1. If the power system fails, the power station can consider shutting down directly. If there is water leakage in the guide vane, the valve can be closed to reduce the waste of water in no-load operation.
2. The power factor of the generator is increased to 0.85—0.95, reducing the investment of the generator.
3. The insulation material of the generator is selected as Class B to reduce the investment of the generator.
4. Generators below 1250 kilowatts can use low-voltage units, which reduces the investment in generators and electrical equipment and reduces operation and maintenance costs.
5. Reduce the strong excitation multiple of the excitation. Reduce the investment in excitation transformers and excitation components.
6. Use the oil source of the high oil pressure governor to reduce the pressure and supply it for braking and rotor lifting. The oil system and the medium and low pressure gas system can be cancelled. Reduce oil and gas line equipment.
7. The valve uses an electric operating mechanism. Reduce the investment in the valve operating mechanism and simplify the valve control loop. Reduce management and maintenance costs.
8. The runoff power station adopts constant high water level operation mode. Make efficient use of water resources.
9. Completely configured and high-quality automation components. Realize no one on duty.
10. Use multi-functional and highly integrated intelligent devices to reduce secondary equipment configuration.
11. Promote the concept of debugging, operation and maintenance-free secondary equipment. Let power station operation and management personnel have decent and happy jobs.
12. Realize socialization of power station operation and maintenance. It can quickly improve the overall operation and management level of the small hydropower industry.
13. The low-voltage unit adopts an integrated control protection screen to enable unattended operation.
14. The low-pressure unit adopts a new type of microcomputer high oil pressure fully automatic speed regulator for the low-pressure unit. It can provide basic automation equipment for unattended operation.
15. The brushless excitation mode can be used for units with a single unit of less than 10,000 kilowatts. The excitation equipment can be simplified and the excitation transformer can be eliminated.
