Problems solved by technology

[0003] Voltage sag is the most typical event among power quality events. Existing visualization techniques for voltage sags mainly use line depression domains to display, but such methods can only be displayed on the existing line dimension and cannot be extended to the entire space, which is not conducive to the future Line planning and site selection for sensitive loads

Abstract

The invention discloses a voltage sag sunken domain visual display method and device, and the method comprises the steps: obtaining the time data and spatial data of a disturbance event in a power system, and dividing the time data of the disturbance event into a plurality of disturbance periods through a time clustering method; obtaining the voltage sag amplitude of the disturbance event in the disturbance time period and the corresponding geographical position; assigning the voltage sag amplitude to a corresponding geographic position in a geographic information graph; and adopting differentcolors to represent the voltage sag conditions of different regions in the geographic information graph after assignment. According to the invention, the voltage sag amplitude is assigned to the corresponding geographic position in the geographic information graph, and different colors are adopted to represent the voltage sag conditions of different regions in the assigned geographic informationgraph, so that the voltage sag conditions can be clearly displayed in the whole space.

Description

technical field [0001] The present application relates to the technical field of power monitoring, and in particular to a method and device for visually displaying a voltage sag depression region. Background technique [0002] In recent years, power quality issues have been the common concern of grid companies and power users. With the gradual construction and promotion of power quality monitoring systems in various provinces, how to effectively use data analysis technology to extract information from data and establish the causal relationship of events to achieve the purpose of decision support is a development trend worthy of attention and value in power quality research. one. Visual display technology based on power quality data is the key and basis for disturbance analysis. [0003] Voltage sag is the most typical event among power quality events. Existing visualization techniques for voltage sags mainly use line depression domains to display, but such methods can only...
