Abstract

The invention discloses a data processing mechanism of a photovoltaic power station data collector in an off-grid state, and relates to the technical field of electric power data collection. The method mainly comprises the following steps: initializing a system; collecting inverter data, and keeping communication with the platform; and performing storage and transmission of data. Data informationis stored when a network is disconnected, and time information is added to each frame of data. A data uploading time period is set when historical data is uploaded, and the historical data is uploadedwhen a state grid platform server is idle, so that the platform burden is reduced. Data uploading times are set, sending is stopped if sending is successful, multiple times of sending is attempted ifsending fails, mistaken sending, missing sending and frequent sending of historical data are prevented, the problems that historical data of a data collector are uploaded uninterruptedly and uploadeddisorderly due to network interruption are solved, power station data are more perfect, and fault traceability is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power data collection, and in particular relates to a data processing mechanism for a data collector of a photovoltaic power station in an off-grid state. Background technique [0002] The data collector is a special hardware device used for national power station information monitoring and monitoring. After the data collector is connected, it can conduct panoramic monitoring of photovoltaic projects in the region from the dimensions of power station installation, power generation, operation and maintenance, etc., remotely and real-time control the health distribution status of the power station, power generation efficiency, etc., and realize real-time tracking and management of the power station. [0003] When the collector is running normally, the network interruption causes the data loss of the power station: 1. The cloud platform server of the photovoltaic monitoring center is unstable, resul...
