Electric power transmission and distribution systems are extremely vulnerable to adverse weather conditions. It appeats to many people that extteme weather is becoming more frequent and also more violent. It has been suggested that this is due to increased heat and humidity in Earth s environment, leading to increases in both rain and snowfall. The effect of...

If hydrogen-powered fuel cells can be used for small-scale electricity generation, and if technologies to produce hydrogen improve such that hydrogen can be delivered efficiently and cheaply to those small-scale generators, there are possible benefits to the transmission and distribution system (these small-scale generators can use other fuels such as natural gas). 

Open Access - The ability to send or wheel electric power to a customer over a transmission and distribution system that is not owned by the generator (seller) of the power. 

Microturbines, which are typically fueled with natural gas, generate between 25 and 200 kW of electricity. Their small size and relatively low cost allow them to be located near where they are needed. They can operate at very low emission levels and reduce the efficiency losses and environmental impact of large transmission and distribution systems. In this paper, a MCFC is associated with a gas microturbine to produce electric power. 

The Package-Reactor is primarily designed to supply electricity and thermal power for non-electric applications as a stand-alone energy supply system for remote regions, where it is difficult to constmct long-distance power transmission and distribution facilities. 

In addition to the circuit breaker, there have been a number of other SMA appHcations for various functions in electric power generation (qv), distribution, and transmission systems. One such device is a thermal indicator that provides a signal visible from the ground of a hot junction or connector in a distribution yard. Such hot spots occur as a result of the loosening of bus bar connectors owing to cycHc temperature as the electric load varies. In addition to the use of SMA flags as a hot-spot indicators, actuators that automatically maintain the contact force in a bus bar connection have been demonstrated. Based on a BeUeviHe washer fabricated from a Cu—Al—Ni SMA trained to exhibit two-way memory, these washers, when heated by a hot joint, increase their force output and correct the condition. A 30 mm diameter washer 3 mm thick can produce a force of over 4000 N. Similar in purpose... 

Electric power systems can be thought of as being comprised of three important sectors generation, transmission, and distribution. For most utilities, generation capital equipment costs account for approximately 50 percent of total plant in costs. Generation also accounts for close to 75 percent of total operation and maintenance expense. 

The North American electric power transmission system has been described as the largest, most complex machine ever built by humanity. It is a massive network of generating stations, transmission lines, substations, distribution lines, motors, and other electrical loads all interdependently linked for the conversion, transportation, and control of electrical energy. Approximately 60 percent of all energy utilized in the United States passes through the interconnected electric power system. The major goal of the system is to most efficiently and reliably deliver electric power from generating stations to residential, commercial, and industrial consumers.
