Abstract
A wind power plant includes a control system operatively connected to switchgear devices of a plurality of wind turbine clusters, and wherein the control system is configured to identify the existence of a no-generation condition affecting at least one of the plurality of wind turbine clusters; control the switch status of the switchgear devices, based on the identification, to control the connection status of each of the plurality of wind turbine clusters to an inter-cluster power network so as to reduce no load losses of the wind turbine clusters.
Claims18
A wind power plant comprising:
- a plurality of wind turbine clusters,
- wherein each wind turbine cluster includes a plurality of wind turbine generators connected to a connection station by an intra-cluster power network, each wind turbine generator being connected to the connection station by a respective one of a plurality of first switchgear devices of the connection station;
- and
- wherein each of the plurality of wind turbine clusters are connected, by their respective connection stations, to an inter-cluster power network, by a respective one of a plurality of cluster transformers and a respective one of a plurality of second switchgear devices,
- a control system operatively connected to the second switchgear devices of the plurality of wind turbine clusters, and wherein the control system is configured to at least:
- identify the existence of a no-generation condition affecting at least one of the plurality of wind turbine clusters;
- control the switch status of the second switchgear devices, based on the identification, to control the connection status of each of the plurality of wind turbine clusters to the inter-cluster power network so as to reduce no load losses of the wind turbine clusters.
A method of operating a wind power plant, the power plant comprising a plurality of wind turbine clusters, wherein each wind turbine cluster includes a plurality of wind turbine generators connected to a connection station by an intra-cluster power network, each wind turbine generator being connected to the connection station by a respective one of a plurality of first switchgear devices of the connection station;
- and wherein each of the plurality of wind turbine clusters are connected, by their respective connection stations, to an inter-cluster power network, by a respective one of a plurality of cluster transformers and a respective one of a plurality of second switchgear devices, wherein the method comprises:
- identifying the existence of a no-generation condition affecting at least one of the plurality of wind turbine clusters;
- and
- controlling the switch status of the second switchgear devices, based on the identification, to control the connection status of each of the plurality of wind turbine clusters to the inter-cluster power network so as to reduce no load losses of the wind turbine clusters.
