Component cleanliness monitoring device and monitoring method

Abstract

The invention provides a component cleanliness monitoring device comprising a reference component, a test component, a first acquisition module, a second acquisition module, a power calculation module, a measurement module and a display module. The reference component, the first acquisition module and the power calculation module are connected to lead out the current and the voltage of the reference component, and the power of the reference module is calculated. The power calculation module is connected in series with the measurement module and the display module. The measurement module performs operation of the power of the reference component inside the power calculation module and the power of the test component. The test component and the reference component are compared, whether the cleanliness of the test component is low and cleaning is needed is judged according to the comparison result, and the external environment in which the test component is located is consistent with other photovoltaic panels environments of the power station so that whether the photovoltaic panel of the power station needs to be cleaned can be reflected by the test component. According to the component cleanliness monitoring device and monitoring method, the detection result is clear and accurate, and the identification error caused by the subjective judgment can be avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power station maintenance, in particular to a module cleanliness monitoring device and a monitoring method. Background technique [0002] The power generation of photovoltaic power plants directly affects the operating income of photovoltaic power plants. At present, the main factors affecting the power generation of photovoltaic power plants are: 1. Equipment failure rate; 2. Weather factors (it is difficult to solve the impact of weather factors on power generation at present); 3. , Cleanliness of components. [0003] The loss caused by the failure of the equipment can be avoided by replacing the equipment and good maintenance to avoid the same problem in the future. The cleanliness of photovoltaic modules is currently the most influential factor on the power generation of photovoltaic power plants. At present, each power station judges the timing of cleaning modules mainly as follows: 1. ...

Problems solved by technology

[0004] Although the above two judgment methods have their own judgment standards and operation and maintenance experience, they both have a drawback. The decision-making based on people's subjective wishes can increase operating income by hundreds of thousands or hundreds of thousands. , the uncertain factors and economic losses caused by subjective assumptions cannot be estimated
