Description

technical field

[0001] The present invention relates to the technical field of power quality analysis of distribution network, and more specifically, relates to a dedicated chip architecture for high-efficiency power quality analysis at the distribution network terminal side. Background technique

[0002] The distribution network is at the end of the power system and is a bridge connecting the power system and users. It directly affects the power consumption of power users. Therefore, the reliability of the distribution network will also directly affect the power supply to the system and users. Reliability has an impact; as the sensory layer of the distribution network, the distribution terminal equipment is the source of the data required in the entire system, and it is also the device that executes the control instructions. An important function of the power distribution terminal is to communicate with the main power distribution station or the terminal, so as to realize t...
