Problems solved by technology

The traditional power quality problems are mainly voltage deviation and frequency deviation, and its power quality detection device can no longer meet the requirements. Therefore, a more intelligent power quality detection device with good real-time performance, high detection accuracy and more is needed

[0003] The traditional 8-bit and 16-bit single-chip power detection equipment has disadvantages such as slow processing speed, poor real-time performance, and imperfect functions, while the power detection equipment based on DSP processors can improve the acquisition accuracy and processing speed, but the cost is relatively high , The disadvantage of high power consumption. In addition, most of the existing power quality detection systems use wired transmission. The underlying communication mostly uses field buses such as RS-485, CAN, etc., and the remote communication uses optical fiber and power carrier. Inconvenience and equipment maintenance, high engineering costs
