Abstract
The wind power system comprises an installation (1) for generating electrical power from wind by means of at least one power generating turbine arranged to be rotated by wind, and a control system (2) including a power controller (22). The power controller (22) is configured to keep the magnitude of the total current below a pre-set maximum magnitude (Imax).
Claims18
Wind power system, comprising an installation (1) for generating electrical power from wind by means of at least one power generating turbine arranged to be rotated by wind, and a control system (2), said control system including a power controller (22) for controlling the supply of electrical power from said wind power system to a network (4) for distribution of electrical power to a plurality of consumers, wherein the power controller comprises means for controlling a current supplied towards said network by said wind power system in accordance with at least one input parameter (223),
- characterised in that
- the power controller (22) is configured to keep the magnitude of the total current supplied towards the network below a pre-set maximum magnitude (Imax),
- and in that the control system is arranged to establish, in view of a measured network voltage and in view of the active power that is supplied towards the network, a maximum amount of reactive power (Qmax) that can be supplied towards said network, said maximum amount of reactive power being selected so that said total current will not exceed said pre-set maximum magnitude (Imax).
Method of operating a wind power system comprising an installation (1) for generating electrical power from wind by means of at least one power generating turbine arranged to be rotated by wind so as to supply current towards a network (4) for distribution of electrical power to a plurality of consumers,
- characterised in that
- it comprises the step of keeping the magnitude of the total current supplied towards the network below a pre-set maximum magnitude (Imax),
- and in that
- it comprises the step of establishing, in view of a measured network voltage and in view of the active power that is supplied towards the network, a maximum amount of reactive power (Qmax) that can be supplied towards said network, said maximum amount of reactive power being selected so that said total current will not exceed said pre-set maximum magnitude (Imax).
