Regional distributed photovoltaic power theft supervision system

Abstract

The invention discloses a regional distributed photovoltaic electricity-stealing supervision system comprising a data acquisition layer, a transmission link layer, an auxiliary information layer, and a high-level application layer from bottom to top successively. The data acquisition layer collects operation of a grid connection point by means of combination of a distributed photovoltaic grid-connected interface device and an electrical information acquisition terminal. The transmission link layer carries out intelligent communication and data transmission by means of combination of a private fiber network and a GPRS / CDMA wireless transmission. The auxiliary information layer is sued for carrying out real-time massive data processing. The high-level application layer is responsible for analyzing and displaying regional distributed photovoltaic electricity-stealing supervision. According to the system disclosed by the invention, with a distributed photovoltaic output calculation model based on multi-time-scale evaluation, electricity stealing suspicion identification is carried out by using a theoretic generating capacity as a reference. With the system, the main generating capacity of the distributed photovoltaic power generation industry can be supervised effectively; the distributed photovoltaic power generation subsidy policy can be implemented well; and a technical support can be provided for promotion of healthy distributed photovoltaic development.

Description

technical field [0001] The invention relates to a regional distributed photovoltaic stealing supervision system, which belongs to the technical field of distributed photovoltaic power generation. Background technique [0002] The development of distributed photovoltaics has the characteristics of small size and high utilization rate. The development of distributed photovoltaics is carried out in densely populated areas to improve the utilization rate of new energy. With the successive promulgation of policies such as "Several Opinions on Promoting the Healthy Development of the Photovoltaic Industry" and "Opinions on Supporting Distributed Photovoltaic Power Generation Financial Services", as well as the decline in installed costs and the increase in conversion rates, distributed photovoltaics will usher in a new era. The construction boom has blossomed everywhere in households, industrial factory roofs and other fields in the actual application process. Distributed photovol...

Problems solved by technology

[0005] First, the characteristics of stealing electricity itself have brought great difficulties to the power grid company. Electric energy has the characteristics of simultaneous generation, supply, and consumption without a trace. Transfer, especially the use of high-tech electricity theft is more difficult to obtain evidence. It is impossible to investigate and deal with electricity theft cases like other theft cases.

[0006] Second, the anti-stealing force is weak. At present, the power grid company does not have a professional anti-stealing team. The anti-stealing work mainly relies on the front-line personnel of power marketing. On the one hand, the front-line marketing personnel are responsible for normal metering business and meter reading charges , Troubleshooting, etc., but also responsible for anti-stealing inspection work
