Solar photovoltaic power station operation and maintenance management system and method

Abstract

The invention provides a solar photovoltaic power station operation and maintenance management system and method. The operation and maintenance management system comprises a cloud storage control platform, a plurality of field solar panels and a field remote terminal unit. The on-site remote terminal unit sends collected on-site light intensity signals 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 then sends the on-site light intensity signal and the on-site wind speed information to the cloud storage control platform; the cloud storage control platform generates an operation and maintenance control signal by using the geographic information database and the real-time weather database based on the preprocessed field signal and sends the operation and maintenance control signal to a field control device; and the field control devicecontrols the state change of the field solar panel based on the operation and maintenance control signal. According to the technical scheme of the invention, the method can achieve the timely mastering of the on-site parameter change of the photovoltaic power station and the data difference provided by the real-time cloud, and selects the correct adjustment and control parameters for operation andmaintenance control.

Description

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.
