Description
Technical field
The invention belongs to a kind of technology application in solar energy power generating field, particularly
a kind of solar module topological structure converting means with isolating device.Use the present invention compared with conventional solar module topological structure converting means, when the topological structure of its solar module switches, the rush of current that battery component bears too high reverse voltage and reduces inverter can be avoided.
Background technology
The solar photovoltaic generation system of conventional solar photovoltaic assembly primary topology, can convert according to the topological structure of the intensity of sunlight to battery component and adjust, make the output voltage of battery component can reach the input requirements of inverter, the energy output of solar photovoltaic generation system can be improved.But when solar photovoltaic battery component topological structure switches, battery component and inverter need first to disconnect, then topological structure is changed, reconnect to inverter again, disconnect moment inverter to lose that DC exports to, inverter be instantaneously zero, to reconnect and moment is loaded on ceiling voltage suddenly, rush of current is very large, to steadily generating is unfavorable.
Through retrieval, in existing solar photovoltaic generation system, also not similar with the present invention invention having the solar module topological structure converting means of isolating device.
Summary of the invention
The object of this invention is to provide
a kind of solar module topological structure converting means with isolating device, this device, by organizing the variable solar photovoltaic battery component integrated unit of topological structure, forms respectively by being connected in parallel after isolating diode more again.Owing to having isolating diode, if the integrated unit output voltage after switching is higher, owing to there being diode-isolated, can not have an impact to other integrated units.Therefore the topological structure often organizing solar photovoltaic battery component can switch separately, and during one group of switching, remaining one group also generates electricity in networking to many groups, and generating can not be interrupted, and switches the rush of current of inverter less.
The object of the invention is to realize by the following method:
"
a kind of solar module topological structure converting means with isolating device", it comprises solar module integrated unit (1), (2) ... (n) of many group primary topology, isolating diode (D1), (D2) ... (Dn), inverter (N1).It is characterized in that: the solar module integrated unit (1) of primary topology, (2) ... (n), be connected respectively to isolating diode (D1), (D2) ... (Dn) positive pole, isolating diode (D1), (D2) ... (Dn) negative pole links together, then the electrode input end of inverter (N1) is connected to, the solar module integrated unit (1) of primary topology, (2) ... n the negative pole of () links together, be then connected to the negative input of inverter (N1).
The present invention adopts unique syndeton, by in parallel for the solar components integrated unit organizing identical primary topology more, the topological structure respectively organizing solar module during operation switches in turn, and the rush of current to inverter when just can reduce switching, improves the stability of output voltage.But when switching in turn, battery component after switching moment in parallel with the battery component do not switched, the battery component that number in parallel is lower will bear the high voltage that the higher battery component of number in parallel produces, and this voltage likely exceedes reverse voltage that the lower battery component of number in parallel can bear and causes battery component to damage.The present invention adds an isolating diode at the output of every Battery pack assembly, and then in parallel, bears too high reverse voltage, to protect battery component by isolating diode.
Use this device, the topological structure of the solar module integrated unit of each group of primary topology can switch in turn, when one group of integrated unit and inverter disconnect, another Battery pack assembly is also connected with inverter, continue to generate electricity by way of merging two or more grid systems, generating can not be interrupted, and switches the rush of current of inverter less, and can not exert an adverse impact to assembly.
