The performed research is devoted to the development and testing of synchronization process for the electric motors of rough group stands of the hot strip mill (HSM) 1700 PJSC “ILYICH IRON AND STEEL WORKS OF MARIUPOL”. The load on the electric motors directly depends on the distribution of pre-rolled strip reductions, which was developed in the research as favourable schedule and is in accordance with analytical calculations and experimental studies in the HSM 1700 shop environment. Reducing peak loads on electric motors due to the redistribution of reductions and synchronization of their work allowed increasing the mass of hot rolled coils at the intermediate stage of reconstruction of HSM 1700 from 9 tons to 15.83 tons. It was determined by calculation that the maximum length of a slab with a basic thickness of 150 mm, which allows implementing the synchronization processes on the HSM 1700, is 9320 mm. It is shown that a further increasing in the slab length requires of additional synchronization of electric motors of HSM 1700 rough stands No. 2-4. The required power of the electric motors of the stands was determined after synchronization, taking into account the load while the pre-rolled strip was in two adjacent stands at the same time. It was found that the required electric motor power does not exceed the design value of 8000 kW.
本课题主要研究的是1700热连轧机(HSM)粗组机架电机同步过程的开发和测试。电动机的负荷直接取决于预轧带材减径的分布,这是在研究中制定的有利计划,并与HSM 1700车间环境的分析计算和实验研究相一致。由于减速器的重新分配和电动机工作的同步,减少了电动机的峰值负荷,从而使热轧卷板的质量在HSM 1700重建的中间阶段从9吨增加到15.83吨。通过计算确定,在1700型高速铣床上实现同步加工时,基本厚度为150 mm的板坯的最大长度为9320 mm。结果表明,进一步增加板坯长度需要hsm1700 2 ~ 4号毛坯机架的电动机额外同步。考虑预轧带材同时在相邻两个机架时的负荷,同步确定机架电机所需功率。经研究发现,所需电机功率不超过设计值8000kw。

The paper discusses the problems associated with adequate modeling of dynamic processes in an energy gas turbine unit with active magnetic bearings (AMBs) as rotor supports. This unit is a part of the gas turbine cogeneration plant (GT CP). The subject of the research is dynamics of turbine and generator rotors. The problem of modeling the phenomena of rotor dynamics at operating modes is solved with full consideration of controlled electromagnetic processes in circuits of active magnetic bearings. Their analysis is performed using the contour flux method utilizing detailed AMB equivalent circuit substitution schemes. They take into account almost all significant elements of the magnetic circuit (air gaps, sections of magnetic cores, grooves with windings, coils and other parts). Mathematical description of rotor dynamics of this mechatronic system is performed using the Lagrange-Maxwell equations. Simulation computational studies are based on integrating the resulting nonlinear system of differential equations for generalized coordinates and flux linkages of electric circuits of AMB coils. It is performed using the high-order Runge-Kutta numerical procedure. The simulation results include Campbell diagrams and amplitude-frequency characteristics of rotating rotors. Validation of the proposed approach and simulation tools for dynamic phenomena modeling in the considered rotor system is carried out by comparison with data known from open sources. The calculation results prove possibility of numerical simulation of rotor dynamics of this energy machine class with complex structure and control systems of supports and indicate advantages of the proposed approach.

Improving of dynamic performance of a control system of a synchronous drive with field weakening is shown. The controllers of the angular speed of the rotor of a synchronous machine, d and q components of the stator current of the control system have synthesized using the concept of inverse dynamics problems and minimization of local functionalities in the form of acceleration energy and kinetic energy. Mathematical modelling has established that the application of control algorithms of non-traditional structure provides high dynamic characteristics in the entire control range and robustness to the action of parametric and coordinate perturbations. The need of control adaptation and compensation of signals of mutual influence is excluded. Limitation of the output voltage and current of the stator in the second control zone is carried out by using the mode of attenuation of the magnetic field and setting the required trajectory of the angular velocity of the rotor of the synchronous motor.

Sliding mode control systems for electric drives have the highest rates of control quality when closing derivatives of velocity regulation errors. They are characterized by the highest speed and accuracy, insensitivity to the action of parametric, coordinate perturbations and invariance to the form of master actions. An effective structural solution to the problem of constructing systems with flexible feedbacks was made by applying sliding modes in control systems both by the electric drive itself and by its acceleration observer. The N-i switching method provides parametric optimization of controllers.

The purpose of paper is deals with development of neural network control system for induction motor. Such system could be in use to control motor with possible unpredicted behavior, which could be caused due to appearance of unexpected faults during its operation or other factors, when it is essential to keep operational process without stoppage, while prevent motor further damage development and its eventual failure. Proposed control systems are built on the basis of the artificial neural network and provides a list of possibilities for creating control systems that are resistant to the uncertainty of the object and the control process. It was chosen field-oriented control algorithm as a basis for neural controller due to its advantages that can be improved in future. The basic equations and elements of the indirect field oriented control scheme are given. The control scheme is developed basing on feedforward neural network which have two separate input layers: one divided hidden layer and one general hidden layer. Therefore, it is worth exploring such a combination of control methods and its effect on induction motor operation.
本文的目的是研究异步电动机神经网络控制系统的开发。该系统可用于控制由于电机运行过程中出现意外故障或其他因素而可能出现的不可预测行为的电机,在保持电机运行过程不停机的同时,防止电机进一步损坏发展并最终失效。所提出的控制系统建立在人工神经网络的基础上,并提供了一系列可能性,以创建能够抵抗对象和控制过程的不确定性的控制系统。选择面向场的控制算法作为神经控制器的基础,是由于该算法具有可进一步改进的优点。给出了间接场定向控制方案的基本方程和基本原理。该控制方案基于前馈神经网络,该网络具有两个独立的输入层:一个划分隐藏层和一个通用隐藏层。因此,这种组合控制方法及其对感应电机运行的影响值得探讨。

Such system could be in use to control motor with possible unpredicted behavior, which could be caused due to appearance of unexpected faults during its operation or other factors, when it is essential to keep operational process without stoppage, while prevent motor further damage development and its eventual failure. Proposed control systems are built on the basis of the artificial neural network and provides a list of possibilities for creating control systems that are resistant to the uncertainty of the object and the control process. It was chosen field-oriented control algorithm as a basis for neural controller due to its advantages that can be improved in future. The basic equations and elements of the indirect field oriented control scheme are given. The control scheme is developed basing on feedforward neural network which have two separate input layers: one divided hidden layer and one general hidden layer. Therefore, it is worth exploring such a combination of control methods and its effect on induction motor operation.","PeriodicalId":240191,"journal":{"name":"2020 IEEE Problems of Automated Electrodrive.

The paper considers three software tools that allow quickly create electronic educational resources for the introduction of resource-oriented learning of students in higher education. Electronic educational resources of local and open types for students of electrotechnical and electric power specialties in the environment of information system Electronic textbooks Constructor (Constructor Electronic books 1.1.3), Designer of websites Wix.com, SunRav are developed. The definition of the concept of resource-oriented learning as a holistic dynamic process of organization and stimulation of independent cognitive activity of students to master the skills of active transformation of the information environment, which provides optimal use of tandem "student-teacher" consolidated personnel, financial, logistical, teaching and information resources.
本文研究了三种能够快速创建电子教育资源的软件工具,以便在高等教育中引入面向资源的学生学习。开发了面向信息系统环境下电工、电力专业学生的本地开放式电子教育资源电子教材Constructor (Constructor Electronic books 1.1.3),网站Wix.com、SunRav的设计者。将资源导向型学习概念定义为组织和激发学生自主认知活动的整体动态过程,以掌握主动转化信息环境的技能,从而提供最佳利用串联“学生-教师”整合的人力、财力、后勤、教学和信息资源。
