Northeast China Power Grid 500 kV smart substation construction progresses smoothly

In order to improve the reliability of power supply in the northeastern power grid, improve the northeastern grid structure, and create a 500kV intelligent substation construction, the first 500kV smart substation of the State Grid—the Northeast Power Grid Company Changchun South (Jincheng) substation, since June of this year The construction began on the 30th. Up to now, the foundation construction of 500 kV and 220 kV has been completed. The completion rate of the fence foundation is 69%, the completion rate of the main grounding grid is 20%, and the roads in the station are hardened. The concrete at the bottom of the accident oil pool is under construction. completed.

Since the beginning of summer this year, continuous large-scale rainfall in the Changchun area has caused great impact on the construction progress of the Changchun South 500-kilovolt transformer substation. The construction period has lagged behind. In order to ensure the progress of the project, the Ministry of Infrastructure timely organized thematic coordination and implementation of the meeting, combined with actual statistics of the actual amount of work on the site, and carried out reversed shift schedules according to the node duration, requiring all participating units to actively take effective measures to concentrate their efforts on improving efficiency and rush time. Ensure that the established schedule goals are successfully achieved.

From September 1st, the construction unit has increased manpower, construction machinery and equipment investment, and implemented a 24-hour uninterrupted work system, which has greatly improved work efficiency. The staff of the Changchun Bureau Infrastructure Office shall be stationed at the construction site day and night to supervise the safety and quality during construction, and cooperate with the supervision unit to conduct random inspections at any time to detect the problems existing in the construction process and require the construction unit to ensure the safety and quality of the project. Under the premise of this, try to improve work efficiency and lay a solid foundation for the project to be put into operation according to the intended target next year.

Leaders of Northeast Power Grid Corporation attached great importance to project construction and conducted several on-site inspections and guidance work. Li Yifan, chairman of Northeast Power Grid Corporation, and Dong Enfu, deputy general manager of the Northeast Power Grid successively gave on-the-spot guidance on the construction of Changchun South and went to the site for inspection work. The problems encountered were investigated one by one, and responsibilities were clearly defined and implemented.

Northeast Power Grid Co., Ltd. actively coordinates the relationship between parties and resolves various issues in a timely manner. All participating units strictly implemented all construction management regulations issued by the State Grid Corporation, and built the Changchun South (Jincheng) subproject into high-quality projects to ensure that the flag-winning targets were achieved.
