Embodiment 1
[0077] A schematic flow chart of a substation data statistics method provided by the present invention is as follows figure 1 shown, including:
[0078] Step 1: Perform a filter on the obtained substation remote signal displacement information to obtain abnormal data and normal data;
[0079] Step 2: Perform secondary filtering on the normal data to obtain abnormal operation state data and normal operation state data, as well as malfunction data and non-malfunction data;
[0080] Step 3: Make statistics on abnormal data, abnormal operation state data, malfunction data, normal operation state data and non-malfunction data respectively.
[0081] Substation data statistics methods include:
[0082] Step 101, data reading
[0083] The data of the present invention comes from the remote signal displacement historical data of the intelligent substation integrated monitoring system, and the remote signal displacement information of the substation to be analyzed is read out by usin...

[0151] A specific statistical example of substation data is given below to verify the correctness and feasibility of the method. Taking Tianjin 500kV Wuzhuang Substation as an example, read the remote signal displacement information in the historical alarm data, and the alarm time interval is 2015-11 -12~2017-12-15, the number of records in the remote signal displacement table is 825605. Table 1 is the list of data pieces after data preprocessing. Preliminarily, it can be seen that there are 122,734 (14.9%) signals that have the problem of continuously sending out two 0 or 1 displacement information. The relevant signals are worth noting; daily alarm > 10 There are 578,492 displacement signals, and 523,648 alarms > 3, accounting for 82.3% and 74.5% of the total respectively. It can be seen that frequent and jitter signals account for a relatively large proportion, so the normal operation of the remote signaling displacement signal Buried in these large numbers of frequent jitt...

[0159]Based on the same inventive concept, the present invention also provides a substation data statistics system. Since the principle of these devices to solve technical problems is similar to the substation data statistics method, the repetition will not be repeated.
[0160] The basic structure of the system is as Figure 12 As shown, including: primary filtering module, secondary filtering module and statistics module;
[0161] Among them, the primary filtering module is used to perform primary filtering on the obtained substation remote signal displacement information to obtain abnormal data and normal data;
[0162] The secondary filtering module is used to perform secondary filtering on the normal data to obtain abnormal operation status data and normal operation status data, as well as malfunction data and non-malfunction data;
[0163] The statistics module is used to make statistics on abnormal data, abnormal operation state data, malfunction data, normal operation...
