Problems solved by technology

The problem to be solved is: how to classify and process so much fault data so that it can be efficiently used in the fault monitoring system
[0005] In summary, the establishment of a highly reliable wind power monitoring system requires large-scale multi-sensor data. One of the corresponding problems is that the amount of data to be processed and stored is increased, Brings a heavy burden to both system design and technical analysis

Abstract

The invention provides method and device for processing wind power monitoring system data. The method comprises the following steps of: acquiring wind power system data to be monitored and storing the wind power system data to be monitored into a buffer register layer; storing the data to be monitored into a short-term memory layer and judging whether the data to be monitored in the short-term memory layer periodically fluctuates around a preset normal value when judging whether the offset preset normal value of the data to be monitored in the buffer register layer is greater than a preset fault threshold; if yes, storing the data to be monitored into a preset storage area, and if not, storing the data to be monitored into a long-term memory and alarm layer and carrying out the fault diagnosis and processing on the data to be monitored in the long-term memory and alarm layer; and otherwise, forgetting the data to be monitored. By processing the data to be monitored in three levels according to the memory mode angle, the processing on the data to be monitored can be selectively finished, the pressure for storage and subsequent fault processing can be greatly reduced ,which has important value for optimal design of monitoring systems of large-sized large-scale wind power systems.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a method and device for processing data of a wind power monitoring system. Background technique [0002] Wind power generation is a type of new energy technology that has received great attention in recent years. Especially in the past ten years, the scale of wind farms has expanded rapidly, showing the trend of "large capacity", "large scale" and "grid-connected". , system failures and maintenance issues are becoming increasingly prominent. Therefore, it is an important way to ensure the rapid and healthy development of the wind power industry to study the fault monitoring technology of wind power system and improve the safe operation level of the system. [0003] For the state health monitoring of wind power systems, there are mainly two types of implementation methods: one uses hardware redundancy, such as the use of multi-sensor hot backup, which increases the cost but...
