A distributed new energy grid-connected data analysis and diagnosis system

Abstract

The invention provides a distributed new energy grid-connected data analysis and diagnosis system which comprises a data acquisition module, a diagnosis module, a verification module, a statistics module and a report transmission module. According to the invention, distributed new energy data are comprehensively analyzed by the diagnosis module and the verification module; the statistics module generates an analysis and diagnosis report according to the data analysis result; existing problems are listed in an easy-to-understand manner, which is convenient for operation and maintenance personnel to analyze and clearly know the existing problems, quickly acquire the cause of a failure and potential risks, and better deal with the problems; and the normal operation of a power station is ensured.

Description

technical field [0001] The invention relates to the technical field of power system data processing, in particular to a distributed new energy grid-connected data analysis and diagnosis system. Background technique [0002] As the country vigorously develops clean energy, distributed new energy power stations are built all over the country, and distributed new energy data are transmitted and connected to the power system through wireless channels. Due to the wireless transmission, in order to comply with the power safety regulations, the distributed new energy data is first connected to the safe access area of ​​the power system and then forwarded to the power dispatching system. Distributed new energy power plants have the characteristics of decentralization, small power generation, and difficult maintenance. Especially in some remote areas, new energy power plants have abnormalities, and maintenance is extremely troublesome and the maintenance cost is also very high. It i...

Problems solved by technology

[0003] Distributed new energy data is connected to the power system. The existing power system generally only makes some simple judgments on channel interruption and whether there is data. The power system judges the result is single and cannot provide detailed analysis and diagnosis results. At the same time, for abnormal distributed new energy power plants, it is necessary to call the corresponding operation and maintenance personnel to check, and to connect a large number of distributed power plants, the operation and maintenance work is heavy

[0004] The existing distributed new energy grid-connected data collection system consists of a collection device, a vertical encryption device, and a wireless routing device (the SIM provided by the operator is inserted into the device) on the sub-station side, and a vertical encryption device, a wireless routing device ( The equipment is inserted into the wireless channel provided by the operator) to form a wireless channel. There are many factors that affect data collection. The existing power diagnosis method can no longer meet the demand.
