The first million kilowatts unit of Anhui power grid was successfully connected to the grid

At 21:46 pm on March 31st, Anhui Power Grid's first million-kilowatt coal-fired generating unit, the #5 unit of the sixth phase of the Pengengeng Tongling Power Generation Company, was successfully connected to the grid, indicating that Anhui Power Grid has entered a large capacity. Leap-forward development.

The No. 5 Unit of Anhui Fengneng Tongling Power Generation Co., Ltd. is the first high-parameter, large-capacity, low-energy-consumption, environment-friendly unit with the largest international construction contracting model in the history of power construction in China, and the first million in Anhui Province. The kilowatt ultra-supercritical large-capacity generating unit has an annual power generation capacity of 5 billion kwh after it is put into operation, which will help to further optimize the regional power supply structure, increase the capacity for external power transmission, and effectively relieve the outstanding performance of Anhui province in peak summer this year. Electricity balance problem.

Before the grid-connection, the Anhui Company Coordination Center organized the dispatching, transportation, scheduling, relay protection, automation and other professional rushed to the site ahead of schedule, strictly followed the inspection and acceptance procedures for the acceptance of the unit before the grid connection and provided grid-connected technical services to actively assist The power plant is ready for the unit to start. At the same time, it will adjust the strategy of Guanyong Copper's safe control device to ensure that the unit can operate at full capacity after being connected to the grid.

The Tongling Million Unit Construction Project was under construction by the Anhui Electric Power Construction No. 2 Engineering Company and officially started on December 18, 2008. Anhui Power Construction 2 Company established the project as a “first innovation and excellence” demonstration project, and organized and organized labor competitions such as “fighting for four months, fully fulfilling production targets during the year” and “really 160 days to ensure boiler water pressure”. The activity has effectively improved the construction technology and quality management of millions of units, as well as the safety and civilized construction management level, accelerated the progress of the project, and created vital groups. Fully applying new processes, new technologies, new solutions, and new materials, they have overcome many technological problems such as the welding of special steels such as T23, and created a one-time pouring and forming of foundation concrete for boilers with a capacity of more than 10,000 cubic meters, and lifting and loading of chimney box-type load-bearing beams. The company has the highest weight, the largest external dimensions, the highest hoisting height, and the top-ranking performance in China, including the largest transformer installation in China and the largest cooling tower in the province.

In the construction of the project, the DZQ200 folding boom self-elevating tower crane upgrade and transformation equipment used in the construction of the cold water tower was identified by the “Anhui Science and Technology Research Achievement” of Anhui Science and Technology Department and won the “Anhui Scientific and Technological Research Achievement Award”; in 2010, China Electric Power At the launching of the QC results announcement, the QC group of the Chimney Quality Control QC team won the first prize for the outstanding results of the first place in the group.
