Embodiment 1
[0049] The data splicing method provided by the present invention includes horizontal splicing of fault recording data of each channel of a single fault recording file and longitudinal splicing of all fault recording files, specifically comprising the following steps:
[0050] 1. Horizontal splicing
[0051] Such as figure 1 As shown, the horizontal splicing stage specifically includes the following steps:
[0052] S1. Obtain a fault recording file, the fault recording file includes m channels, respectively G(1), G(2), G(3), ..., G(j), ..., G (m); Record the fault recording data included in channel G(j) as A(1), A(2), A(3),..., A(i),..., A(n), The initial value of j is 1; then the start time of the above fault recording data is obtained: ST(1), ST(2), ST(3), ..., ST(i), ..., ST(n), and end time: ET(1), ET(2), ET(3), ..., ET(i), ..., ET(n), and record the above faults according to the start time of each fault recording data sort the data;
[0053] S2. According to the sort...

Abstract
The invention provides a data splicing method. The method comprises the two steps that first, fault recording data contained in each fault recording file is subjected to data splicing, and second the fault recording files are subjected to data splicing. After splicing in the two steps, all the fault recording data and fault recording files can be spliced together, and convenience is brought to subsequent system fault analysis.
Description
technical field [0001] 本发明涉及电网中故障录波数据分析领域,更具体地,涉及一种故障录波数据拼接方法。 Background technique [0002] 随着国民经济和社会的不断发展,电力负荷迅速增长,输配电的规模在不断的扩大,电力系统日益复杂。故障录波装置是记录电力系统中电气量的重要设备,其反应了电力系统中各个电力设备的运行状况,随着用户对电力供应的安全和质量要求越来越高,在分析电力系统的运行情况时,通过故障录波数据来分析是其中一种重要的手段。 [0003] 现有的故障录波装置标准对存储故障录波数据的COMTRADE文件有着格式方面的限制,目前故障录波数据的长度与装置设置的定值相关。受制于硬件的限制,现有的故障录波装置所记录的单个故障录波数据的长度约在3S以内,若电力系统发生长时间的振荡故障,那么该状况将会分割记录在多个不同的故障录波数据中。如在抽水蓄能领域,由于机组具有发电机和电动机两种运行工况,在调节负荷时,经常在不同运行工况中频繁转换。在启动过程中,频率和电压一般需要2-10min的时间从零逐步上升至额定值,因此启动阶段的故障录波数据一般分割成多个故障录波数据进行存储。 [0004] 目前,基于故障录波数据分析的软件的使用基础是针对于某一个故障录波数据,不能将多个故障录波数据融合在一起进行分析,因此不利用对持续时间较长的电力系统故障进行分析,难以有效的满足实际用户的要求。 Contents of the invention [0005] 本发明为解决现有技术的以上难题,提供了一种故障录波数据拼接方法,该方法能够将多个故障录波文件拼接在一起,方便后续的故障分析。 [0006] For realizing above-mentioned purpose of the invention, the technical scheme that adopts is: [0007] 一种故障录波数据拼接方法,其特征在于:包括对单个故障录波文件各个通道故障录波数据的横向拼接和对所有故障录波文件的纵向拼接,具体包括以下步骤: [0008] 一、横向拼接 [0009] S1.获取一个故障录波文件,所述故障录波文件包括有m个通道,分别为G(1)、G(2)、G(3)、……、G(j)、…...
