Data and feature determine the upper limit of machine learning, and model and algorithm only approach this upper limit, therefore
Feature Engineering is extremely important.The data that PMU is acquired in electric system are higher-dimension timing, and as electric system scale increases,
Data volume is also bigger, algorithm arithmetic speed is required higher, it is therefore necessary to initial data construction feature amount.Construction feature
Amount need to follow following principle:
1) characteristic quantity can be well reflected the generation of current break；
2) characteristic quantity is unrelated with electric system scale；
3) calculating of characteristic quantity should can guarantee temporal rapidity.
First according to the variation of operating status in electric system before and after current break, and selected with reference to other researchers in feature
It is as shown in table 1 to have chosen 6 features for the experience selected.
According to features described above, first with the correlation between Pearson correlation coefficient analysis feature, come judging characteristic it
Between whether there is information redundancy, related coefficient size indicates the linearly related degree between two variables fi and fj, calculates public
Formula is shown below:
In formula: the value range of c is -1≤c≤1.If usually | c | > 0.5, it is believed that the two has linear dependence；C=0
It represents completely not linearly related；C > 0, which is represented, to be positively correlated.
The result finally calculated according to aforesaid way retains and deletes corresponding feature progress aspect of model input data and builds
Mould.
Current break reason method of discrimination based on XGBoost algorithm, includes the following steps:
Step (1), using D5000, PMS, OMS, on-Line Monitor Device under the various methods of operation, the electricity that is respectively spaced
The data such as stream, load, temperature；The a large amount of and related initial data of current break is consequently formed.
Step (2) extracts feature from initial data, and determines mutation label；Utilize D5000 system power load data
Determine whether that current break occurs；For all kinds of methods of operation, all kinds of electrical measure features are extracted, are calculated as subsequent XGBoost
The feature of method inputs；It is consequently formed a certain number of for modeling the sample data of current break.
Step (3) using XGBoost algorithm and carries out applicability improvement, carries out model instruction using the sample data of acquisition
Practice；In the training process, the feature different for Type Ⅰ Ⅱ error severity during current break prediction, introduces attention system
The loss function of several pairs of XGBoost algorithms is modified, so that model reduces the prediction case of unstable sample；It uses
Logistic function is used for model output probability, and for measuring the degree of reliability of XGBoost model output, prevention part is accidentally
Prediction.
Step (4) after XGBoost model training is mature, is believed according to the power grid real time execution that D5000 system is recorded
Breath is configured to the electrical measure feature of reflection power network current mutation；XGBoost model is inputted, it can real time discriminating electric system
Current break brought by certain possible failures.
Wherein, feature refers to station equipment combined electric amount, and need to extract is history mutation time of origin every interior master
Change, route, switch electric current value tag, the numerical value set combined by these features is called mutation label.
Be able to reflect power network current mutation electrical measure feature include history mutation occur when interval in main transformer, line
Road, switch electric current value tag, include each high, normal, basic main transformer current value, line electricity flow valuve, switching current value, when history is normal
When interval in main transformer, route, switch electric current value tag, include each high, normal, basic main transformer current value, line electricity flow valuve, switching current
Value.
The position of current break is determined, when current break occurs, specifically with equipment in a substation interval
Current value variation stability bandwidth come determine whether occur current break, such as: the 1# main transformer current value amplitude and history of Ke Yanbian
The same period is not inconsistent, or deviates practical experience amplitude, then knows mutation hair on the 1# main transformer of Ke Yanbian.
The above-mentioned current break reason method of discrimination based on XGBoost algorithm, has the advantages that
(1) since XGBoost can use multithreads computing automatically, arithmetic speed is fast, is suitble to the extensive electricity of processing
Force data.
(2) in model on increase the regularization term constituted with the complexity of tree so that its generalization ability gets a promotion, have
Effect solves over-fitting；
(3) it since XGBoost is Tree-structure Model, does not need to various data normalizations collected in electric system,
And missing values caused by capable of being effectively treated for some reason, it is suitable for the current break of spacing current.
