1 Basic technical requirements for micro hydroelectric power generation equipment, this standard is in accordance with GB 17532
NY664-2003
This standard is proposed and coordinated by the Science and Technology Department of the Ministry of Agriculture, and the drafting units of this standard are: Nanjing Agricultural Machinery Research Institute of the Ministry of Agriculture, Micro Hydropower Equipment Quality Supervision and Inspection Test Center of the Ministry of Agriculture. This standard is mainly composed of individuals, and the implementation of this standard is entrusted to the Ministry of Agriculture Water Supply Equipment Quality Supervision and Inspection Test Center.

NY664-2C03
Micro hydroelectric power generation equipment is independent of the high-voltage grid, and its power load can vary between 0-100% of the rated load. If there is a control, the average output voltage and power of the unit are as unstable as possible; the unit startup and sequence recording causes electrical appliances or plastics. The controllers of micro hydroelectric power generation equipment are divided into two major categories: 1. Change the input energy (control the water intake to make the input energy correspond to the electricity demand) 2. Change the transfer coefficient of the system (change the system efficiency); 3. Keep the total power load basically unchanged [When the power consumption decreases, connect a similar load or the total load remains basically unchanged:, because the second method can only stabilize the pressure but not the pregnancy, the use of the protective function is limited, the scraper is moving, and the machine has no protection load and should not be used in the micro-double power; the first method must activate the water control mechanism, and its structure is together with the small turbine, and cannot be used as an independent product. The third method has both pressure and heat, and has start-up and shutdown protection. It has sufficient protection function and can be used as an independent product. The control method can be divided into two types: electrical type and electronic type. The electrical type has a high failure rate and cannot implement high-level control. Products higher than this will be eliminated. The electronic type controller is a product that appeared in the late SC period. It has not been developed since then. It is used as an independent component to supply electronic controllers for micro-hydropower generation equipment with a power of 100kW and below. In order to ensure the power supply ratio of the machine, this standard is specially formulated. This standard is based on the research, production, decommissioning and development of my country's recent hydropower generation equipment and its electronic type manufacturing equipment.
