System for lifting water through solar photovoltaic and making redundant electricity get on grid

Abstract

The invention discloses a system for lifting water through solar photovoltaic and making redundant electricity get on a grid. The system comprises a mechanical and electrical water lift system and a redundant electricity get-on-grid system. The redundant electricity get-on-grid system comprises a solar photovoltaic cell board, a convergence box, an inverter, a positive displacement pump, a valve body, a boosting station, a data storage and analysis library, a controller, an online industrially-controlled display platform, a data output end and a printer. The mechanical and electrical water lift system is composed of a water inlet pipe, a water pumping pool, a bottom valve, a water pumping pipe, a positive displacement pump, a motor, a power distribution control cabinet, a water conveying pipeline and a high-position water pool. The electricity demand of the photovoltaic water lift system is automatically judged by the system, and redundant electricity gets on the national grid or local grid through the boosting station; the system automatically collects and arranges the water pumping amount, energy consumption, running working conditions, failures, historical data accumulation and other big data through the intelligent control system, the production working conditions and production benefits of the water lifting system are automatically evaluated through big data analysis, the running optimization scheme is automatically generated, and the use effect is good.

Description

technical field [0001] The invention relates to a technical field of electromechanical water lifting equipment, in particular to a solar photovoltaic water lifting system and surplus power grid connection system. Background technique [0002] The electromechanical water lifting system includes water inlet pipe, water intake tank, bottom valve, water intake pipe, positive displacement pump, motor, power distribution control cabinet, water pipeline and high-level pool. Provide 380v power supply, start and stop the pump system according to the water level of the high level pool, stop the pump system when the liquid level is high, and start the pump system when the liquid level is low. Although the electromechanical water lifting system meets the needs of people, the electromechanical water lifting system needs to provide electric energy through the high-voltage power grid and transformers, and the cost of power transmission and transformation is high; the electromechanical wate...

Problems solved by technology

Although the electromechanical water lifting system meets the needs of people, the electromechanical water lifting system needs to provide electric energy through the high-voltage power grid and transformers, and the cost of power transmission and transformation is high; the electromechanical water lifting system has high head, large water lifting capacity, high energy consumption, and high The high energy consumption cost makes the operation cost of electromechanical water lifting high. Although electromechanical water lifting systems have been built in many places, the water lifting stations are abandoned because they cannot bear the high operating costs. Start and stop the machine pump system, complex operation
