A large section of the upper reservoir failed, draining over a billion gallons of water (4 million m³) in less than half an hour. There were no fatalities, but five people were injured. The failure resulted in permanent damage to the surrounding landscape and power generation did not resume until 2010. 2005 [13] [14] [15] Itaipu Dam: Paraná (BR)
Forced outage rate (FOR or FOAR) of a power station unit is the probability that the unit will not be available for service when required.. FOR is defined as the number of hours the unit is on forced outage over the total number of hours in a year (which is the sum of hours the power station is available for service and hours the power station is in forced outage).
An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power ...
To provide a black start, some power stations or plant have small on-site diesel generators, normally called the black start diesel generator (BSDG), which can be used to start larger generators (of several megawatts capacity), which in turn can be used to start the main power station generators. Generating plants using steam turbines require ...
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. [1] Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost ...
A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. [1] This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared. [2]
Employees were dismissed, however, when water covered the parking lot and the adjacent road, and the plant lost power. President Joe Biden has approved an emergency declaration for Tennessee.
The greatest variation in the design of steam–electric power plants is due to the different fuel sources. Almost all coal, nuclear, geothermal, solar thermal electric power plants, waste incineration plants as well as many natural gas power plants are steam–electric. Natural gas is frequently combusted in gas turbines as well as boilers.
