Embodiment Construction

[0040] The present invention will be described in further detail in conjunction with the accompanying drawings and specific embodiments.

[0041] Firstly, the power stealing scenario of the distributed photovoltaic power generation system is analyzed.

[0042] At present, the common distributed photovoltaic power generation stealing methods include mains rectification and inverter method, mains reconnection method, photovoltaic meter boosting method, and photovoltaic meter boosting method. The above four ways of stealing electricity can make the distributed photovoltaic billing electric energy meter over-count the power generation, and the owners of distributed photovoltaic power generation can use this to defraud the state subsidy.

[0043] The principle of normal access to 220V distributed photovoltaic power generation metering is as follows: figure 1 shown. A photovoltaic power generation meter is installed at the grid-connected point of the photovoltaic power generation ...

Abstract

The invention discloses a method for identifying electricity stealing methods of distributed photovoltaic power generation. The electricity stealing scene analysis is carried out by the table rising current method, and then the corresponding electricity stealing identification scheme is given based on its electricity stealing characteristics. Through the preliminary identification of distributed photovoltaic power generation electricity stealing methods, it can provide reference for inspectors and improve the pertinence of investigation.

Description

technical field [0001] The invention relates to a method for identifying electricity stealing methods of distributed photovoltaic power generation, and belongs to the technical field of photovoltaic power generation management and control. Background technique [0002] As an important application method of solar power generation, distributed photovoltaic power generation can make full use of the characteristics of the widespread existence of solar energy and avoid the site constraints of centralized construction. Especially in the face of the reality of densely populated middle and eastern my country, its large-scale application prospects are extremely broad. Governments at all levels in my country attach great importance to the development of the distributed photovoltaic industry, and the installed capacity of distributed photovoltaics has grown rapidly. [0003] Unlike traditional power users who generally only install gateway meters and bill one-way, distributed photovolt...
