The 35kV substation of the PC unit in the Sino-Saudi Ghulayyir PC&BPA integrated plant project has successfully received power supply, achieving high-standard commissioning at the same time. Recently, another success was achieved in the Sino-Saudi Ghulayyir PC&BPA integrated plant project, which is under the general contracting of Sinochem Tiantian Company: the SS80100 35kV substation of the PC unit completed its power supply process successfully, also attaining high-standard commissioning. As the third key power facility in the project to achieve \"completion upon power receipt\", following the power substation for the phenol/acetone plant and the SS80200 power substation for the PC plant, its successful commissioning marks further significant progress in the construction of the project’s power system, providing a solid foundation for the subsequent commissioning and operation of all facilities. The SS80100 substation is one of the core power supply units for the PC system; it is responsible for providing a stable power supply to key process units such as CO, DPC, DMC, the flare system, natural gas compression facilities, the methanol feedstock tank area, and the intermediate tank area, as well as to various auxiliary facilities. To achieve the goal of \"completion upon power reception,\" Tianchen Company’s project team worked in close collaboration with the client, supervisors, and various construction units, making thorough plans. By strictly adhering to the integrated plan for power reception and project completion, they carried out all the preparatory tasks, from equipment installation and calibration, setting of protection parameters, and insulation testing to the final verification of safety conditions, ensuring that every aspect met high standards for delivery. During the power reception process, unified command was exercised at the site, with the operators working in close coordination to sequentially complete a series of key steps such as line impulse testing, bus power reception, and transformer commissioning. The entire process proceeded smoothly and in an orderly manner; the system was powered on successfully on the first attempt. All equipment was operating normally with stable parameters, thereby achieving the simultaneous completion of power reception and connection with CCCC.
