Problems solved by technology

When multiple commonly used centrifugal water pumps work at the same time under low light conditions, the efficiency of a single pump is very low, and sometimes it cannot even discharge water due to the head. The energy generated by the photovoltaic array is greatly wasted, which directly affects the improvement of the photovoltaic water lifting system. amount of water

Abstract

The invention discloses a photovoltaic intelligent centralized control water lifting system based on a MPPT algorithm, and a main machine fault control method, a main machine cutoff control method anda water lifting efficiency improvement method based on the system. The photovoltaic intelligent centralized control water lifting system based on the MPPT algorithm comprises a photovoltaic array, multiple drivers and multiple water pumps; the photovoltaic array is connected with the drivers; the drivers comprise a driver main machine and at least one driver slave machine; each driver is connected with at least one water pump; a photovoltaic intelligent centralized control module is used for detecting the operation conditions of the drivers; and when the photovoltaic intelligent centralized control module detects faults or breakage of the driver main machine, the driver main machine commands the next driver slave machine, connected with the driver main machine, to automatically switch toa new driver main machine. The system uses the energy generated by the photovoltaic array to the greatest extent, and effectively improves the water lifting quantity.

Description

technical field [0001] The invention relates to the technical field of photovoltaic water pumping, in particular to a photovoltaic intelligent centralized control water pumping system and a control method based on an MPPT algorithm. Background technique [0002] In the case of a large amount of water and no power grid, a single large-frequency photovoltaic water-lifting system or multiple independent low-frequency photovoltaic water-lifting systems are generally used. The energy generated by the photovoltaic array under sunlight is transmitted to the water pump through the photovoltaic water pump driver, so as to achieve the purpose of water lifting. When multiple commonly used centrifugal water pumps work at the same time under low light conditions, the efficiency of a single pump is very low, and sometimes it cannot even discharge water due to the head. The energy generated by the photovoltaic array is greatly wasted, which directly affects the improvement of the photovolt...
