Problems solved by technology

However, since the wave recording file is a larger data block compared with other data, it needs to take a certain amount of transmission time, and problems may occur if the various links of its transmission are not considered carefully

Embodiment Construction

[0020] in the attached figure 1 The three boxes in , respectively represent three different plug-ins: access plug-in, main CPU plug-in, transfer-out plug-in. In the process of processing wave recording files, information exchange is carried out between the three.

[0021] The processing method of wave recording data in the multi-plug-in embedded substation is mainly divided into three steps.

[0022] 1. Collect and organize the wave recording data to form COMTRADE format files, and manage the wave recording files and lists in the access plug-in

[0023] The collection and arrangement of wave recording data is completed by the access plug-in.

[0024] There may be many kinds of protocols for connecting plug-ins to relay protection equipment and fault recorders, but the processing of wave recording data has the following procedures:

[0025] (1) Knowing the generation of new wave recording data: When new wave recording data is generated, no matter how the substation communica...

Abstract

A method for processing recording file of multiple-plug-in component embedded type relay protection fault information system substation (embedded type station) provided by the invention is applied to the electric network relay protection fault information management system, comprises the following contents: the embedded type substation is of multiple-plug-in component structure; each plug-in component can independently operate an access or rolling-out type communication regular; each plug-in component can share data by one main CPU plug-in component; each plug-in component can be communicatedby Ethernet,; the access plug-in component can collect recording wave and tidy the data as a recording file with standard COMTRADE format, meanwhile, can manage the plug-in component recording file and list; the access plug-in component can notify the information generated by the recording file to a main CPU plug-in component; the main CPU plug-in component can acquire recording file from each access plug-in component and save the recording file to the present plug-in component, and can manage the recording file and list; the main CPU plug-in component takes charges of notifying the information generated by the recording file to the rolling-out plug-in component; the rolling-out plug-in component can acquire the recording file from the main CPU plug-in component according to the requirement of the main station, and can convey the recording file to the main station.

Description

technical field [0001] The invention is applied in the field of electric power automation of electric power systems, and particularly relates to a power grid relay protection and fault information processing system (hereinafter referred to as a fault information system). Background technique [0002] With the development of computer technology and network technology and the improvement of substation automation level, relay protection fault information systems have been established in many areas of China. The fault information system mainly focuses on the information of relay protection and fault recorder, especially the various signals, status and wave recording data when a fault occurs. However, due to the complexity of the system, data is often blocked, incomplete, or lost due to various reasons. [0003] Among all fault information, wave recording data is undoubtedly the most important content for relay protection professionals, because all state information and sampling...
