Abstract

The invention discloses a power quality monitoring system, which includes a power data acquisition module, and the like. The power quality monitoring system has the advantages as follows: power quality problems can be detected in real time to ensure residential and industrial power consumption demands; power compensation can be provided when the power quality is monitored to be abnormal; stream computing is coupled to the system, and high-performance transformation on the traditional signal transmission is carried out; interference can be reduced while monitoring data is ensured; misoperationof relay protection is eliminated; safe operation of a power grid monitoring system is improved; and the loss caused by abnormal power quality is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric equipment monitoring. It specifically relates to a power quality monitoring system. Background technique [0002] The people's requirements for the quality of life are constantly improving, and power quality must be improved. Monitoring has become the focus of power companies in various places. Accidents caused by serious power quality problems have occurred from time to time, resulting in the loss of human, material and financial resources. Therefore, accurate and rapid monitoring of power quality And real-time security monitoring is very important. However, the power quality monitoring systems in the prior art only have the function of monitoring the power quality in the power system, and the instability of the power quality results in waste of power and low efficiency. Contents of the invention [0003] The object of the present invention is to provide a power quality monitoring system in ...
