Identification of static voltage load characteristics is not a trivial task. It is extremely difficult to develop a single methodology that will allow achieving the required accuracy results for any input data. The authors made an attempt to solve the problem, developed a method based on the use of methods for processing large data sets – BigData. One of the most important stages of this method is the stage of cluster analysis. The problem of choosing a method of cluster analysis also has nuances: it is necessary to maintain a balance between time and accuracy of calculations, while performing calculations with sufficient accuracy on various data. A number of domestic and foreign authors have investigated this issue, but the proposed options cannot be used in the developed methodology. The purpose of this research is to develop a cluster analysis method that will satisfy the above requirements. The author’s method is based on the k-means method. The main feature of the author’s method is the mechanism of initial generation of cluster centroids, which allows to exclude the influence of random generation of two-dimensional coordinates imperfection and to achieve uniform generation of initial clusters centers. The developed method was tested on a model problem with all known solutions, which can be easily verified analytically. Also the method was tested on actual industrial load data. The results obtained the requirements of accuracy and calculation speed and allow us to conclude that the developed method of cluster analysis can be used in the task of identifying static voltage load characteristics.

Попов М.Г. Основания привлечения контролирующих должника лиц к ответственности В настоящей статье рассматриваются условия и основания для привлечения к ответственности контролирующих лиц в соответствии с иностранным и российским законодательством как в рамках дела о банкротстве, так за его рамками. В частности, анализируются условия привлечения к ответственности контролирующих лиц в праве Г ермании, Франции и Бельгии. На основе сравнительно-правового анализа делаются выводы о возможных путях дальнейшего совершенствования российского законодательства об ответственности контролирующих лиц. Ключевые слова: ответственность контролирующих лиц, снятие корпоративных покровов, субсидиарная ответственность в банкротстве, недостаточная капитализация, злоупотребление принципом ограниченной ответственности.

Grounds for Bringing of Persons Controlling a Debtor to Liability The present article contains analysis of criteria and legal grounds of responsibility and imputability of natural and legal persons exercising control over the debtor according to foreign and Russian regulatory framework both outside and within the scope of insolvency proceedings. In particular, the criteria for responsibility of such persons in Germany, France and Belgium are considered. Based on the comparative analysis some conclusions are reached as to the options of further enhancement of Russian regulatory framework on the matter.

The non-stationary mode characteristics of the generalized power equipment numerical experiments are analyzed, and the electrophysical dynamic characteristics and reliability of the IGBT in the power conversion process are studied. Based on the results of short-circuit numerical experiments and the steady-state mode of pulse width control, this paper introduces a method for analyzing the nonlinear dynamic process of IGBT drive modules during power conversion. The structure of a software algorithm for conducting numerical experiments to study the non-stationary operation mode of asynchronous electromechanical machines is proposed, and the numerical solution of transient nonlinear differential-algebraic equations of electrical equipment is described by gradient parameter method. The results of this study will help to study the dynamic nonlinear characteristics of the operation process of power and electrical equipment control and automation tools, and have practical significance for evaluating the computational efficiency and reliability of developing mathematical models in the next research work.
