An idealized representation of the four kinds of reserve power and the time intervals after an unexpected failure that they are in use. [1]In electricity networks, the operating reserve is the generating capacity available to the system operator within a short interval of time to meet demand in case a generator goes down or there is another disruption to the supply.
Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time.
In an electrical grid, the short circuit ratio (or SCR) is the ratio of: the short circuit apparent power (SCMVA) in the case of a line-line-line-ground (3LG) fault at the location in the grid where some generator is connected, to: the power rating of the generator itself (GMW).
The arrival process describes the manner in which entities join the queue over time, often modeled using stochastic processes like Poisson processes. The efficiency of queueing systems is gauged through key performance metrics. These include the average queue length, average wait time, and system throughput.
LT – Linear Time or Lag Time; LTA - Land Treatment Area; L&T – Load and Test; LTC – Long Thread and Coupled; LT&C – Long Thread and Coupled; LTHCP – Lower Tubing Hanger Crown Plug; LTI(FR) – Lost Time Incident (Frequency Rate) LTP – liner shaker, tensile bolting cloth, perforated panel backing; LTX – Low temperature extraction unit
In mathematics and economics, a corner solution is a special solution to an agent's maximization problem in which the quantity of one of the arguments in the maximized function is zero. In non-technical terms, a corner solution is when the chooser is either unwilling or unable to make a trade-off between goods.
A graph showing the impact on some endogenous variable, over time (that is, the multipliers for times t, t+1, t+2, etc.), is called an impulse-response function. [2] The general method for calculating impulse response functions is sometimes called comparative dynamics.
The access time or response time of a rotating drive is a measure of the time it takes before the drive can actually transfer data. The factors that control this time on a rotating drive are mostly related to the mechanical nature of the rotating disks and moving heads. It is composed of a few independently measurable elements that are added ...
