Mining trucks are sophisticated equipment that must operate continuously under difficult environmental conditions at the limit of their capacities. Hence, any tool that helps to evaluate the stress of mechanical components and/or overloading of electrical components will be of great benefit. This paper presents the development of an integrated electric-mechanical hauling truck model capable of determining all the variables of interest of the powertrain, traction and retarding systems. The developed model is first evaluated on idealized uphill and downhill routes, giving a clear view of the behavior of each component. These results are applied to the analysis of a complete downhill-uphill truck cycle in a copper mine. Finally, selected sectors of the mine road are evaluated to compare field records to the corresponding signals of the developed model. Results show a good agreement with errors between 2% and 5%.

In this paper, an optimal decentralized controller is designed for the load frequency control of a microgrid with multiple synchronous generation systems and renewable energy sources in the islanded mode of operation. The decentralized controller includes multiple proportional-integral (PI) controllers designed and optimized simultaneously by using a classical descent-direction Quasi-Newton based optimization technique. The optimal decentralized PI controller accounts for the dynamic coupling among the areas of the microgrid without any communication links required among the PI controllers, and hence improves the frequency control performance as compared to a set of optimal linear-quadratic Gaussian (LQG) integral controllers of eighth order which are designed independently. Simulation results confirm the effectiveness of the proposed decentralized control approach.

In this paper, a reduced order state observer for DFIG is designed that estimate the states with just using DFIG's stator voltage and power measurements. Further, the proposed state observer is used to provide two control strategies for Rotor Side Converter (RSC) of DFIG a) state estimator based state feedback control and b) state estimator based vector control. The state observer and controllers were tested for varying wind conditions using a full order dynamic model of DFIG with a real-time simulation platform. The results verify that the proposed state observer can augment existing control for DFIG with better tracking of the system output without the need for feedback measurements, and at the same time it can reduce the controller design complexity. Also, these state estimator based controllers eliminate the need of rotor current sensors for DFIG control.

For a variety of reasons, it is becoming an increasingly common requirement for ships to shut down ship generators and connect to high voltage shore power for as long as practicable while in port. Ship electrical equipment shall only be connected to shore supplies that are able to maintain harbor distribution system voltage quality. Voltage drop, which is produced by the possible loading conditions of a ship when connected to a shore supply, may result in unsatisfactory operation of, and damage to, electrical and electronic equipment on board and thus, must be considered in the harbor distribution system design in order to comply with the requirements of international standards. A simple and fast method able to estimate the expected magnitude of voltage drops and provide information about the effectiveness of the various mitigation methods is essential. This paper presents the methodology and results for evaluation of the voltage drops of a practical harbor electrical distribution system with high voltage shore connection (HVSC). The potential voltage drops of the implemented HVSC are quantified using standard analytical formulas. Sensitivity analysis is performed to determine the critical parameters that significantly affect voltage drops. The parameters that have great improvement benefits should have high priority for implementation in other distribution systems with HVSC. The results obtained in this paper can provide engineers with useful information regarding the actual magnitude of voltage drops, as well as on the effectiveness of mitigation options for voltage drops, which would greatly enhance HV shore supply quality.

A novel design of pose deformation system for mobile robots is presented in this paper, which transforms the position of moveable wheels by pushrods mechanism to adapt rough road conditions. A simulation method, which combined the control schemes and physical structures through the Bond Graph and Simulink, is utilized to model the pose deformation and running control process of the proposed design. Based on the model, the responses to step disturbance of the deformation control system are analyzed, then different failure modes of the pushrods are added to simulate the reliability. At last, the effectiveness of the proposed deformation system to improve reliability is verified by simulation results.

This paper analyzes the influence of frequency and voltage variation over the commutation of thyristors in high power cycloconverters. The analysis demonstrates that frequency and voltage variations can cause commutation failures generating significant damages in cycloconverters. In addition, the paper shows how to determine the maximum frequency and voltage variations that will not affect commutation between thyristors, information that can be later used for the correct setting of protection relays. The analysis is complemented with simulated results using data obtained from high power thyristors used in commercially available cycloconverters. Finally, a commutation failure in a 15 MW grinding mill cycloconverter drive is presented and analyzed.

This paper presents control schemes for efficient operation of renewable energy based islanded microgrid integrated with Energy Storage System (ESS) and diesel generator as a backup source. In the proposed control algorithm, ESS and diesel generator are operated in various control modes based on the state of charge (SOC) level of the battery ESS. The ESS system is categorized into three states as normal, warning and critical based on the SOC level. During the normal state, ESS system is operated as the main source while in the warning state it will operate along with diesel generator in peer to peer mode and in the critical state diesel generator operates as the main source to regulate the islanded microgrid. The detailed model of the islanded microgrid system is developed in MATLAB/Simulink™, and the simulation results of the operation of the system in various modes and transition between them are presented in the paper.

This work develops a novel sinusoidal charging strategy for use in light electric vehicles (LEVs). To generate a sinusoidal charging current, the switching frequency of the series-resonant converter is less than half of the resonant frequency. Thus, the series-resonant converter is operated in discontinuous current mode (DCM) to achieve the zero-current-switching (ZCS) condition. As a result, high energy conversion is ensured. Novel sinusoidal charging topologies with a simple structure, low cost, easy control, and high efficiency are presented for the battery energy storage systems (BESSs) of LEVs. The operating principles and design procedure of the novel sinusoidal charger circuits will be analyzed in detail. The optimal properties of the resonant components are derived from the novel sinusoidal charger circuit configuration. Simulation and experimental results are obtained for a laboratory prototype and demonstrate the feasibility of the proposed strategy. Finally, prototypes of the novel sinusoidal charger circuit that is designed for LEVs with a 48V-12Ah lead-acid BESS are constructed and tested to confirm the theoretical predictions. The maximum charging efficiency of the charging period is 95.95%. Experimental results reveal the satisfactory performance of the novel high-frequency sine-wave charging strategy, which is particular appropriate for BESSs in LEVs.

An electrode-based through-the-earth (TTE), or linear TTE, communication system sends its signal directly through the earth overburden of a mine by driving an AC current into the earth. The resultant current, present at the receiver, is detected as a voltage and communication is established. The electrode-based TTE system may achieve a considerably large transmission range >305 m (1000 ft). This kind of system may be implemented for emergency communication close to an area such as a refuge alternative or other strategic location to establish communication between underground miners and the surface. Since it does not rely on extensive infrastructure underground, this communication would provide an alternate path out of the mine. Given the attenuation characteristics of the earth-which is the major factor determining the performance of TTE systems-the receiver sensitivity, transmitter antenna length and orientation, working frequency, and transmitted current required for communication can be estimated and determined. In an effort to estimate the earth attenuation, the analytic solution for the electrical field distribution of an electrode-based TTE communication system in a homogenous half-space is derived. A prototype system was built and tested at a mine site. The test data is compared with the modeling results, and a close agreement is found between them.

Many thermal solar power plants use thermal oil as heat transfer fluid, and molten salts as thermal energy storage. Since the engineering of these plants is relatively new, regulation of the thermal energy storage system is currently achieved in manual or semiautomatic ways, controlling its variables with proportional-integral-derivative (PID) regulators. This paper explores into the results obtained with different control strategies implemented on a complete model of energy storage systems based on molten salt. By doing so, the optimal control method can be identified.
