Description

TECHNICAL FIELD

[0001] The utility model relates to PVT test technical field, concretely is a kind of comprehensive performance testing device for PVT system. BACKGROUND

[0002] PVT system includes solar photovoltaic function and solar water heating function. The performance indicators for the above-mentioned two functions are photoelectric conversion efficiency and collector efficiency. For solar photovoltaic photoelectric conversion efficiency, solar radiation, temperature, voltage, current and electric power need to be detected, and the photoelectric conversion efficiency is calculated. For solar water heating collector efficiency, solar radiation, temperature, flow, voltage, current and electric power need to be detected. The performance indicators for the whole PVT system need to be calculated based on all the detection data.

[0003] Based on the above detection requirements and targets, there are mainly two types of existing detection equipment. One is to install independent sensors (matching data acquisition storage respectively) at the corresponding positions of the PVT system to test various parameters, and the test data is stored locally. After detection, the data needs to be exported for centralized analysis. The second is to use solar photovoltaic system testers and solar water heating testers that integrate sensors. The testers are installed independently, the test data is stored independently, and after detection, the data needs to be exported for centralized analysis. The following defects exist:

[0004] 1. Inconvenient to carry: The existing detection equipment, whether using independent sensors or solar photovoltaic system testers and solar water heating testers that integrate sensors, needs to be installed separately at the corresponding positions of the PVT system, which leads to the problem of inconvenient to carry.

[0005] 2. Data cannot be monitored in real time: When using independent sensors for detection, the data during the test process cannot be monitored in real time, and the data needs to be exported for centralized analysis after detection, which limits the real-time monitoring and rapid response of the performance of the PVT system.

[0006] 3. Test results need to be processed independently: Since the data is stored independently, the data needs to be exported for centralized analysis after detection, which increases the workload and complexity of data processing.

[0007] 4. Repeated investment in sensors: When using solar photovoltaic system testers and solar water heating testers that integrate sensors, there is a repeated setting of sensors, which not only increases the cost, but also causes waste of resources.

[0008] 5. Inefficient and high cost: Due to the need for separate processing and analysis of data and repeated investment in sensors, the detection process is inefficient and high cost.

[0009] 6. Inconvenience in use: the existing detection equipment has inconvenience in use, such as the need for multiple export and centralized analysis of data, and the repeated setting of sensors, which increases the complexity of operation.

[0010] 7. Unable to perform real-time calculation and monitoring of the performance indicators of the PVT system as a whole: due to independent storage and processing of data, real-time calculation and monitoring of the performance indicators of the PVT system as a whole cannot be achieved, which is a limitation for the overall energy efficiency evaluation and optimization of the system.
