The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.

As the name implies, the DCS is a system of sensors, controllers, and associated computers that are distributed throughout a plant. Each of these elements serves a unique purpose such as data acquisition, process control, as well as data storage and graphical display.

Pressure-regulated volume control (PRVC) is a mode of ventilation in which the ventilator attempts to achieve set tidal volume at lowest possible airway pressure. This mode of ventilation is being commonly used as the initial mode of ventilation in many intensive care units.

A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. ... The blowdown can vary from roughly 2–20%, and some valves have adjustable blowdowns.

A power distribution unit (PDU) or mains distribution unit (MDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data center.

The motive power depot (MPD or railway depot) is the place where locomotives are usually housed, repaired and maintained when not being used. They were originally known as "running sheds", "engine sheds" or, for short, just sheds.

PBRS (Power BI Reports Scheduler) is an on-premise reporting solution that allows users to automate filtration, distribution and delivery of power BI reports and dashboards. The solution can be used by businesses of all sizes across industries.

A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. ... The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.

There is a safety discharge pipe that lets water out of the boiler, if there is a problem with the boiler becoming over pressurised. ... This is called the Pressure Relief Valve Discharge Pipe (or commonly called the 'P.R.V. ') It's a small pipe, which can only be seen on the outside wall of where the boiler is installed.

A thermal power station works on the principle that heat is released by burning fuel which produces (working fluid) (steam) from water. The steam so produced runs the turbine coupled to generator which produces electrical energy.

Generators contain an engine, a fuel system, an alternator and a voltage regulator, as well as cooling, exhaust and lubrication systems.

A Thermal plant uses "burning and combustion" of popular fuels to generate energy which is then converted into electricity. A nuclear plant converts fission or "burning" of non conventional fuel into electricity.

If severe weather threatens a portion of the electric system, it may be necessary for PG&E to turn off electricity in the interest of public safety. This is known as a Public Safety Power Shutoff (PSPS).

During the operation of a power plant, a steam turbine may experience operation at full speed with little or no load (FSNL). ... This work shows that such a simulation can be achieved in the absence of an external drive by running the LP test turbine at higher exhaust pressure and higher mass flow.

Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.

In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant.
