Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] Such as Figure 1-Figure 2 As shown, after a fault occurs, the combination of the switch displacement sensitive to the action of primary equipment and the peak value of current sampling is used as the driving quantity to start the automatic upload of the fault data stream, and the fault holographic system uses the same principle as the information filtering threshold to determine the information extraction. Scope and object, extract the relevant protection, fault record, and traveling wave device information for the fault channel, and then through standardization processing such as waveform standardization, sampling time scale alignment, and sampling frequency alignment, the wave recording images of the relevant channels will be formed into a comprehensive wave recording The graph analysis platform, combined with the relay protection comprehensiv...

Abstract

The invention discloses a fault hologram system based on standardization processing technology and a method thereof. The fault hologram system based on the standardization processing technology is used to widely, comprehensively, and synthetically display fault transient processes in a station from a perspective of fault increment reflection, facilitates timely and accurate fault condition understanding, scientifically analyzes fault reasons, rapidly judges occurring positions, natures and severity degrees of faults, and optimizes the power grid fault treatment process. The fault hologram system is developed by using data treatment techniques of data automation fusion and the like, is based on a multipoint region fault information synthesis analyzing thought after the faults, unifies and standardizes treatment methods through wave shapes, sampling point time scales and sampling frequency, achieves whole process dynamic display of data in different data sources on the same timer axis, uses booting logic based on combination of sampling characteristic value and switching value gallery attributes, automatically locks a fault sampling gallery, synthesizes the faults onto a fault analysis platform for normalization treatment, and improves fault treatment efficiency.

Description

technical field [0001] The invention relates to the field of power grid fault holographic systems, in particular to a fault holographic system based on standardized processing technology and a method thereof. Background technique [0002] In recent years, with the continuous expansion of the scale of the power grid and the continuous strengthening of connections, the power transmission capacity of the power grid has been effectively improved, but the probability of the spread of local faults has greatly increased. and the time required for system recovery processing. At present, three technical support systems, namely fault recorder networking, relay protection information, and traveling wave ranging, have been built and operated, and have played an active role in equipment operation management and fault analysis and processing. At present, the waveforms, sampling time scales, and sampling frequencies of different data sources in most operating fault information systems are...
