en.Wedoany.com Reported - Unit 1 of Baihe Hydropower Station, operated by Beijing Hydropower Company, recently successfully passed a 15-day trial operation assessment, completing all tests on July 16, 2026, and officially transitioning into the commissioning preparation phase.
The 15-day trial operation assessment is regarded as the most rigorous real-world test before a unit is officially put into operation. This test comprehensively evaluated the quality of the unit's manufacturing, installation, and commissioning. During the trial operation, key operating parameters of Unit 1, including vibration, shaft deflection, and bearing temperature, remained within optimal ranges. The unit's start-stop success rate, protection device activation rate, and correct operation rate all reached 100%. All systems operated stably and smoothly, with overall performance meeting design and specification requirements. The equipment's reliability and automation level withstood prolonged, high-intensity testing.
To ensure the unit entered the trial operation assessment phase on schedule and with high quality, Beijing Hydropower Company coordinated resource allocation, developed a detailed schedule, and strictly followed the full set of commissioning procedures. Dozens of preliminary specialized tests were completed, including generation mode, pumping mode, mode transition, and grid-related tests. These preparatory efforts eliminated various potential equipment defects and operational risks in advance, allowing the equipment to face the assessment in optimal condition, laying the foundation for Unit 1 to pass the 15-day trial operation assessment in a single attempt.
The success of Unit 1's trial operation assessment has accumulated valuable experience for subsequent work and provided a practical reference model. Beijing Hydropower Company stated that, building on this success as a new starting point, it will strictly adhere to safety control baselines, efficiently advance the commissioning and trial operation assessment of Unit 2, and fully ensure flood control and drainage at Miyun Reservoir, the capital's drinking water supply, and regional power stability.
