Abstract
The invention relates to a method for transmitting a fault recording signal of a power system. An alternating current (AC) signal passes through an analog-to-digital (A/D) conversion module, a direct current (DC) signal passes through a frequency judgment circuit module, and the AC signal and the DC signal are input into a digital signal processor (DSP) to be subjected to data processing and then input into a communication module; and the processed data are transmitted to a fault recording system server. The method can realize a remote management mode and save cost for various large power stations and transformer substations; meanwhile, the large power stations and the transformer substations are more convenient to maintain and manage.
Description
Technical field:
The present invention relates to a kind of electric power system fault record ripple method for transmitting signals, specially refer to the failure wave-recording signal transmission of many record wave system systems of power plant and transformer station.Belong to industrial circle.
Background technology:
At present, the failure wave-recording transmission principle that is applicable to each high-power station and transformer station is the AC signal on the instrument transformer to be sent to import DSP into behind the A/D modular converter and handle, the switching signal of direct current is directly imported into DSP and handled by declaring the frequency circuit module, and two kinds of signals are handled to import into more later in the computer through DSP and by daemon software and database it are analyzed and stores.Like this, must need a computer to carry out operation, so the cost height, maintenance and management is inconvenience also.
Summary of the invention:
At the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of electric power system fault record ripple method for transmitting signals, is used for the workout cost height, maintenance and management inconvenience.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is that a kind of electric power system fault record ripple method for transmitting signals is characterized in that, as follows transmission:
When (1) beginning to record ripple, switching signal flows among the DSP by declaring frequency circuit module, waveform signal by A/D modular converter process buffer circuit, and DSP carries out signal processing;
(2) with the data after the DSP processing,, be transferred in the communication module by HPI interface and buffer circuit;
(3) by netting twine the data in the communication module are sent into local area network (LAN) or INTERNET wide area network at last, finally be transferred to the fault recording system server.
The present invention can realize the long-range management mode when guaranteeing original signal transmission, can be each high-power station and transformer station and save cost, and maintenance and management is more convenient simultaneously.
Embodiment:
During work, system acquisition is to signal, and AC signal, flows among the DSP and carries out data processing by declaring the frequency circuit module by A/D modular converter, direct current signal; Data after DSP handles by HPI interface and buffer circuit, are transferred in the communication module; Data after handling the most at last by local area network (LAN) or INTERNET wide area network, are transferred to the fault recording system server.
Above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, interpolation or replacement all should belong to protection scope of the present invention.
Claims (1)
1. an electric power system fault record ripple method for transmitting signals is characterized in that, transmits as follows:
When (1) beginning to record ripple, switching signal flows among the DSP by declaring frequency circuit module, waveform signal by A/D modular converter process buffer circuit, and DSP carries out signal processing;
(2) with the data after the DSP processing,, be transferred in the communication module by HPI interface and buffer circuit;
(3) by netting twine the data in the communication module are sent into local area network (LAN) or INTERNET wide area network at last, finally be transferred to the fault recording system server.
