turbinspenning

Turbinspenning is a term from Scandinavian languages (turbin + spenning) that is generally used to describe the electrical voltage produced by a generator driven by a turbine, most commonly in hydroelectric, steam and gas-turbine power plants. The expression highlights the link between the mechanical rotation provided by the turbine and the electrical potential generated by the coupled alternator.

In power-generation practice turbinspenning depends on generator design, rotational speed, magnetic-field excitation and load conditions. It is actively regulated by excitation systems and automatic voltage regulators to maintain stable output under changing load and network conditions. The generated voltage is usually transformed and synchronized before being dispatched to the transmission grid.

Monitoring and control of turbinspenning are part of normal plant operation. Instruments such as voltmeters, phasor measurement units and SCADA systems track voltage magnitude, frequency and phase to ensure compliance with grid codes and to coordinate protection systems. Voltage disturbances originating at the turbine-generator unit can affect power quality and grid stability and are managed through control, protection and auxiliary equipment.

Safety and reliability considerations include insulation coordination, earthing, surge protection and maintenance of excitation and control systems. In some contexts the compound term may also be used more broadly to refer to mechanical stresses within turbine components, but its primary technical usage denotes the electrical voltage associated with turbine-driven generation.
