Problems solved by technology

Some large and medium-sized non-linear load user lines have begun to adopt online power quality monitoring technology to implement all-weather real-time monitoring; and through theoretical calculations such as complex Fourier transform, instantaneous reactive power theory, and harmonic subgroup algorithm, the real-time calculation of the power grid The data of various power quality indicators can be monitored in real time, but the amount of power quality data is huge. The sampling frequency of each cycle of the monitoring equipment is greater than 512 times, and the amount of data per day is as high as 17M. Conventional equipment needs to save data for more than 6 months. At least 1.26G of flash is required, so the hardware requirements are very high and the cost is very high
