NB/T 10352-2019Code for Energy Efficiency Design of Hydropower Project (English PDF)

2.0.1 Energy consumption during the operation period

During the operation of the hydropower project, the main production equipment, auxiliary production equipment, auxiliary production and The total energy consumption of living facilities.

2.0.2 Annual comprehensive energy consumption

Annual comprehensive energy consumption annual comprehensive energy consumption.

The equivalent value or equivalent value of energy consumption during operation is the energy consumption converted to standard coal.

2.0.3 Service power consumption ratio

Electric power consumption ratio of station service system service power consumption ratio The annual power consumption of the auxiliary production equipment of the power station unit and the auxiliary production and living equipment of the power station accounts for the output power generation of the unit The ratio of the sum of the pumped water input power.

2.0.4 Energy consumption per unit of added value

Energy consumption per added value energy consumption per added value.

The energy consumed to produce or create the added value of a unit of measurement is the value and increase of comprehensive energy consumption. The ratio of the values.

4.1 Project planning

4.1.1 The selection of development methods in river hydropower planning should be based on rational use of hydropower resources.

4.1.2 Determining the reasonable construction scale of hydropower projects should include energy-saving comparison and selection related content.

4.1.3 Under the premise of meeting the development tasks, the characteristic water level and operation mode of the reservoir should be reasonably determined to improve the hydropower resources Utilization rate.

4.2 General layout of the project

4.2.1 The general layout of the project should be conducive to energy saving and consumption reduction, and the comparison and selection of layout schemes should include the relevant content of energy saving and consumption reduction.

4.2.2 The general layout of the project should be reasonably laid out, compactly laid out, occupy less land, and have a small footprint, provided that the functional requirements of the hub are met.

The process is small, and it is convenient for operation, maintenance and management.

4.2.3 The positions of booster stations, switch stations, and outlet yards should be combined with generator voltage buses, high-voltage lead wires, and high-voltage power distribution The technical and economic comparison and selection of installations and civil engineering are comprehensively determined.

4.2.4 When conditions permit, artesian drainage tunnels should be set up in underground caverns.

6.1 Hydraulic machinery

6.1.1 The selection of hydraulic turbines and pump turbines should be based on the operating head and installed capacity of the power station to select a reasonable model and a single unit Capacity, select better efficiency indicators under the premise of reasonable parameters, and use reasonable structural styles and high-quality materials.

The energy efficiency indicators of large-scale units should be compared and demonstrated.

6.1.2 The energy-saving design of the bridge crane of the main building shall meet the following requirements.

1 The number and type of units should be determined comprehensively according to the layout of the plant, the number of units and the lifting method. It is advisable to select low energy consumption, A highly mobile solution.

2 When the auxiliary hook capacity is relatively large, an electric hoist with a smaller weight should be arranged under the beam.

3 Frequency conversion speed regulation should be adopted for the lifting and operating mechanism.

6.1.3 The technical water supply system shall meet the following requirements.

1 The technical water supply plan should be reasonably determined according to the operating head of the power station.

2 Under the premise that conditions are available and the technology and economy are relatively reasonable, gravity flow, gravity pressure reduction or roof water intake should be adopted. Wait for the water supply program.

3 For units with high water head or muddy rivers, after determining that the technology is feasible and economically reasonable, a closed cycle can be used Water cooling method.

6.1.4 The pipe diameter of the technical water supply system should be determined according to the economic flow rate. Reduce piping loss through optimized layout, Under the conditions of sufficient conveying medium and pressure level, pipes with lower friction should be selected.

6.1.5 The selection of oil, gas, and water system equipment should meet the following requirements. […]
