, and all participating parties.
Currently, the unit has smoothly entered the on-load commissioning phase. Moving forward, the project department will reinforce general contracting management responsibilities, strictly control commissioning quality, steadily advance subsequent commissioning and preparations for the 168-hour full-load trial operation, uphold the bottom lines of safety and quality, and aim for high-standard contract fulfillment and high-quality engineering to drive the project towards early completion and handover.
