Description
Technical field
The utility model belongs to technical field of solar utilization technique, particularly electric grid-connected system more than a kind of photovoltaic water-raising.
Background technology
Solar energy have the restriction of clean, No Assets region, concerning the mankind forever without good characteristics such as exhaustions, be more and more subject to the favor of people, wherein solar energy photovoltaic utilization and the sunlight technology that is directly changed into electric energy by photovoltaic device is especially noticeable.
Along with developing rapidly of China's industrialized agriculture, all parts of the country establish photovoltaic water-raising system as required for agricultural irrigation etc.
At present, photovoltaic water-raising system does not utilize solar energy electricity completely, and when solar light irradiation abundance, electricity exceedes water-raising system rated power, and this part unnecessary electricity does not utilize; When water-raising system does not have in harness time, whole solar power system electricity does not utilize completely, causes the wasting of resources; Or when the lower electricity of solar energy irradiance ratio is not enough to drive water-raising system, now electricity does not also utilize and wastes.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of photovoltaic to meet to pump up water and can make full use of electric grid-connected system more than the grid-connected photovoltaic water-raising of remaining electricity.
The technical solution of the utility model is achieved in that electric grid-connected system more than a kind of photovoltaic water-raising, it is characterized in that: comprise solar module, power adjustment system, photovoltaic water pump controller, water-raising system and combining inverter, the electric energy output end of described solar module is connected with power adjustment system, the output of described power adjustment system is connected with photovoltaic water pump controller and combining inverter respectively, described photovoltaic water pump controller is connected with water-raising system, and described combining inverter is connected with electrical network.
Electric grid-connected system more than photovoltaic water-raising described in the utility model, described in it, power adjustment system comprises detection commutation circuit, the output of described power adjustment system has two-way interface, wherein photovoltaic water pump controller is received on a road, combining inverter is received on another road, and described solar module electricity is used for water-raising system and/or input electrical network by the allotment of power adjustment system.
The utility model, by the setting of power adjustment system, can according to circumstances effectively be planned solar module electricity and distribute, make it can meet the requirement pumped up water for irrigation, take full advantage of again unnecessary solar energy resources.
Accompanying drawing explanation
Fig. 1 is system flow chart of the present utility model.
Mark in figure: 1 is solar module, and 2 is power adjustment system, and 3 is photovoltaic water pump controller, and 4 is water-raising system, and 5 is combining inverter, and 6 is electrical network.
