Distributed photovoltaic power station information acquisition and monitoring device

Abstract

A distributed photovoltaic power station information acquisition and monitoring device relates to the technical field of photovoltaic power stations and is mainly composed of a hardware system and a software system. The hardware system is realized based on an industrial embedded core board of a 32-bit ARM9 microprocessor and consists of a core board, a power supply management unit, a clock management unit, a storage unit, a liquid crystal display unit and a peripheral interface unit group, the software system is divided into a system support layer, a service support layer and an application layer, information is acquired by a downlink data acquisition module and processed by a data statistics management module, and then information acquisition and monitoring are completed through data uploading and monitoring information transmission of a data uploading communication module. The device has a beneficial effect that a data timeliness inspection technology, a data integrity inspection technology and a data self-repairing technology which are suitable for distributed photovoltaic power station whole-station data monitoring are adopted so that timeliness, integrity and accuracy of the acquired data are ensured.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power plants, in particular to a device for collecting and monitoring distributed photovoltaic power plant information. Background technique [0002] In order to promote the energy production and consumption revolution, advocate a clean, low-carbon, safe and efficient energy system, and build an overall strategic plan for a charming China, the state has issued a series of policies to encourage and support the development of distributed energy. According to the release, my country's distributed energy started late, and most distributed energy projects are at a standstill due to problems such as power grid connection, efficiency or technology. At present, most distributed photovoltaic power plants do not have effective communication capabilities and remote monitoring and management capabilities. A small number of power stations are equipped with photovoltaic information collection devices, but t...

Problems solved by technology

At present, most distributed photovoltaic power plants do not have effective communication capabilities and remote monitoring and management capabilities. A small number of power stations are equipped with photovoltaic information collection devices, but they can only collect a small amount of information from a few devices such as inverters, which cannot meet the needs of power automation management.

Due to the large quantity, variety and complex data structure of photovoltaic monitoring data, it is difficult for traditional photovoltaic information collection devices to adapt well to the needs of this scenario
