Title:
PHOTOVOLTAIC POWER GENERATION AND SEWAGE TREATMENT INTEGRATED DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/178969
Kind Code:
A1
Abstract:
Disclosed are a photovoltaic power generation and sewage treatment integrated device and a control method therefor. An energy consumption part of the integrated device is sequentially divided into various energy consumption systems. When the illuminance is high enough, a photovoltaic power generation system is used for full-day power supply. When the photovoltaic power generation system is weak and a municipal power grid system is supplying power normally, according to the power supply amount of the photovoltaic power generation system, the power supply ratio of the photovoltaic power generation system and the municipal power grid system is reasonably distributed according to the different energy consumption systems. When the photovoltaic power generation system is weak and the municipal power grid system is powered off, according to a liquid level height of an adjustment tank, the sequence of power supply to the different energy consumption system power supply is selected, so as to achieve sequential single power supply by the photovoltaic power generation system. By means of the described means, provided is a cooperative control mode of the photovoltaic power generation system and the municipal power grid system under different working conditions such as sufficient illumination, insufficient illumination and municipal power failure. The operation efficiency of the device is improved, and the operation energy consumption of the device is reduced.
