Problems solved by technology
[0005] Although this document discloses the test method for the power generation of photovoltaic modules, the test process only relies on the inverter to test and obtain data. The accuracy of the test data is poor, and it is difficult to compare or compare the test data.
It is impossible to obtain the status of the standard power generation efficiency under the current power generation environment, but only to obtain the currently tested data of the component board
However, it is impossible to conduct comprehensive evaluation tests on newly installed power stations or power stations installed and operated for several years

The invention provides a test device for outdoor high-precision photovoltaic power station detection and calibration. A standard photovoltaic power generation efficiency test component is installed ina photovoltaic power station to be tested. A test device slave is connected with the standard photovoltaic power generation efficiency test component, and a DC transmitter 1 and a DC transmitter 2 are connected between a photovoltaic power station and the DC side of an inverter. An AC transmitter 1 and an AC transmitter 2 are connected between the AC side of the inverter and a power distributiondevice of the photovoltaic power station. A test device master is used for obtaining test data parameters of the standard photovoltaic power generation efficiency test component through the slave. Data information of a DC port and an AC port of the photovoltaic power station is obtained by the AC transmitters and the DC transmitters, data parameters of the photovoltaic power station are calculated, and the current state of photovoltaic power station is analyzed. In this way, the power generation capacity of photovoltaic power panels to be tested of the power station can be quickly known, and the power generation efficiency of the photovoltaic power station can be systematically evaluated.
Description
technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a testing device for detection and calibration of an outdoor high-precision photovoltaic power station. Background technique [0002] At present, the photovoltaic market is huge, and photovoltaic technology develops relatively rapidly. It is often possible to develop photovoltaic power generation products with better quality and perfect performance. The power generation capacity of photovoltaic power generation products is one of the important indicators for judging the performance of photovoltaic power generation products. It is an important factor for whether it can be recognized in the actual power station operation. At present, the power generation efficiency of photovoltaic power generation products can be obtained by testing the power generation capacity of photovoltaic power generation products. For example, in the power test and power generation test of photo...
