Mechanical mounting of a cable system on offshore platforms (e.g. converter, collection or substation platforms).
A system for transporting electrical energy, in which the electrical conductors are insulated from each other and against earth by material and also protected against mechanical damage with a shared or individual protective covering.
If the system is laid in the earth, it is known as a cable system. If the cable system is used to transport three-phase alternating current, it is known as an AC cable system. If the cable system is used to transport direct current, it is known as a DC cable system.
Indicates a group of offshore wind farms that are grouped close together.
Multiple AC connection lines are brought together on this offshore platform and joined together in such a way that should one of the AC connection lines malfunction between the collection platform and the mainland, the incoming energy from the offshore wind farms can be diverted to other AC connection lines if and where there is spare capacity.
A combined cycle gas turbine plant is a unit for generating electricity (-> generating unit), consisting of a gas turbine generator unit, whose hot exhaust produces steam in a waste heat boiler (with or without the use of a supplementary burner), which is then used to generate electricity in a steam turbine generator unit.
Combined heat and power (CHP) is the term for a special type of thermal power station in which the steam generated by the boiler is used with turbo generators to produce electricity; whereby it is nevertheless possible to extract the steam at designated stages and/or after the turbine stage in the form of so-called back pressure steam to be used as a heat source for industrial processes, district heating and similar. The provision of heat and power is complementary; production can be adjusted to suit demand so that the top priority is either the generation of electricity or producing heat. Simultaneous heat and power generation can also be achieved by means of a gas turbine or an internal combustion engine with a generator, if the exhaust from these facilities are used for heating.
A common mode failure is when one event causes multiple components (operating equipment and generating units) to fail simultaneously.
The term electrical consumer is used to refer to devices, equipment and facilities that consume and transform electrical energy (e.g. into heat, light or work).
The continuous output of a generating unit is the highest level of output produced during standard operation without time limit and which does not affect service life (operating duration) and operational safety of the unit. The continuous output can fluctuate with the seasons (e.g. due to changes in coolant temperature).
A transmission system operator (TSO) is legally obliged to constantly maintain the balance between electricity generation and electricity consumption within their control area, to ensure grid stability (frequency stability of 50 Hertz and voltage stability). In order to do so, they use an automatic power-frequency control, comprising the primary control and the secondary control. The secondary control can also be supported by the manual activation of the minute reserve.
