Household photovoltaic power generation and power consumption intelligent monitoring system

Abstract

The invention provides a household photovoltaic power generation and power consumption intelligent monitoring system, which is used for solving the problems that a photovoltaic power generation monitoring system can only monitor the state of a photovoltaic inverter but cannot accurately monitor power generation data and power consumption data at the same time in the prior art. The system comprisesa metering module, a protection module and a functional processing module, wherein the metering module is used for metering power generation data information and power consumption data information inphotovoltaic power generation and power consumption processes; the protection module is used for monitoring and protecting surges and overvoltage and undervoltage states in the photovoltaic power generation and power consumption processes; the functional processing module is used for processing, analyzing and storing the power consumption data information and the power generation data informationmetered by the metering module, and collected inverter data information collected by the metering module in the photovoltaic power generation and power consumption processes. The comprehensive analysis of the photovoltaic power generation data and the power consumption data, the reading and analyzing on the inverter data and the state monitoring on the photovoltaic power generation data and powerconsumption processes can be realized by adopting the system provided by the invention.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation monitoring, in particular to a household photovoltaic power generation and electricity consumption intelligent monitoring system. Background technique [0002] With the rapid development of photovoltaic grid-connected power generation technology, driven by the government's supportive policies, in recent years, with the continuous improvement of my country's photovoltaic power generation policy, areas with inconvenient transportation such as mountainous areas, pastoral areas, border defense, and islands can use photovoltaic power generation. system to generate electricity, in the solar photovoltaic system currently used, all solar panels are usually connected to a converter box first, and then connected to the grid through it, so when one or some panels fail, it is difficult Monitoring, and the power generated by the user can only be calculated based on the whole, and the power generated ...
