Problems solved by technology

[0006] However, due to the large number of power grid data processing requirements, involving fault analysis, data compression, power flow calculation, vector analysis, etc.; at the same time, in order to ensure the reliable operation of the power grid, the continuous monitoring of the power grid operation status generates a huge amount of data

The use of DSP or other processors to complete grid acquisition data processing is not flexible enough, and the real-time processing capability is limited

For complex algorithms, higher-performance processors are required, and the power consumption of the system also increases. The power consumption of embedded systems is often limited, so it is difficult for traditional systems to meet the increasingly complex power grid data calculation needs.
