Embodiment Construction

[0014] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention, and any similar structures and similar changes of the present invention should be included in the protection scope of the present invention.

[0015] figure 1 As shown, the implementation process of the power system remote signal displacement debounce method provided by the present invention is as follows:

[0016] 1) Detect the change information of the remote signaling state, if the remote signaling state changes, record the change time t of the remote signaling signal 1 , the remote signaling status value v before the change 0 , after the change, the remote signaling status value is v 1 ;

[0017] 2) Set a debounce time constant T d , if the remote signal is at t 2 time, here t 2 =t 1 +T d , the remote signaling state value is restored to v 0 , it is cons...

Abstract

The invention discloses an electric power system telesignalling displacement dithering-removing method, and relates to the technical field of data processing; a dithering-removing period is set to reduce telesignalling interference signals; a state-stable period is set to reduce repeat sending of state displacement; a telesignalling displacement event is not generated during the dithering interference-removing period, but is generated during the state-stable period; the dithering-removing period is associated with the state-stable period so as to process interference signals with different frequencies respectively; the method can rapidly process telesignalling displacement, and reduce telesignalling displacement misinformation and missing information.

Description

technical field [0001] The invention relates to data processing technology, in particular to the technology of the remote signaling frequent displacement de-jittering method of electric power system. Background technique [0002] In the power system, remote signaling is an important data type that represents the status of power equipment. Usually, the remote signaling status value is represented by Boolean quantities 0 and 1. When a fault occurs in the power system, the remote signaling status value will fluctuate frequently between 0 and 1, resulting in a large amount of jitter displacement information, which will affect the dispatcher's analysis and decision-making. In this case, it is necessary to de-jitter the data. Contents of the invention [0003] Aiming at the defects existing in the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a method for de-jittering the remote signal displacement of the electric power sys...
