Load following power plant

energy

A load following power plant, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day.

Load forecast

energy

Load forecasting is a technique used by power companies to predict the power or energy needed to balance the supply and load demand at all the times.

Load Line Convention

marine

see International Convention on Load Lines, 1966.

Load line mark

marine

Ships must have a load line mark located amidships on both sides to indicate the maximum allowable draught under specified conditions (geographical and seasonal).

Load management

energy

Load management, also known as demand-side managemen, is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output.

Load profile

energy

A load profile is a graph of the variation in the electrical load versus time.

Load regulation

energy

Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Load shedding

energy

A process of reducing the load when a transmission system is unable to meet the peak demand requirements.

Load variation curve

energy

A chart that shows the variation in demand for energy from consumers over a time period.

Loader

marine

Shore-based equipment used to load the holds of a cargo ship (e.g. conveyor belt).

Load-frequency control

energy

Load-frequency control is employed to allow an area to first meet its own load demands, then to assist in returning the steady-state frequency of the system, Δf, to zero.

Loading and Stability Manual

marine

According to SOLAS Convention every passenger ship regardless of size and every cargo ship having a length L of 24m and upwards, must be provided with such information...

Loading arms

marine

Transfer units between ship and shore for discharge and loading oil or any liquefied gas; there are articulated all-metal arms (hard arms) or a combination of metal arms and hoses.

Loading conditions of bulk carrier

marine

Alternate hold loading condition, Heavy cargo, such as iron ore, is often carried in alternate cargo holds on bulk carriers.

Loading instrument

marine

An instrument by means of which it can be easily and quickly ascertained that the still-water bending moments and shear forces will not exceed the specified values in any load or ballast condition.

Loading overall

marine

The loading of cargo or ballast “over the top” through an open-ended pipe or by means of an open-ended hose entering a tank through a hatch or other deck opening, resulting in the free fall of liquid.

Loading rate

marine

The rate of loading of a particular type of shore-based equipment (measured in tons/hour).

Load-loss factor

energy

Load-loss factor is a factor which when multiplied by energy lost at time of peak and the number of load periods will give overall average energy lost.

Loads

marine

A ship at sea encounters many types of loads and forces simultaneously, such as wave-induced bending and shear torsion, impact of waves on the sides, deck and bottom, static loads from cargo and the sea, as well as sloshing.

Local distribution company

energy

A local distribution company is a distribution company that maintains the portion of the utility supply grid that is closest to the residential and small commercial consumer.
