Abstract

The invention discloses a distributed photovoltaic monitoring system with power generation forecasting and a monitoring method. The distributed photovoltaic monitoring system comprises a work station, a data server, a collection server, an industrial personal computer, an interchanger and a man-machine operation interface, wherein the work station, the data server and the collection server are connected into a local area network of the system; the industrial personal computer is used for collecting the information of a distributed photovoltaic power station and uploading the information to the collection server; the collection server is used for uploading the information to the local area network; the work station is used for carrying out data analysis on the information; and the man-machine operation interface is used for displaying and giving an alarm. According to the distributed photovoltaic monitoring system, distributed photovoltaic operating data can be monitored in real time, the voltage and frequency of a distributed photovoltaic power generation system are stabilized on the basis of guaranteeing the quality of electric energy, optimal operation is realized, and the distributed photovoltaic utilization rate is improved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a distributed photovoltaic monitoring system with power generation prediction. Background technique [0002] With the large-scale application of distributed power, the proportion of random, fluctuating and intermittent distributed energy in my country's power grid in the future, especially distributed photovoltaics, will become larger and larger, and will even become an indispensable part of the power grid. . A large number of distributed power generation is connected to the distribution network, and the large amount is scattered, and it is difficult for the power grid to monitor it, which will have many impacts on the safe, reliable, stable operation and control of the distribution network. [0003] At present, many scholars have conducted research on the distributed photovoltaic monitoring system. The existing photovoltaic monitoring system can realize real-time data collection and r...
