Method for monitoring photovoltaic power station by mobile phone

Abstract

The invention provides a method for monitoring a photovoltaic power station by a mobile phone. The method comprises: an inverter collects state information of a photovoltaic array, wherein an electromagnetic radiation sensor is arranged on the inverter; an information collection uploading device is used for collecting photovoltaic array state information and inverter state information; the information collected by the information collection uploading device is transmitted to a server by an SIM card or a USIM card; and after an intelligent terminal receives the stored data by means of wireless transmission, the photovoltaic array state information and inverter state information are displayed. Therefore, the states of the inverter and the photovoltaic array can be monitored simultaneously; and the RS485 length can be reduced under the circumstance that the data transmission smoothness is kept, so that the cost is lowered.

Description

technical field [0001] The invention relates to a method for monitoring a photovoltaic power station, in particular to a method for monitoring a photovoltaic power station through a mobile phone. Background technique [0002] Since the beginning of the 21st century, the development of renewable energy has become a trend. More and more countries and regions have realized that only the development of renewable energy is the way out to solve energy and environmental problems. As a steady stream of renewable energy, Solar energy has long been valued by people, but it has not been applied on a large scale due to cost and scale issues. Since the beginning of the 21st century, with the advancement of industry and technology, the cost of solar energy has dropped on a large scale, and it is currently in the embryonic stage of large-scale application. The green, pollution-free and easy-to-maintain characteristics of solar energy make solar energy the most promising renewable energy i...

[0002] Since the beginning of the 21st century, the development of renewable energy has become a trend. More and more countries and regions have realized that only the development of renewable energy is the way out to solve energy and environmental problems. As a steady stream of renewable energy, Solar energy has been valued by people for a long time, but has not been applied on a large scale due to cost and scale issues

Different from the real-time monitoring of the power grid, it is difficult for many distributed solar power plants and independent power plants to achieve 24-hour real-time monitoring

The current solar energy can only simply monitor the power station data, and does not have real-time remote alarm and remote real-time reminder functions, which is very unfavorable for the promotion and maintenance of solar power stations

[0004] In addition, in the prior art, an RS485 bus is used to connect the inverter and the information collection uploader, and wireless transmission is used between the information collection uploader and the server. Due to the limitation of the transmission distance of the wireless signal, the information collection uploader must be close to the server and far away from it. inverter, so the length of the RS485 bus is increased, and the status monitoring of the inverter is usually not carried out in the prior art, and the photovoltaic inverter is an important part of the photovoltaic power generation system, and its performance and operating status will directly Affect the efficiency of the entire photovoltaic power generation system, and a photovoltaic inverter in an abnormal working state will endanger the safe operation of the connected grid

Therefore, it is necessary to conduct an online evaluation of the working status of the photovoltaic inverter to detect the problems of the photovoltaic inverter in advance and avoid the impact on the safety of the power grid due to the failure of the photovoltaic inverter
