A system that combines several comprehensive utilization water conservancy hubs or public buildings (such as reservoirs, etc.) with special buildings (such as irrigation canal heads, hydropower plants, ship locks, etc.) through rivers and water channels. It is formed by the development and utilization of water resources in a river basin or the development and utilization of water resources across river basins. Its function is to be able to fully consider the water needs of various sectors of the national economy, rationally develop and utilize water resources, divert and divert water across river basins, adjust surplus and shortages, and balance supply and demand. After using the frequency inverter, the water pump can soft start and stop to reduce the mechanical impact of the equipment, extend the service life of the equipment, and reduce the maintenance cost of the equipment.
