Abstract
The utility model discloses a parameter tester installation structure in a grid solar photovoltaic plant, which is capable of measuring with accuracy the real-time irradiance and temperature of a solar photovoltaic component, wherein, a solar irradiance tester is installed on the light-induced plane of the solar photovoltaic component in the photovoltaic plant, and a temperature tester is encapsulated in the solar photovoltaic component. The utility model has the advantage of measuring the extent of irradiation accepted by the surface of the solar photovoltaic component and the temperature inside the solar photovoltaic component in a real-time manner, thereby providing a reliable basis for the accurate measurement of the instantaneous generated output of the grid photovoltaic plant.
Description
Technical field
The utility model relates to the solar energy power generating field, refers more particularly to the mounting structure of parameter tester in a kind of parallel networking type solar photovoltaic power station.
Background technology
Along be becoming tight energy resources supply day, ecological deterioration increasingly sharpens, the dynamics that energy-saving and emission-reduction are carried out by country continues to increase, parallel networking type solar photovoltaic power station has obtained Preliminary Applications at home.
Parallel networking type photovoltaic power station can be converted into direct current by solar photovoltaic assembly with solar irradiation, is connected to the grid after combining inverter changes into alternating current.The power generation performance of parallel networking type photovoltaic power station is the important technological parameters of photovoltaic plant, at present can only (standard test condition comprises: solar irradiance 1000W/m at standard test condition with the monolithic photovoltaic module that adopted
2, 25 ℃ of the inner photovoltaic battery temperatures of solar photovoltaic assembly, air quality AM1.5) down the summation of peak power represent.Because standard test condition can only could form by strict control in the laboratory, photovoltaic plant integral body can not be put into its power generation performance of checking under the breadboard standard test condition, and environmental parameter such as solar irradiance, photovoltaic module cell temperature constantly changes in the practical application, make the generated output of each time point of parallel networking type photovoltaic power station all change, thereby adopt the summation of photovoltaic module peak power under standard test condition to verify that there is more deficiency in the method for photovoltaic plant.
People are making great efforts to research and develop the verification method and the device that can accurately calculate generation power of interconnected photovoltaic power station at present, parameters such as real-time solar irradiance that main dependence records and environment temperature are calculated, but also there is following shortcoming in these measurement data: one, the irradiance difference that the solar photovoltaic assembly surface is accepted in irradiance tester data presented and the photovoltaic plant is bigger, two, the temperature measuring device working temperature and the solar photovoltaic assembly temperature inside difference that show be bigger; Thereby the instantaneous generated energy error that its output system shows is bigger, makes and has no idea when the power plant project final acceptance of construction to confirm whether the generated energy of photovoltaic plant meets the requirements.
The utility model content
Technical problem to be solved in the utility model is: the mounting structure that parameter tester in the parallel networking type solar photovoltaic power station of a kind of real-time irradiance that can accurately test out solar photovoltaic assembly and temperature will be provided.
For addressing the above problem, the technical solution adopted in the utility model is: the solar irradiance tester is installed on the same plane of sensitive surface of solar photovoltaic assembly in the photovoltaic plant, temperature measuring device is encapsulated in the inside of solar photovoltaic assembly.
The utility model has the advantages that: can measure irradiance and the solar photovoltaic assembly temperature inside accepted on the solar photovoltaic assembly surface in real time, thereby provide reliable foundation for the instantaneous generated output that accurately calculates parallel networking type photovoltaic power station.
