Abstract:
In this paper, a Hopfield Lagrange network (HLN) method is applied to solve the optimal load dispatch (OLD) problem under the concern of the competitive electric market. The duty of the HLN is to determine optimal active power output of thermal generating units in the aim of maximizing the benefit of electricity generation from all available units. In addition, the performance of the HLN is also tested by using five different functions consisting of the logistic, hyperbolic tangent, Gompertz, error, and Gudermanian functions for updating outputs of continuous neurons. The five functions are te

The paper summarizes exhaust emissions measurements on two diesel-electric locomotives and one diesel-hydraulic railcar, each tested for several days during scheduled passenger service. While real driving emissions of buses decrease with fleet turnaround and have been assessed by many studies, there are virtually no realistic emissions data on diesel rail vehicles, many of which are decades old. The engines were fitted with low-power portable online monitoring instruments, including a portable Fourier Transform Infra Red (FTIR) spectrometer, online particle measurement, and in two cases with p

Abstract The paper presents a thermoeconomic analysis of three pressure level reheat combined cycles derived from existing steam power plants. The gas turbine employed is an intercooled gas turbine, proposed and investigated in the Collaborative Advanced Gas Turbine program by the major aero-engine manufacturers and international electric and natural gas industry sponsors. The steam power plants to repower are conventional steam power plants of three different sizes, 320 MW, 160 MW and 70 MW, easily found in Italy. Firstly, a thermodynamic analysis is performed for the different repowered plan

Abstract:
Centrifugal chillers using CFC’s were made in India in the capacity range from 150 TR to approximately 700 TR. Currently, there are around 500 units operating in India ranging in age from 10 to 30 years. All of these units will have to be replaced eventually since CFC’s are to be phased out by 2010 in Article 5 countries as per Montreal Protocol. The World Bank has made a detailed study of the issue and proposed a Global Chiller Replacement Project whereby the old units will be replaced by the current generation of energy-efficient chillers using non-CFC refrigerants.

DC High Speed circuit-breakers (DC-HSCB’s) and Protective Relays (PR’s) are present in all sorts of rail infrastructure. National or urban railways, tramways or metro’s, they all rely on this equipment to protect them from disastrous situations. The circuit-breakers can be installed either on board of the trains or on the trackside, in traction power substations. Protection Relays are, in most cases, part of the fixed installation. Needless to say that the DC-HSCB and PR are critical parts of the rail infrastructure. In the best case a faulty unit can cause the trains to stand still, in the wo

Low temperatures stimulate the mechanisms of human immunity, which is due to the influence of the pituitary gland on the thymus and adrenal glands, responsible for cellular and humoral immunity. For people who work outdoors, the prolonged action of moderate cold on the body is the most widespread form of hardening from a practical point of view. At the same time, cold air currents, directed towards certain segments of the body, such as the neck, shoulders, legs, present risk factors for human health, and it is necessary to avoid them.
