A photovoltaic power station information analysis cloud platform and a system

Abstract

The invention discloses a photovoltaic power station information analysis cloud platform and a system. The cloud platform comprises a communication management module, which is used for receiving datasent by at least one collector and storing the data into a first database according to predetermined rules. Wherein the data comprises real-time data of connected photovoltaic power stations collectedby each collector; A database middleware module, configured to acquire the real-time data from the first database and store the real-time data in a history data table of the second database as history data; The cloud service master module is configured to perform analysis according to the real-time data obtained from the first database and the historical data obtained from the second database torealize statistical analysis of each photovoltaic power station. The invention is based on the cloud deployment design, so that a small number of operation and maintenance personnel can monitor more photovoltaic power stations, and the data of the upper cloud can be compared and analyzed, and the operation and maintenance of the power station can be optimized by data accumulation.

Description

technical field [0001] The invention relates to the photovoltaic field, in particular to a photovoltaic power plant information analysis cloud platform and system. Background technique [0002] Most of the existing photovoltaic power station monitoring is based on the local centralized monitoring of the power station, usually using several separate measurement and control devices, using the RS-485 interface to read data from the hardware with the Modbus protocol. Each measurement and control station, as a substation, converts the data into the format of the IEC-104 protocol, and uses itself as a substation to access the switch to accept the data request from the local monitoring master station. After the data enters the master station, it is analyzed and displayed on the SCADA interface of the relay protection manufacturer. [0003] The inventor finds in the process of implementing the present invention that there are at least the following defects in the prior art: [000...

AI Technical Summary

Problems solved by technology

[0004] 1. Someone needs to be on duty: because the data can only be monitored locally, operation and maintenance personnel are required to be on duty at the monitoring point to ensure timely detection of problems, and the cost of manpower and maintaining the working environment of personnel is high

The data cannot be uploaded and integrated in time, and it is impossible to effectively compare and analyze the operation of the power station through data integration

[0005] 2. The cost of equipment procurement and access is high: for local monitoring, it is necessary to purchase the measurement and control and switches of each device, and in order to ensure the reliability of the connection between measurement and control and local monitoring, it is necessary to find a manufacturer for on-site joint debugging
