Fluidized Bed Combustor

A novel closed-cycle gas turbine power system is now under development by the GWF Power Systems Company for cogeneration applications. Nominally the system produces 5 megawatts (MW) of electric power and 80,000 lb/hr (36,287 kg/hr) of 1000 psig (6895 kPa) steam. The heat source is an atmospheric fluidized bed combustor (AFBC) capable of using low-cost solid fuels while meeting applicable emission standards. A simple, low-pressure ratio, single spool, turbomachine is utilized. This paper describes the system and related performance, as well as the development and test efforts now being conducted. The initial commercial application of the system will be for Enhanced Oil Recovery (EOR) of the heavy crudes produced in California.

Phasor Measurement

The widespread diffusion of Phasor Measurement Units (PMUs) is a becoming a need for the development of the “smartness” of power systems. However, PMU with accuracy compliant to the standard Institute of Electrical and Electronics Engineers (IEEE) C37.118.1-2011 and its amendment IEEE Std C37.118.1a-2014 have typically costs that constitute a brake for their diffusion. Therefore, in this paper, the design of a low-cost implementation of a PMU is presented. The low cost approach is followed in the design of all the building blocks of the PMU. A key feature of the presented approach is that the data acquisition, data processing and data communication are integrated in a single low cost microcontroller. The synchronization is obtained using a simple external Global Positioning System receiver, which does not provide a disciplined clock. The synchronization of sampling frequency, and thus of the measurement, to the Universal Time Coordinated, is obtained by means of a suitable signal processing technique. For this implementation, the Interpolated Discrete Fourier Transform has been used as the synchrophasor estimation algorithm. A thorough metrological characterization of the realized prototype in different test conditions proposed by the standards, using a high performance PMU calibrator, is also shown.

Economical Consideration

Incremental consumption of electrical energy, reduction of fossil fuel resources and environmental pollution problems caused by them are the main reasons, which tend the managers and officials in countries energy sector to develop use of renewable systems. In the not-too-distant future the use of renewable energy such as wind and solar will be very important and will play predominant role in economic indices of power systems. In recent years, technological advances in renewable energy and increasing price of petroleum products promote system managers to use low-cost and low-emission energy resources in form of hybrid systems and widespread propagation of electricity generation have been developed in remote areas. In Hybrid systems two or more sources of renewable energy is typically adopted, which increases the reliability of these systems. In this paper, the technical and economical consideration of a wind and solar hybrid system to supply electrical energy for a number of remote users (aid and medical emergency Shelter in Yazd) is provided. In order to investigate optimization and economic analysis of the proposed hybrid system, the HOMER software is used.  The results of Simulation in HOMER software show that Solar cells and wind systems with average generation power of 896 kWh/yr. and 343 kWh/yr., consist proportion of 72 and 28 percent of the total generated energy respectively, which are dedicated to satisfy the loads

Electric Bicycles

Battery powered electric bicycles and scooters, replacing the heavily polluting scooters with two-cycle internal combustion engines, provide zero-emission transportation for many parts of the world. Annual global sales of electric bicycles have risen from 36,000 in 1993 to over 500,000 in 1999 and to multi-millions today. To facilitate the development of new electric bicycles, a computerized electric bicycle testing facility has been created. Standardized testing cycles for quantitatively measuring the performance of electric bicycles have been developed. Testing results of three representative electric bicycles using the newly introduced electric bicycle testing methods and testing facility are presented. The development of a low-cost, fully Adaptable Electric Bicycle Power System (AEBPS) designed to be quickly adapted to a regular bicycle is also presented. The AEBPS can be attached to a regular bicycle in less than ten minutes, and removed in under five minutes. Performance of a converted bicycle using the AEBPS is evaluated and compared with representative commercial electric bicycles. The work forms the foundation for systematically evaluating different electric bicycle designs and for carrying out design optimization of electric bicycle power systems suitable to different markets and needs.

Process Heating

The benefits of Concentrated Solar Power (CSP) systems include the ability to use them in combined cycles such as Combined Cooling Heat and Power (CCHP), and direct AC power generation. While this is done with success for utility scale power production, there are currently no systems offering this for residential scale, distributable power systems. In prior research, a low-cost high-temperature cavity receiver for a wide variety of applications was developed by employing silicon carbide [1]. The proposed design takes advantage of exclusive manufacturing techniques for ceramics such as machining in the green state and sintering multiple simple parts together to form a single complex part. Serious consideration has gone into designing a receiver that will be universally compatible with a number of applications. Some applications include using the receiver in a combined cycle power generation, as a chemical reactor, or for combined heat and power. The focus of this research is to analyze system metrics for a CCHP dish-Brayton system that is feasible for residential scale use. Preliminary research shows that an adequately sized system could provide a single family home with 2.5 kW of electricity and another 7 kW of process heating that could be used for absorption chilling or hot water and space heating. Cost analysis on the system will be performed to quantify its economic viability. Results on the analysis for multiple process heating applications will be presented along with the proposed design.
