Abstract

The invention discloses a visualization method for real-time condition monitoring of synchronous phasor of power distribution network, which comprises: acquiring synchronous phasor measurement information of power distribution network in real time, and drawing a micro trend graph according to the measurement information; extracting synchronous phasor cross-section data at the current moment and obtaining non-electric quantity information corresponding to the cross-section data in real time; performing spatial interpolation processing on the frequency data in the synchronous phasor cross-section data to draw a frequency contour line layer; drawing a valid voltage value circular primitive based on the valid voltage data in the synchronous phasor cross-section data, drawing a rotating phasorprimitive based on the voltage phase angle data in the synchronous phasor cross-section data, drawing a synchronous voltage phasor layer based on the rotating phasor primitive and the valid voltage value circular primitive; drawing a non-electric quantity information layer based on real-time acquired non-electric quantity information; superimposing the frequency contour line layer, a synchronous voltage phasor layer, a non-electric quantity information layer, and a micro trend graph in a geographic information system; the display and multi-screen display of the micro trend graph are achieved by human-computer interaction response.

Description

technical field [0001] The invention relates to the technical field of power system state monitoring, in particular to a visualization method suitable for real-time state monitoring of distribution network synchronous phasors. Background technique [0002] Condition monitoring is the guarantee for the intelligent, safe and efficient operation of complex power grids. It relies on secondary measurement equipment distributed in the power system to collect monitoring information, obtain the real-time power flow of the current system, and can truly and effectively identify the real-time status of the system. On the side of the distribution network, a large number of distributed renewable resources are infiltrated and connected, coupled with the development of technologies such as energy storage, electric vehicles, and small gas turbines, so that a variety of energy sources are gathered on the side of the distribution network. The traditional "source-network-load" structure The on...
