Power quality monitoring method and power quality monitoring system

Abstract

The invention provides a power quality monitoring method and a power quality monitoring system. The power quality monitoring method comprises the following steps of the step a of setting up child-parent tables of a present circuit and obtaining corresponding child-parent tables of the present circuit; the step b of setting up one-to-one corresponding relations of the child-parent tables of the present circuit and caused event information of the present circuit; the step c of according to the one-to-one corresponding relations of the child-parent tables of the present circuit and the caused event information of the present circuit, searching a present circuit state of an caused event through the caused event information, and obtaining the present circuit state of the caused event; the step d of judging whether the present circuit state of the caused event is normal or not, executing different operations, and obtaining data information; the step e of analyzing the data information, and obtaining an analytical statement or a map analysis graph of an caused event source area. According to the method, the source area which caused problems of the circuit can be found, and a specific analysis report is given.

Description

technical field [0001] The invention relates to the field of power quality monitoring in electric power systems, in particular to a power quality monitoring method and a power quality monitoring system. Background technique [0002] The power quality monitoring system is a device for power quality monitoring, which needs to be used in many scenarios. [0003] Currently, the existing power quality monitoring methods and power quality monitoring devices can only monitor the occurrence of events on the monitoring line. Although the user knows that the current line has triggered an event, he does not know what the real cause of the event is, so he does not know what to do to avoid the same situation from happening again. [0004] In short, the current power quality monitoring methods cannot find the source area of ​​the circuit problem and give a specific analysis report. [0005] Therefore, a technical problem that needs to be solved urgently by those skilled in the art is: h...
