Problems solved by technology

[0004] (1) Since photovoltaic power stations are generally built in remote areas, the geographical environment and natural conditions are relatively harsh, and decentralized maintenance and manual monitoring cannot be carried out in the traditional way;
[0005] (2) The storage battery is a device with a high failure rate in photovoltaic power stations. There are many reasons for the premature failure of the storage battery. In addition to unreasonable design and inadequate maintenance and management, the unreasonable operation and management of the storage battery is an important reason for the early failure of the storage battery.

Abstract

The invention discloses a distributed photovoltaic power generation intelligent monitoring method. The method comprises the following steps that: (1) an distributed photovoltaic power generation intelligent monitoring system is prepared; (2) the data acquisition module collects data of a photovoltaic assembly and an inverter in real time, a local controller regularly acquires data collected by thedata acquisition module, and a monitoring unit integrated in a single chip microcomputer reads data from the local controller through a communication server in real time; meanwhile, the monitoring unit in the single chip microcomputer monitors the operating states of a storage battery pack in real time to obtain the operating state data; and (3) the monitoring unit stores the data in a database server, analyzes the data and remotely sends a control command to the local controller according to the analyzed data conclusion, and the local controller locally controls the inverter and / or the storage battery pack. The invention further discloses a distributed photovoltaic power generation intelligent monitoring system for implementing the above method.

Description

technical field [0001] The invention relates to a photovoltaic power generation monitoring system, in particular to a distributed photovoltaic power generation intelligent monitoring system and a monitoring method thereof. Background technique [0002] As large-scale solar power plants are built and put into operation in China, how to understand the operating status of the power plants in real time and how to meet the monitoring needs of the upper-level system or power grid dispatching system have become urgent problems to be solved. Real-time monitoring of the operating status of solar photovoltaic power plant systems, such as operating status monitoring, fault detection and early warning, environmental data collection, energy scheduling and distribution, is of great significance to improving the operating efficiency of photovoltaic systems and reducing system operating costs. [0003] At present, the following problems generally exist in solar photovoltaic power plants: ...
