This paper introduces an alternative to present state-of-the-art electric traction drives powered by HV batteries: a maximum of 330 kW can be deployed mechanically by a LV multi-phase system. Both the ability to switch the electric machine's number of pole pairs and a very efficient 60-phase inverter based on MOSFETs promise a dramatic reduction of losses inside the power train. Investigations on driving cycle efficiencies are carried out for a HV reference system and the novel LV system. The New European Driving Cycle (NEDC) and the driving cycle of the Worldwide harmonized Light vehicles Test Procedures (WLTC) are virtually driven by a common vehicle model in order to determine load profiles for both traction systems. Losses in electric machine, power electronics and battery are estimated and the total vehicle's energy consumption is derived. The novel LV traction system promises a great enhancement in driving range compared to the state-of-the-art HV drive.

Motor stator current signal with noise in current loop would reduce the performance of permanent magnet ac servo system. This paper introduces a new method-matching pursuit which is applied in the denoising of current signal. The proposed method designs the optimal atom based on the similarity between original signal and atoms by using matching pursuit (MP) algorithm. The conventional MP algorithm needs large amount of calculation due to the overcomplete dictionary. To overcome this problem, this parper demonstrates the effectiveness of MP algorithm with undercomplete dictionary. The undercomplete dictionary is consist of sinusoidal atoms after analyzing the characteristic of actual current signal. The signal set partitioning method is proposed to optimize the configuration of dictionary. Simulation and experimental results verify the feasibility and efficiency of the proposed method.

Pore pressure prediction has always been a major challenge in the industry. Various attempts to predict pore pressure have been made by researchers to best describe the trend for a given region. Several methods have been published and claimed to work for many fields. This paper provides a case study for an oil field in Iran in order to check the applicability of some of the methods in this field. Eaton's, Holbrook's and Weakley's method are tried and it is found that Eaton's method provides a closer result, if not an accurate one. The details of the formation are stated to study the nature of these methods in such environment. The compaction exponent of Eaton's method is varied to see the variation in the trend for the field. The compaction exponent of 3.0 is found to work fairly well for depths up to 2600m while exponent value of 0.7 works for depth greater than 2600m. It is inferred that not all methods are applicable globally and there exists a need for further research to develop or modify these methods either qualitatively or quantitatively.

Squirrel-cage induction motors are the most widely used type of electric machinery in industrial applications thanks to their rugged, cheap and robust construction. For the fast prediction of induction motor steady-state performance without the need for time-consuming finite-element analyses, the equivalent circuit parameters of the machine need to be calculated, including rotor slot leakage inductances. This paper, in particular, proposes a new improved analytical formula to determine the rotor slot leakage inductance in squirrel-cage induction motors with rectangular-shaped bars. The formula is obtained by solving Poisson's equation in the slot domain. Results are assessed by comparison against Finite Element Analysis (FEA). The precision of the presented methodology is also compared to that of approximated analytical models available from the literature. The comparison shows that the accurate formula proposed is in excellent agreement with FEA with errors below 2%, while the simplified model generally leads to errors above 10% which increase as the height-to-width bar ratio decreases.

Low-speed high-torque applications, e.g. wind energy generation, favor high number of pole solutions. for traditional radial or axial flux machines this leads to an increase in leakage flux while the power output does not increase. For Transverse Flux Machines (TFM) the increase in power output is proportional to the number of poles. However, large flux leakage is also present in TFMs, reducing their power factor and commercial application. Fast and accurate 3-D models are required to model this flux leakage. Finite Element Models (FEM) comprising a large number of elements are commonly used to calculate the 3-D flux density distribution. This approach is very time consuming with hours for a single solution. A fast and more accurate parameterized model is essential to minimize the machine volume while maintaining the required power factor. In this paper, a design approach is presented to obtain a TFM of a minimum volume with a predefined power factor. An analytical 3-D magnetic charge model is used to model a single magnetic period of the TFM. With the required power factor and the obtained flux due to the magnets the coil dimensions are calculated. The performance of the single magnetic period of the TFM is used to determine the full machine dimensions.

This paper discusses requirements and potential solutions for interoperable wireless charging systems for electric and plugin hybrid vehicles. Such technology is known as resonant magnetic induction charging, also referred to as wireless electric vehicle charging (WEVC). Future requirements for a WEVC system are: low cost, small package, high power transfer and interoperability. This paper discusses interoperability requirements as a key factor for successful deployment of WEVC systems. One key aspect analyzed in this paper is primary and secondary coils requirements as they relate to interoperability. Theoretical and practical studies have been conducted and a suggested interoperable solution is presented.

This paper (Part I), together with a companion one (Part II), deals with the fault-tolerant operation of a 5-phase permanent magnet (PM) brushless DC (BLDC) drive. In particular, this paper proposes an algebraic approach to set up a model of the motor current supply in healthy conditions. Afterwards, a faulty drive is considered with one or more open phases and, by constraining the proposed model with fault-specific conditions, scheduling and magnitude of the currents in the surviving phases are determined automatically as well as the maximum magnitude of the currents and the maximum torque developed by the motor. At last, the paper applies the model to the case of a drive with one open phase fault. In the companion paper the model is applied to the cases of more-than-one open phase faults.

This paper is devoted to a 3D-finite element analysis (FEA) based comparison of two hybrid-excited claw pole alternators (HECPAs) with emphasis on their back-EMF production capability and eddy current losses. From a topological point of view, both machines present the same armature arrangement and are equipped by a toroidal field in the stator. They differ by their second source of excitation which is achieved by a NdFeB-PM in a candidate and by ferrite-PMs in the other. Following an analysis of the flux paths through their magnetic circuits, the machines are the subject of 3D-FEA that enables the investigation of their no-load features. Then, the study is extended to the load operation with a special attention paid to the computation of the iron losses.

The number of the assets that Saudi Electricity Company/National Grid hold have increased tremendously and that increase came from the government spending on the infrastructure. Saudi Electricity Company Shall introduces a tool that show the health of its own assets and that tool is the asset health indices. This tool is going to be an experimental and it is going to highlight the number of the outages for each asset that occurred in 2014 based on the failure mode of each substation equipment's and compare those equipment's on the three departments in Saudi Arabia and they are: (Dammam, Hail & North East, and Qassim) and this is the aim of this paper. Assets health indices are going to introduce different types of assets that Saudi Electricity company/National Grid hold from Power Transformer, GIS, bus bar, etc. The asset health indices could be used as a strategic planning tool to help the maintenance planning during the preventative maintenance of an asset to increase it or decrease the frequency and it could be used as a strategic decision making tool it help the top management on the replacement of an asset. This paper is going under the asset management for power systems on substation life cycle cost optimization.

Selection strategies between multi-power sources are of great importance especially when some of the sources are renewable. In this paper, a selection technique is proposed and described based on fuzzy inference system. A multi-stage fuzzy inference system is proposed for three power sources to reduce computation complexity. The multi-stage fuzzy inference system is adopted in this paper to determine the power source to operate an electrical load (pump) from a hybrid renewable energy source (wind and solar) or a battery back depending upon the availability of the power source(s). Determination of the power source depends upon the wind speed, solar intensity and battery charge percentage. The target is to keep a continuous power flow to the pump giving the highest priority to the renewable sources.
