Abstract

The invention relates to a portable self-driven photovoltaic grid connected detection apparatus and method. The portable self-driven photovoltaic grid connected detection apparatus includes a changingresistance adjusting circuit, a voltage sampling module which is connected to a detected line through the changing resistance adjusting circuit for sampling the voltage data, a current sampling circuit which is connected to the detected line through the changing resistance adjusting circuit for sampling the current data, a control module which is connected to the voltage sampling circuit and thecurrent sampling circuit for processing the voltage data and the current data, and a sensor module which is connected to the control module for measuring the radiant quantity data. Compared with the prior art, the portable self-driven photovoltaic grid connected detection apparatus measures the radiant quantity of sunlight by connecting an external sensor device, and processes the synchronizationof the internal digital-analog circuit through a pulse disturbance processing circuit, and at the same time the pulse information carries the external environment parameter auxiliary trigger function.

Description

technical field [0001] The invention relates to a detection device, in particular to a portable self-driven photovoltaic grid-connected detection device and method. Background technique [0002] In the photovoltaic grid-connected detection project, there are two detection contents, DC power quality detection and power evaluation detection. The traditional detection method is to use multiple instruments for detection and carry out step by step. Such a step-by-step test will lead to deviations in data results. At the same time, when multiple instruments are tested, it usually requires AC power on site, which is very difficult to achieve in remote photovoltaic power plant sites. Moreover, it is inconvenient and expensive to carry multiple instruments. [0003] In addition, Chinese patent CN204287338U discloses a new wind power and photovoltaic grid-connected detection comprehensive test device, including an AC grid simulation device, a first transformer, a reactor combination,...
