The following topics are dealt with: sustainable energy; intelligent grid; power system dynamics; power quality; electric vehicle propulsion system; energy management; energy storage systems; operational scheduling; renewable energy; design aspects; HVDC; power electronics; smart grid; control aspects; wind power system; and alternative energy.
The IEEE has recently become very proactive in humanitarian causes; notably by increasing efforts to be “universally recognized for the contributions of technology and of technical professionals in improving global conditions.” One ongoing initiative is the IEEE Humanitarian Technology Challenge's Reliable Electricity project (HTC-RE) [1]. This paper describe a workshop that will illustrate a use...
Electric water heaters can be considered as effective energy storage devices. Since electric water heaters use the electric energy to heat water and store it for future use, thus it is valuable to have control over electric water heaters to use them when the demand for power is low and turn them off during periods of peak demands. This paper presents a centralized controller to control energy consumption...
It is a pleasure to welcome you all to Halifax which is hosting the IEEE Canada Electrical Power & Energy Conference 2010, with the theme “Sustainable Energy for an Intelligent Grid”. IEEE Canada and the IEEE Canadian Atlantic Section are sponsoring the Conference with valuable support from the IEEE Montreal and Ottawa Sections. The conference organizing committee has been busy preparing for this...
Once again Halifax is the host of one of the Canadian Flagship Conferences. This time it is the Electrical Power & Energy Conference 2010 (EPEC '2010). This Conference is a major annual event and is the proud achievement of IEEE Canada, made possible by the efforts of our dedicated and able Conference volunteers. This year the Conference is sponsored by the IEEE Canadian Atlantic Section and the...
It is a pleasure to welcome you to the 4th IEEE Canada Electrical Power and Energy Conference (EPEC) 2010 being held in Halifax, Nova Scotia. The IEEE Canada Electrical Power and Energy Conference is a successor to the annual Electric Power Symposium that was held successfully in Ottawa for a period of seven years. EPEC is now one of the two conferences sponsored by IEEE Canada and even though much...
This paper proposes the application of moving window averaging technique for differential protection of transformer. The instantaneous currents of primary and secondary are transformed by using moving window averaging technique for the window width of one cycle. The steady state values of transformed currents are zero for a sinusoidal signal. However, the presence of harmonic and dc offset may deviate...
Although Nova Scotia produces only 2.8% of Canada's total greenhouse gases (GHG), it has the fourth highest per capita emissions. These emissions come largely from electricity generation and transportation sectors. This is because fossil fuels are the main sources of electricity generation and even in the cleanest GHG reduction scenario fossil fuels will still contribute 60% of the electricity generation...
A major reason for not seeing many solar energy systems utilized for lighting is the high capital cost. This triggered us to design a novel Hybrid Fibre Optic Lighting System. The proposed system relies on the fact that light rays are free and can be harnessed without the use of expensive tracking systems requiring constant alignments. A successful system must respond to the following criteria. The...
This paper presents a proposed modeling and numerical simulation of the speed control ac series motor fed from pulse width modulated ac chopper voltage control. The advantage of this system is its high power factor and less total harmonic distortion factor of the motor current. The digital simulation of this system is described the system behavior in the transient and steady - state conditions. The...
Today's power converter industry is apparently heavily influenced by the need to achieve two important goals: high efficiency and small weight and size. Switching frequency of the converter is a factor that moves the mentioned desired characteristics to opposite directions, improving one and deteriorating the other. A higher switching frequency allows us to use smaller components, but in return it...
One of important subjects in power system restoration that already is not addressed is frequency control. Operators are often concerned with the size of load and generation, which can be safely increased. With the emphasis on higher utilization of power systems, monitoring of its dynamics is becoming increasingly important. This requires information with higher accuracy and update rates faster than...
Conductive EMI noise analysis for switched reluctance machine (SRM), including noise diagnosing by the separator and noise suppression, are presented in this paper. Firstly, the CM and DM noise current loops in SRM's power converter are discussed, and the noise separator based on 0°/180° splitter is employed for noise diagnosis. Then, the EMI filer design and the radiator-ungrounded method are proposed...
In this paper, a new method is proposed to test the conducted electromagnetic interference (EMI) noise of new energy based on analysis the internal structure and measuring principle of line impedance stabilization network. A more accurate measurement of conducted EMI noise in new energy system can be provided by this method in order to design the appropriate filter for conducted EMI noise suppression...
A multifunction Giga hertz Transverse Electromagnetic (GTEM) cell is presented for radiated EMI mechanism diagnosis in this paper. The structure design and measurement principle of the cell are discussed, in the meanwhile, the radiated EMI noise mechanism diagnosis by using GTEM cell is applied for equipment under test (EUT). The multi-pole moment model is employed in GTEM cell to realize EMI measurement...
This paper presents a fuzzy logic controller (FLC) based direct torque control of induction motor (IM) drive to reduce the ripple in developed torque and stator flux. First the effect of amplitude of torque hysteresis band on the torque ripple of an IM motor is discussed. Finally, a strategy to reduce the ripple in the developed torque and stator flux is proposed by controlling the amplitude of the...
