Relay protection sampling data processing method and device suitable for multifunctional integration

The invention discloses a relay protection sampling data processing method and device suitable for multifunctional integration, and the method comprises the following steps: taking relay protection interruption time as a reference, and determining the frequency division multiple of sampling data; enabling each application function to select different sampling rates to perform data caching according to requirements; and enabling each application function to independently perform data processing. The method disclosed by the invention is a frequency division data sampling method based on protection interruption, can meet the independence of each function and the special requirements on sampling data, and ensures that the protection function has enough machine-hour to complete logic operationat the same time. 本发明公开了一种适用于多功能集成的继电保护采样数据处理方法及装置，包括以下过程：以继电保护中断时间为基准，确定采样数据的分频倍数；各应用功能根据需求选择不同的采样率进行数据缓存；各应用功能独立进行数据处理。本发明方法为以保护中断为基准的分频数据采样方法，能满足各功能的独立性和对采样数据的特殊需求，同时也保证保护功能有足够的机时完成逻辑运算。
