RELIABILITY ANALYSIS OF IGBT MODULES OF MULTILEVEL INVERTERS OPERATING IN HOSTILE ENVIRONMENTS

IEEE
Throughout the industry, pulse width modulation voltage source inverters (PWM-VSI) are commonly utilized with adjustable speed drives (ASD) to control, most commonly, induction motors. Especially in the mining and petroleum industries, long cables connecting motors and inverters are often present, which can cause several problems. As an innovative solution, an alternative system configuration has been previously proposed, in which the rectifier is kept in its typical location, and the inverter bridge and DC bus capacitors are installed near the driven motor. Long cables are used as a DC transmission line, mitigating the high-frequency problems resulting from the inverter-cable-motor interaction. On the other hand, new concerns regarding the reliability of the power devices arise once the inverter is installed in harsh ambient conditions. In this context, this work proposes a reliability analysis of such drive configuration, applying the physics of failure (PoF) approach combined with the design for reliability (DfR) methodology to carry out the design adjustments to achieve the reliability required for the application, focusing on the inverter IGBT modules. Moreover, this paper will evaluate widely accepted multilevel inverter topologies and modulation strategies, verifying those capable of minimizing implementation costs and ensuring adequate reliability indexes for the system—aiming to enable the commercial use of this promising configuration. The results show that a three-level active neutral point clamped inverter (3L-ANPC) topology applying two pulse width modulation (PWM) strategies and 400 A – 6.5 kV IGBTs would be the most appropriate from this study's reliability and feasibility analyses.


Tool for the Assessment of the Savings in the Cable Acquisition When Employing DC Transmission in Long Distance Drives

Throughout different stages of the mining processes, alternating current (AC) motors powered by pulse width modulation (PWM) converters are employed, typically connected by extensive cable lengths. While these drives bring forth significant advantages, they also give rise to challenges associated with high-frequency problems, which, in turn, reduce the operational lifespan of the system components. Off-the-shelf solutions, involving the incorporation of passive filters, tend to adversely affect both the cost and efficiency of the system, justifying research for new alternatives. A recent proposal suggests a distinctive approach, wherein the frequency converter is divided into its rectifier and inverter units. The former is situated in its original location, while the latter is positioned close to the load. Consequently, the drive system operates with direct current (DC) for electric power transmission. This innovative topology not only eliminates the high-frequency problems but also substantially enhances efficiency while reducing costs of the transmission. Prior research has demonstrated the potential of this alternative drive topology, particularly through case studies in low- and medium-voltage systems within mining plants. In this paper, the economic and energy efficiency potentials of such DC transmission drives regarding the power transmission are examined using reference graphs that offer insights beyond conventional case studies. These graphs represent decision-making tools, allowing for a quick and accessible assessment of the economic viability of the alternative topology for a wide range of powers and drive distances. The main aspects related to the methodology, along with relevant technical discussions, are addressed.

Caio Eduardo Silva, André M. Alzamora, Marco T. A. Êvo, and Hélder de Paula
Institute of Electrical and Electronics Engineers (IEEE)
Especially in the mining industry, Pulse Width Modulated Voltage Source Converters (PWM-VSC) are commonly used to drive induction motors at long distances from the inverter. However, this can cause unwanted high-frequency phenomena due to the long cables used for the converter-to-motor connection. A new configuration has been proposed to address this issue, keeping the rectifier in its original location while installing the inverter bridge close to the motor terminals. However, this new configuration can compromise the inverter's lifetime in hostile environments. This paper presents a study on the reliability of DC-Link capacitors for Three Level Neutral Point Clamped (3L-NPC), Three Level Active Neutral Point Clamped (3L-ANPC), and Five Level H-Bridge Neutral Point Clamped (5L-HNPC) inverter topologies in these environments, using methodologies based on Physics of Failure (PoF) and Design for Reliability (DfR).


Electrostatic Shielding for Bearing Current Mitigation-An Analysis of its Thermal Impact on the Motor
Marco Túlio Alves Êvo, Arismar M. G. Júnior, Caio Eduardo Silva, and Hélder de Paula
Institute of Electrical and Electronics Engineers (IEEE)
This work presents a study on the use of electrostatic shields to reduce bearing currents (both Electrostatic discharge machining and circulating currents), focusing on its thermal impact on the motor operation. 2-D finite element models are utilized to analyze the temperature distribution inside the coil winding slot of motors both with and without shielding. The results show that the shielding device can be used with a negligible influence on the temperature rise inside the slot. In addition, it is demonstrated that for some shield configurations, the stator winding eddy current loss can be attenuated. In such cases, the shield presence can also lead to a temperature reduction in the stator conductors. Furthermore, the developed models can be expanded to be used in the analysis of any other motor equipped with this type of solution, aiding the design and implementation of the shielding device. Keeping in mind that the majority of the motor failures are due to bearing problems, this article contributes to the industry by addressing issues closely related to the reliability topic, such as solutions to increase the motor availability, which is the very case of the shielding device.

Institute of Electrical and Electronics Engineers (IEEE)
In a previous work, the authors addressed electrostatic shielding to reduce the bearing discharge currents (electrostatic discharge machining currents - EDM). In order to expand the application of such a shielding device, this article presents an analysis of its use to reduce the inverter-induced circulating bearing currents on induction machines. Employing finite element analysis (FEA), 2D, and 3D models were developed to clarify the tradeoff between the shield effectiveness and the associated additional heat losses and motor efficiency reduction, considering different geometric arrangements and materials for the shielding device construction. The results provide very good guidelines for the shield design, contributing to its practical application viability. It is shown that it is possible to design a shielding configuration that achieves a high mitigating level with a negligible impact on the motor efficiency and developed torque. Furthermore, comparing calculation models of different complexities, the article also shows the importance of representing all capacitive couplings inside the motor and the non-uniform current distribution in the shield to determine its effectiveness. Since a large fraction of the motor failures are caused by bearing currents, this article can provide benefits to key topics for industry, such as equipment reliability and availability.


Evaluating a New Configuration for Medium-Voltage Drive Systems in a Mining Plant
André M. Alzamora, Caio Eduardo Silva, Marco T. A. Êvo, and Hélder De Paula
IEEE
Large AC motors are ubiquitous in the mining industry, and these often require medium-voltage (MV) converters. Generally, long cables provide the connection between the variable speed drive (VSD) and the motor, which increases problems involving high frequency currents and overvoltages. These undesired phenomena are attenuated by large, heavy and expensive inverter output filters. As an alternative solution to such problems, the authors have proposed, in previous works, the separation of the frequency converter into its rectifier and inverter units, where the rectifier remains in its original location and the inverter is placed beside the motor, thus establishing a DC transmission link through the long cable. Such a configuration naturally (i) mitigates the high-frequency phenomena, (ii) reduces the voltage drop along the cable, and (Hi) can result in substantial copper savings. Until the present moment, the evaluations performed on the proposed topology was aimed at low voltage mining applications, which have shown excellent results. However, since MV drive systems are common in the mining industry, the proposed drive topology should also be analyzed considering this application. In this way, this paper evaluates the copper and energy savings obtained through this alternative drive topology by means of a case study involving three MV motor drive systems situated in a mining plant.

Especially in the mining industry, Pulse Width Modulated Voltage Source Converters (PWM-VSC) driving induction motors at long distances from the inverter is common. Due to the long cable used for the converter-to-motor connection, several unwanted high-frequency phenomena occur. A new configuration for these motor drive systems was previously proposed to address this situation. The new configuration involves keeping the rectifier in its original location, while the inverter bridge is installed close to the motor terminals, and long cables are used as a DC transmission line. The environment in which the inverter will now be located is more hostile and can compromise the inverter’s lifetime. This situation creates new concerns about the system’s reliability, despite the various advantages of this new configuration. This paper presents a study on the reliability of the DC-Link capacitors for Three Level Neutral Point Clamped (3L-NPC) and Three Level Active Neutral Point Clamped (3L-ANPC) inverter topologies when operating in aggressive environments. For this purpose, methodologies based on Physics of Failure (PoF) and Design for Reliability (DfR) were used. In this sense, an investigation was conducted to find the configurations best suited to improve the solution regarding reliability, cost, energy, and volume.


Selection of attributes for partial discharge localization in transformer windings
Arismar M. G. Júnior, Marco Túlio A. Evo, Caio Eduardo Silva, and Hélder De Paula
IEEE
Nowadays, machine learning methods have been widely used in the detection, diagnosis, and localization of Partial Discharges (PDs) in power transformers, such a fact that allows early identification of failures in the insulating system and the proper scheduling of maintenance activities. Before the classifiers training stage, however, features extraction and selection from the PDs signals is a fundamental step, procedures directly related to the models' validation performance, and that can avoid their overfitting. Therefore, in this paper, methods for features extraction and selection are investigated, regarding the PDs location between layers and sections of the transformers windings. For this purpose, features extracted from the PDs' high-frequency current signals were selected by the Stepwise, SVM-RFE, and CasCor methods, being the resulting subsets applied in the training of SVM classifiers constituting a localization system. The results show that the features subset arising from the CasCor selection method provides SVM models with better performance for locating PDs, either between layers or sections of the winding.

Especially in the mining industry, pulsewidth modulation voltage source converters driving induction motors located far away are often present. In this case, due to the long cable used for the converter-to-motor connection, several unwanted high-frequency phenomena are generated. In this context, a new configuration for motor drive systems was proposed, in which the rectifier is kept in its original position and the inverter bridge is installed close to the motor terminals, being the long cable used as a dc transmission line. Since this environment is always more hostile and can compromise the inverter lifetime, new concerns regarding the system reliability arise, despite the various technical-economic advantages of this new configuration. In this way, this article presents a comprehensive comparison of commercially widely accepted multilevel inverter topologies, searching for the best technical features for the aforementioned dc transmission applicability/feasibility. Simulations were performed assessing several essential quantities/indexes, with a major focus on reliability. Then, a discussion was made seeking those sets that could minimize the implementation costs and improve the system reliability, concerning the insulated gate bipolar transistor (IGBTs) and the metalized film and aluminum electrolytic capacitors of the dc link.

Em toda a indústria, mas principalmente no setor de mineração, siderurgia e extração de petróleo, conversores de frequência do tipo inversor fonte de tensão (VSI) e utilizando modulação por largura de pulso (PWM) são amplamente utilizados para o controle de velocidade e conjugado de cargas motrizes. Com frequência, os motores de tais sistemas de acionamento são alimentados através de cabos longos, sendo que, em tal configuração, diversos fenômenos, diversos fenômenos indesejados de alta frequência (e.g., sobretensões transitórias nos terminais dos motores, danos aos rolamentos da máquina, entre outros) são originados. Neste contexto, foi proposta em trabalhos anteriores uma nova configuração de sistema de acionamento, onde o retificador permanece em seu local original e a ponte inversora passa a ser instalada próxima ao motor acionado, cujo ambiente é sempre mais hostil e pode comprometer a sua vida útil. Apesar das inúmeras vantagens desta nova configuração, novas preocupações se fazem presentes, no que diz respeito à sua confiabilidade. Desta forma, este trabalho trata-se de uma revisão de literatura, que tem como objetivo discutir, de maneira qualitativa, os fatores de estresse tipicamente presentes nos ambientes industriais analisados, os mecanismos de falhas dos componentes mais críticos de um conversor, os possíveis problemas da sua instalação nestes ambientes severos e as soluções em potencial para minimizar os seus efeitos danosos.

Matrix Converters: Evaluation of a Technique for the Common Mode Voltage Reduction Aimed at Long Cable Motor Drive Systems
Andre M. Alzamora, Isabela O. Zaparoli, Marco Tulio A. Evo, Caio Eduardo Silva, and Helder de Paula
IEEE
Motor drive systems in mining facilities usually require long cables to connect the converter to the motor. The result is the widely known occurrence of transient overvoltages on the motor terminals, in both differential and common voltages, as such this (i) increases the dielectric stress over the windings and (ii) produces the voltage induced in the motor shaft, which goes on to generate EDM discharges and damage to the motor bearings. In this context, to deal with (ii), in this paper, a modified modulation technique for the common mode voltage reduction in matrix converters is evaluated. Simulations were developed in MATLAB/Simulink employing sophisticated models for the converter, cable, motor and transformer, which are able to represent their behaviors in a wide frequency range. From the obtained results, the advantages and drawbacks of the modulation method under investigation are highlighted and discussed. One of the conclusions is that the differential transient overvoltages are magnified when the modified modulation control is used, in contrast to the common mode reduction provided by it. Due to this trade-off between these two undesired phenomena, the intended application is what will go on to define the feasibility of the investigated technique.
