en.Wedoany.com Reported - The reverse power transmission for Unit 1 of Yanchang Petroleum's Wuxue 2×660MW coal power project in Hubei has been recently completed. The project is undertaken by Shandong Electric Power Construction No.1 Company. The achievement of this milestone has created conditions for subsequent motor trial runs, boiler full-load startup, and grid connection of the unit.

During construction, the project team faced challenges such as high construction pressure during the rainy season and delays in equipment and material delivery. By dynamically reviewing construction plans daily and strengthening multi-party coordination, the team successfully resolved bottlenecks in equipment transportation and line installation, ensuring smooth progress for the reverse power transmission preparations. The reverse power transmission operation lasted 13.5 hours. The project team sequentially completed the 220kV GIS startup standby transformer interval and startup standby transformer impact tests, followed by power-on operations for the 220kV booster station, startup standby transformer, and related primary and secondary equipment of the 10kV system. Ultimately, the 10kV A/B bus sections were successfully energized in a single attempt. After power-on, the system operated stably, with centralized control data for all energized equipment showing normal readings, accurate signal indications, and 100% electrical protection coverage.

The project has been designated as a key energy project in Hubei's "14th Five-Year Plan." It utilizes the deep-water shoreline resources of the Yangtze River and is designed to generate over 6.6 billion kWh of electricity annually, along with 4.5 million tons of industrial heating steam per year. Once operational, the project will fill 15% of the power gap in the eastern Hubei region, including Huanggang and Huangshi, while providing heat supply for the port industrial park. Additionally, by shutting down scattered small coal-fired boilers in the park, it will reduce coal consumption by more than 120,000 tons annually, supporting the green upgrade of the park's fine chemical and new materials industries and optimizing the province's energy distribution pattern.
