Problems solved by technology

Therefore, using traditional methods can only filter out some frequently jittering signals, and it is impossible to judge the amount of remote signals that only operate dozens or several times a day; and each remote signal needs time to wait, and the real-time performance of the signal caused a certain impact

Embodiment Construction

[0023] see figure 1 , the embodiment of the data filtering preprocessing method based on the distribution automation operation index application of the present invention comprises the following steps:

[0024] 1. First, set a jitter judgment cycle for the remote signal displacement signal and perform jitter counting; the length of the judgment cycle can be set flexibly, the minimum value of the jitter judgment cycle can be set to 1 second, and the maximum value can be set to 2 32 Seconds, the minimum value of the jitter count supports setting 1, and the maximum value supports setting 2 16 , the jitter judgment period set in this example is 86400 seconds, and the jitter count is set to 10;

[0025] 2. According to the jitter judgment period and jitter count set in step 1, in the distribution automation system, a jitter judgment queue for remote signal displacement signals is established for each remote signal, and the length of the queue is the length of the jitter count set i...

Abstract

The invention discloses a data filtering jittering pre-processing method based on power distribution automatic running index application. By the method, the change rule of a single telecommunication state is analyzed, and integral analysis from angles of full station, a fault signal and remote control operation is performed; with regard to the condition that the telecommunication states are separated and are alternative, whether a signal is a jittering signal is judged by setting a jittering judgment period and jittering count and simultaneously according to whether remote control operation and fault signal generation within a certain time are performed and whether other telecommunication in the same station room is changed; and for the condition that the same telecommunication sate is continuously transmitted, whether the signal is the jittering signal is judged according to whether deflection is generated by telecommunication or not and a fault signal is generated or not with regard to telecommunication deflection sent repeatedly within the jittering judgment period, and the risk of filtering a normal signal is reduced. By the method, the jittering signal can be relatively ideally and rapidly filtered, and meanwhile, the conditions of telecommunication misinformation and leakage information are reduced.

Description

technical field [0001] The invention relates to a data filtering and preprocessing method based on the application of distribution automation operation indicators. Background technique [0002] The remote signal displacement signal of the distribution automation system (abbreviated as remote signal) is one of the most important signals required for power grid dispatching, and it reflects the actual operating status of various electrical equipment in the station. With the continuous expansion of the scale of distribution automation system and the increase of the number of distribution terminal construction and operation, distribution automation system plays an increasingly important role in power grid production and dispatching. Therefore, the remote signal displacement signal should be very accurate and reliable, otherwise it may affect the dispatcher's analysis and decision-making, and bring extremely adverse effects on power grid dispatching. However, in actual operation,...
