GB/T 44273-2024 in English

1. General requirements

The core goal of the hydropower project operation management specification is to ensure the safe, efficient and sustainable operation of the project. According to GB/T 44273-2024, the operation management unit needs to formulate corresponding management systems and technical regulations based on the characteristics of the project and the actual operation situation. These systems should include:

• Operation management system
• Operation procedures
• Emergency plan
• Annual safety production plan

2. Operation management of hydraulic structures

Hydraulic structures are the core facilities of hydropower stations, and their safety is directly related to the stability and safety of the entire project. The following are the specific requirements for hydraulic structures in the specification:

2.1 Safety monitoring

The operation management unit must establish a complete safety monitoring system, including the following:

• Monitoring items: displacement, tilt, cracks, etc.
• Monitoring frequency: Determined according to the project stage and risk level.
• Data processing: Regularly analyze monitoring data and evaluate the safety status of the building.

3. Equipment and facility operation management

3.1 Monitoring and inspection

Monitoring and inspection of equipment and facilities are key links to ensure their normal operation. Specification requirements:

• Real-time monitoring using a computer monitoring system.
• Periodic inspections are carried out, and abnormalities are handled promptly.

3.2 Operation and control

The start-up, shutdown and operation of the equipment must strictly comply with relevant regulations. For example:

• The start and stop procedures of the turbine must comply with the DL/T 710 standard.
• The operation of the gates and flood discharge facilities must be carried out according to the dispatching instructions.

4. Management of the Reservoir and Project Areas

4.1 Management of the Reservoir Area

The focus of reservoir area management is:

• Monitor the stability of the reservoir bank slope.
• Regularly clean up floating objects and garbage.
• Carry out ecological monitoring and protection work.

4.2 Management of the Project Area

Activities within the project protection area must be strictly controlled to avoid harm to the hub buildings. For example:

• Dangerous activities such as sand mining and blasting are prohibited within the protection area.
• Regularly inspect the boundaries and facilities of the project area.

5. Dispatching Management

5.1 Hydrological and Meteorological Observation

Hydrological and meteorological data are the basis for dispatching decisions. Specification requirements:

• Establish a sound automatic water situation observation and reporting system.
• Develop a flood forecasting plan based on the characteristics of the river basin.

5.2 Flood Control Dispatching

Flood control dispatching is an important part of ensuring downstream safety. Specific requirements include:

• Prepare an annual flood season dispatching and operation plan.
• Obey the unified command of the flood control department.

6. Safety, Health and Environmental Management

6.1 Safety and Emergency Management

Operating units need to establish and improve safety management systems, including:

• Carry out safety inspections regularly.
• Develop emergency response plans and organize drills.

6.2 Occupational health management

Occupational health is an important part of protecting the rights and interests of employees. Regulatory requirements:

• Regularly test occupational disease hazards in the workplace.
• Provide employees with protective equipment that meets standards.
