Photovoltaic power plant operation real-time information management system and management method

Abstract

A photovoltaic power plant operation real-time information management system comprises a data acquisition module, a big data platform and a real-time information processing module. The data acquisition module is used for being connected with photovoltaic power plant operation equipment, acquiring real-time data in the operation process of the equipment in real time and sending the real-time data to the big data platform; the big data platform is used for receiving and storing the real-time data, sent by the data acquisition module, of the photovoltaic power plant operation equipment; and the real-time information processing module is used for carrying out state monitoring, on-line analysis, intelligent alarm, trend analysis and off-line statistical analysis on operation equipment of the photovoltaic power plant based on the real-time data received and stored by the big data platform. According to the technical scheme provided by the invention, the functions of real-time data acquisition, equipment fault topology analysis, intelligent fault tracing and intelligent fault processing alarm of various photovoltaic power plant equipment and GB-level real-time data streams generated undermulti-level hardware topology are realized.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a real-time information management system and a management method for the operation of a photovoltaic power plant. Background technique [0002] Compared with the continuous reduction of traditional energy consumption and the environmental problems it brings, photovoltaic has become an important source of power generation due to its advantages of no risk of depletion, low pollution, and low cost. It has been vigorously developed by various countries in recent years. [0003] Photovoltaic power plants involve photovoltaic panels, brackets, combiner boxes, inverter emerging equipment, and traditional power equipment such as lines, transformers, and substations, which makes a large number of operating equipment in a medium-sized or above photovoltaic power plant, and the generated operating data is also massive. . If it is to achieve high-temporal-spatial resolution ful...

Problems solved by technology

However, the traditional power station real-time information management system mainly uses a real-time database based on a single PC to realize simple online data processing and event alarm services, and cannot provide the above-mentioned real-time data quality control and online aggregation analysis capabilities for GB-level data streams

The traditional power station real-time information management system mainly uses the traditional relational database to realize the storage of sampling historical data, which cannot provide the above-mentioned efficient storage of TB-level data and second-level response ability to complex query retrieval

There are many types of photovoltaic power plant equipment, and the hardware topology is deep, which brings great difficulties to online troubleshooting and fault inspection.

There is an urgent demand for intelligent alarm functions that can realize equipment fault topology analysis, fault intelligent traceability, and fault handling suggestions, which cannot be provided by traditional power plant information management systems
