Abstract

A photovoltaic power generation electricity stealing prevention system comprises a measuring subsystem, a wireless communication subsystem, a running state judgment subsystem and a human-machine interaction subsystem. The measuring subsystem is connected with the running state judgment subsystem of the wireless communication subsystem through the wireless communication subsystem. The running state judgment subsystem is connected with the human-machine interaction subsystem and a power generating metering device. According to the photovoltaic power generation electricity stealing prevention system, a photovoltaic power generation system can be monitored in real time, cheating of the phototoxic power generating capacity is prevented, and therefore the power generating subsidy cannot be cheated.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation control, in particular to a photovoltaic power generation anti-stealing system. Background technique [0002] On November 1, 2012, the State Grid opened the acceptance of photovoltaic grid connection. According to the State Grid's "Opinions on Doing a Good Job of Distributed Photovoltaic Power Generation Grid-connected Services", the grid-connected process takes about 45 working days. When grid-connected distributed photovoltaic projects are connected to the grid for power generation, the State Grid needs to pay for the acquisition of distributed photovoltaic power at the same time. However, the difference between the price of photovoltaic power generation and the electricity price of conventional thermal power grid needs to be subsidized by the state, and this subsidy policy will be introduced soon. At present, the National Energy Administration is studying and formulating...
