[0026] The present invention provides an energy-saving control system for a photovoltaic power station, comprising a data acquisition module 101, a remote communication module 102, a processor module 103, a database 104, a judgment module 105, a circulation module 106, an early warning and alarm module 107, a solution generation module 108, a controller 109, a rectification module 110, a GSM push module 111, a client 112, a classification module 113, a compression module 114, a storage module 115, an energy efficiency optimization module 116, a maintenance module 117 and a login module 118. The above-mentioned solution solves the technical problem that the manual inspection, manual control and data analysis methods in the prior art can no longer meet the operation and maintenance requirements, thereby resulting in high operation and maintenance costs, slow fault response and low power generation efficiency.

[0027] According to this specific implementation, the data acquisition module 101 is used to monitor various parameters of the photovoltaic power station 100 in real time and transmit them to the processor module 103 through the remote communication module 102;

[0028] The processor module 103 is used to process the received data and determine whether it exceeds the threshold through the determination module 105;

[0029] When the threshold is not exceeded, the loop module 106 performs data collection and monitoring in a loop. When the threshold is exceeded, the early warning alarm module 107 issues an alarm on the client 112 through the GSM push module 111. At the same time, the solution generation module 108 generates a rectification solution and displays it on the client 112, and the rectification module 110 performs rectification.

When the threshold is not exceeded, the data collection and monitoring is performed cyclically through the circulation module 106. When the threshold is exceeded, the early warning alarm module 107 alarms on the client 112 through the GSM push module 111.

The operation and maintenance personnel can confirm the rectification or use the data as a reference for rectification. In this way, the manual inspection, manual control and data analysis methods in the prior art can no longer meet the operation and maintenance needs, thereby solving the technical problems of high operation and maintenance costs, slow fault response and low power generation efficiency.

[0031] Secondly, the classification module 113 is connected to the processor module 103, and the compression module 114 is connected to the classification module 113 and the storage module 115.

[0034] When using a photovoltaic power station energy-saving control system of this embodiment, first, the data acquisition module 101 uses high-precision, low-power Internet of Things sensor technology to monitor various parameters of the photovoltaic power station 100 in real time and transmits them to the processor module 103 through the communication technology in 4G / 5G, LoRa, and NB-IoT. The processor module 103 uses InfluxDB or TimescaleDB to process the received data, and the judgment module 105 checks the data in the database 104 to determine whether it exceeds the threshold. If it does not exceed the threshold, the loop module 106 performs data collection and monitoring in a loop. When a threshold value is exceeded, the early warning alarm module 107 issues an alarm on the client 112 via the GSM push module 111. At the same time, the solution generation module 108 obtains and generates a rectification solution from the rectification solution of the database 104 and displays it on the client 112. The rectification module 110 performs rectification. The operation and maintenance personnel can confirm the rectification or use the data as a reference for rectification. In this way, the technical problem that the manual inspection, manual control and data analysis methods in the prior art can no longer meet the operation and maintenance needs, thereby resulting in high operation and maintenance costs, slow fault response and low power generation efficiency is solved.
