Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
As introduced in the related art, the existing modular inverter needs a dc source and a power grid to perform the aging test, so that the aging test occupies more equipment resources. In addition, the energy consumption for performing the aging test is also large.
In order to solve the problems in the prior art, the embodiment of the invention provides a modular inverter aging test device and method and electronic equipment. First, the aging test apparatus for a modular inverter according to an embodiment of the present invention will be described.
The embodiment of the present invention provides a modular inverter aging test apparatus, as shown in fig. 1, the test apparatus at least includes a first inverter module 11 and a second inverter module 12, when testing, the first inverter module 11 and the second inverter module 12 need to be connected according to the following connection relationship, that is: the PV end of the first inverter module 11 is electrically connected with the PV end of the second inverter module 12; the battery terminal BAT of the first inverter module 11 is electrically connected to the battery terminal BAT of the second inverter module 12; the LOAD side LOAD of the first inverter module 11 is electrically connected to the LOAD side LOAD of the second inverter module 12; the GRID-connected terminal GRID of the first inverter module 11 is electrically connected to the GRID-connected terminal GRID of the second inverter module 12. In addition, the GRID-connected terminal GRID of the first inverter module 11 and the GRID-connected terminal GRID of the second inverter module 12 are both connected to the GRID AC SOURCE.
It should be noted that, for the PV end and the battery end of each of the first inverter module 11 and the second inverter module 12, the PV end and the battery end may be electrically connected through a converter circuit, such as a DCDC converter circuit or a DCAC converter circuit, so as to ensure that the two inverter modules operate normally.
After the connection between the first inverter module 11 and the second inverter module 12 is completed according to the connection relationship, the aging test of the modular inverter may be started. In the aging test process, the first inverter module 11 and the second inverter module 12 alternately serve as a module to be tested and a simulation module. For the module to be tested, a plurality of working modes to be tested can be sequentially executed according to a preset sequence. For the simulation module, the simulation module can execute a simulation working mode corresponding to the current working mode to be tested of the module to be tested so as to provide the test condition of the current working mode to be tested of the module to be tested. Therefore, different inverter modules in the modularized inverter can be set with different working modes, the purpose of mutual aging test is achieved, energy circulates inside the modularized inverter, and the energy-saving effect is achieved.
Through the above description, it can be found that the aging test device for the modular inverter is essentially a modular inverter, but the modular inverter needs to be configured according to the connection relationship and the test logic of the aging test.
The following describes in detail the to-be-tested operating mode of the to-be-tested module and the simulation operating mode of the simulation module.
For the module to be tested, the plurality of working modes to be tested executed by the module to be tested can comprise a first MPPT mode that a working path is from PV to a power grid, a second MPPT mode that the working path is from PV to a battery, a battery discharging mode that the working path is from the battery to the power grid and a battery charging mode that the working path is from the power grid to the battery.
For the simulation module, the simulation working mode executed by the simulation module corresponding to the working mode to be tested is as follows: the simulation working mode corresponding to the first MPPT mode is a first MPPT simulator mode with a working path from a power grid to PV, the simulation working mode corresponding to the second MPPT mode is a second MPPT simulator mode with a working path from a battery to PV, the simulation working mode corresponding to the battery discharging mode is a simulation battery charging mode with a working path from a power grid to a battery, and the simulation working mode corresponding to the battery charging mode is a simulation battery discharging mode with a working path from a battery to a power grid.
It should be noted that the essence of the burn-in test is to test the operation paths of the inverter modules in the modular inverter, i.e. the above-mentioned PV-to-grid, PV-to-battery, battery-to-grid and grid-to-battery operation paths. Because the inverter module is not connected to the PV in the above connection relationship, and the applicant finds that the inverter module has a function of simulating PV and MPPT (Maximum Power Point Tracking), a test condition can be provided for another inverter module by one inverter module in the modular inverter, so that the purpose of mutual aging test of two inverter modules in the modular inverter can be achieved.
It should be noted that if the modular inverter includes three or more inverter modules, the test can be performed according to the test logic, only any two inverter modules need to be combined into the module to be tested and the simulation module, and after the test of one inverter module is completed, the next inverter module is replaced, so that the mutual aging test of the three or more inverter modules can be completed.
In some embodiments, the preset sequence in which the module to be tested sequentially executes the plurality of working modes to be tested may be various, for example, the preset sequence may be any one of an arrangement sequence of the first MPPT mode, the second MPPT mode, the battery discharge mode, and the battery charge mode. As shown in table one, a preset sequence is provided.
Watch 1
Referring to fig. 2, it shows a flowchart of an implementation of the aging test method for the modular inverter provided in the embodiment of the present invention, the aging test method for the modular inverter is applied to the aging test apparatus for the modular inverter described above, and is detailed as follows:
In some embodiments, a certain inverter module in the modular inverter may be used as a master module in advance, and then the master module determines the delimiting identity. Specifically, the first inverter module may be set as a master control module, and thus, the first inverter module may send a third instruction for setting an identity to the second inverter module, so as to set the second inverter module as a simulation module.
In some embodiments, the simulation module may obtain the current working mode of the test module to be tested in a plurality of ways.
For example, the module to be tested may send a first instruction to the simulation module, where the first instruction carries a target working mode to be tested to be executed by the module to be tested. Therefore, after receiving the first instruction, the simulation module acquires the target to-be-tested working mode to be executed by the test module, and since the target to-be-tested working mode to be executed is executed immediately, the target to-be-tested working mode to be executed is the current to-be-tested working mode of the simulation module, so that the simulation module can determine the target to-be-tested working mode as the current to-be-tested working mode of the test module. In addition, the simulation module needs to notify the module to be tested, for example, a second instruction is returned to the module to be tested to notify the module to be tested that the module to be tested successfully receives the first instruction, and notify the module to be tested to execute the target working mode to be tested.
For another example, the simulation module may obtain the current to-be-tested operating mode of the test module through port information of the to-be-tested module, where the port information includes electrical states of the PV end, the battery end, the load end, and the grid-connected end, such as state signals of a voltage value or a current value. Therefore, the simulation module can acquire the port information of the module to be tested and then determine the current working mode to be tested of the test module according to the port information.
Specifically, the preset corresponding relation records a simulation working mode corresponding to any working mode to be tested. For example, when the current to-be-tested working mode of the test module is the first MPPT mode, the simulation module determines the first MPPT simulator mode as the target simulation working mode. And under the condition that the current working mode to be tested of the test module is the second MPPT mode, the simulation module determines the second MPPT simulator mode as a target simulation working mode. And under the condition that the current working mode to be tested of the test module is a battery discharging mode, the simulation module determines the simulation battery charging mode as a target simulation working mode. And under the condition that the current working mode to be tested of the test module is a battery charging mode, the simulation module determines the simulated battery discharging mode as a target simulated working mode.
Therefore, the module to be tested and the simulation module can sequentially complete the aging test of the module to be tested according to the preset sequence. And then, the module to be tested and the analog module can exchange identities, and then the aging test of the other inverter module is completed according to the test logic.
Taking the first inverter module as the module to be tested as an example, when the first inverter module sequentially executes according to the preset sequence to complete the plurality of working modes to be tested, the first inverter module may send a fourth instruction to the second inverter module, so that the second inverter module serves as the module to be tested, thereby performing the aging test on the second inverter module.
In an embodiment of the present invention, a modular inverter aging test apparatus at least including a first inverter module and a second inverter module is provided, where the first inverter module is correspondingly connected to a PV end, a battery end, a load end, and a grid-connected end of the second inverter module, and both the grid-connected end of the first inverter module and the grid-connected end of the second inverter module are connected to a power grid. When the aging test is carried out, the first inverter module and the second inverter module in the aging test device of the modular inverter are alternately used as the module to be tested and the simulation module, the module to be tested sequentially executes a plurality of working modes to be tested according to the preset sequence, and the simulation module executes the simulation working mode corresponding to the current working mode to be tested of the module to be tested so as to provide the test condition of the current working mode to be tested of the module to be tested, so that the two inverter modules in the modular inverter can be used for carrying out the mutual aging test. Therefore, when the aging test device of the modular inverter is used for aging test of the modular inverter, the direct current source does not need to be connected, and therefore equipment resources occupied by the aging test are greatly saved.
Embodiments of the present invention also provide a computer program product having a program code for performing the steps of any of the above described modular inverter aging test method embodiments, such as steps 210 to 230 shown in fig. 2, when the program code is run in a corresponding processor, controller, computing device or terminal.
