Abstract

The invention discloses a data-analysis-based photovoltaic power generation monitoring system and method. With a wireless transmission technology, sampling is carried out on illumination intensity and temperature data in areas with same meteorological and geographical environments, the sampling data are transmitted to a data analysis system, and the data analysis system predicts a daily electric quantity limit value of each photovoltaic grid-connected point according to the sampling data and photovoltaic cell panel parameters; the daily electric quantity limit value obtained by the analysis and calculation is compared with sampling data of an electricity usage information acquisition system; and when the generating capacity becomes abnormal, a master station computer carries out early warning to warn the marketing inspections staff to carry out electricity stealing event supervision. Therefore, the generating capacities of photovoltaic power stations in a same area can be predicted accurately and the generating capacity abnormality determination accuracy is high; an abnormal situation can be warned early; and thus the marketing staff can identify a suspected electricity stealing user conveniently. And thus the daily working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation monitoring system based on data analysis, and in particular relates to a photovoltaic power generation monitoring system and method based on data analysis. Background technique [0002] As an important part of new energy, distributed photovoltaic power generation has the characteristics of flexible power generation, environmental protection, economy and compatibility with the environment. It is of great significance to optimize the energy structure, promote energy conservation and emission reduction, and achieve sustainable economic development. In August 2013, the National Development and Reform Commission issued the "Notice on Using Price Leverage to Promote the Healthy Development of the Photovoltaic Industry", which implements the policy of full power subsidy for distributed photovoltaic power generation. In this way, there will inevitably be users and units lacking in in...
