Problems solved by technology

[0003] In the prior art, the commonly used monitoring system mainly realizes the remote monitoring of the power signal of the solar photovoltaic power station. Specifically, it only displays the different data of the power signal in the same window without directly forming a comparison result; The system can monitor the working conditions of the photovoltaic power station according to the current change rate in the strings, but this kind of monitoring system is easy to cause when there is interference from the outside world, such as when the solar cell strings are blocked by objects or clouds passing by, etc. Errors in monitoring results

Embodiment Construction

[0052] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0053] Since the solar cell is the basic unit of the solar photovoltaic power station, multiple solar cells are connected in series to form a solar cell string. For different solar photovoltaic power stations, the arrangement of the solar photovoltaic array may be quite different. The number of strings is large, and one or more combiner boxes can be used to combine the power generation of the solar cell strings. Therefore, ensuring that each solar cell string and the combiner box can work normally is the prerequisite for ensuring the normal operation of the solar photovoltaic power station.

[0054] Such as figure 1 As shown, it is a part of a solar photovoltaic power station provided by an embodiment of the pre...

Abstract

The invention discloses a method and system for monitoring the working state of a solar photovoltaic power station, and belongs to the technical field of solar photovoltaic power generation. Firstly, abnormalities are detected through the current change rate and the sunlight intensity change rate, fault wrong declaration is eliminated through checking of current values of adjacent or close input ends, and the abnormalities are detected. The monitoring method is high in monitoring accuracy.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a method and system for monitoring the working state of a solar photovoltaic power station. Background technique [0002] There are many connections between the solar photovoltaic cell array and the inverter in the solar photovoltaic power station, and the line loss is large, and there are many types of solar panels used in the industry, and the parameters of the components vary greatly. For different design schemes, there will also be Different forms of inverters are used, so that in practical applications, according to different projects, the arrangement of solar photovoltaic arrays is various. Based on the fact that the working characteristics of each string in the photovoltaic array are very different, it is difficult to delineate a certain value range for the working state of the solar cell string (or called the string) based on the characteristic...
