Problems solved by technology
The closed-loop tracking system can track the sun more accurately, while the open-loop tracking system often causes errors to accumulate during the tracking process; Or the control strategy is effective. If the data collected by the relevant parameter sensors on site is not accurate enough, the obtained control strategy will not be able to achieve effective tracking control, but will reduce the power generation efficiency.

The invention proposes a solar photovoltaic power station operation and maintenance management system and method. The operation and maintenance management system includes a cloud storage control platform, multiple on-site solar panels and on-site remote terminal units. The on-site remote terminal unit sends the collected on-site light intensity signal and on-site wind speed information to the on-site edge computing terminal; the on-site edge computing terminal preprocesses the on-site light intensity signal and the on-site wind speed information and sends them to the on-site The cloud storage control platform; the cloud storage control platform uses the geographic information database and the real-time weather database to generate an operation and maintenance control signal based on the preprocessed field signal and sends it to the field control device; the field control device is based on the The operation and maintenance control signal controls the state change of the on-site solar panels. The technical solution of the present invention can timely grasp the difference between the parameter changes on the site of the photovoltaic power station and the data provided by the real-time cloud, so as to select the correct adjustment parameters for operation and maintenance control.
Description
