Abstract: An electric power converter system with an electric power converter, e.g. an AC-DC converter, a DC-AC converter or both. The electric power converter is air cooled by a cooling system having a fluid flow system arranged to force air or liquid through a primary flow path of a heat exchanger. An internal air flow with a fan serves to force air in a loop through a secondary flow path of the heat exchanger and the electric power converter to cool the electric power converter. A controllable bypass inlet opening mechanism provides a controllable opening to allow an inlet of ambient air into the internal air flow, and a control system receives at least one input parameter and being arranged to control the controllable bypass inlet opening mechanism accordingly. A bypass outlet opening, such as having a controllable bypass outlet opening mechanism, is arranged to provide an opening to allow an outlet of air from the internal air flow. The control system is preferably arranged to control the controllable bypass inlet opening mechanism accordingly to at least a temperature sensor sensing a temperature in the internal air flow at a position upstream of the electric power converter. Further, the controllable bypass inlet opening mechanism may be controlled also in response to a sensed humidity in the internal air flow, and a measure of electric power generated by the electric generator.

Abstract: Aspects of the present invention relate to a rotor arrangement (42) for a wind turbine generator (24). The rotor arrangement (42) comprises a cylindrical ring structure (46) arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises: a plurality of ring-shaped permanent magnet packages (48) arranged coaxially around the rotational axis, a plurality of tie rods (55) extending axially through the plurality of permanent magnet packages (48) to join the plurality of permanent magnet packages (48) together; and one or more spacer components (64; 164) located between at least one axially adjacent pair of the plurality of permanent magnet packages (48) to space the respective pair of permanent magnet packages (48) apart, wherein the one or more spacer components (64; 164) are configured to act as an impeller as the rotor rotates, in use, thereby to cause air to flow in a radial direction, with respect to the rotational axis of the rotor arrangement (42), between the at least one axially adjacent pair of permanent magnet packages (48). The generator rotor arrangement uses a portion of the kinetic energy of the rotating rotor arrangement to generate a radial air flow that flows between and/or around the magnet packages to transfer heat away from the magnet packages, and thereby to provide a cooling function.

Abstract: An electric modular system for connection to a hybrid power plant. An enclosure (CNT), e.g. a standard size container houses: 1) a first electric converter system (CV1) connected to an electric output of a wind turbine and generates a first DC output, 2) a second electric converter system (CV2) arranged connected to an output of a photovoltaic source (PV) or a battery (BT) and generates a second DC output, 3) an output electric converter system (CV0) receiving the first and second DC outputs and generates an electric output e.g. for connection to an electric grid. A cooling system (CLS) with a flow duct to receives air from outside and provides a controllable amount of cooling to the electric converter systems accordingly, e.g. via controllable flow resistive elements. A cooling controller (CC) senses output loads (L1, L2, L0) of the electric converter systems (CV1, CV2, CV0) and controls the cooling system (CLS) to direct an amount of cooling to the electric converter systems (CV1, CV2, CV0) as a function of their electric output loads (L1, L2, L0). Especially, back-to-back mounted sets of cabinets with modules of the electric converter system, and each with a dedicated cooling unit allows effective use of cooling capacity according to the actual electric load situation.

Abstract: A wind turbine (10) includes a nacelle (14) with a longitudinal axis (LA) aligned with the flow of the incoming wind during operation. When so aligned, the nacelle defines a longitudinal direction (X). The wind turbine (10) includes one or more heat-generating components (22) and a modular cooler (24) operatively coupled to the one or more heat-generating components (22). The modular cooler (24) includes one or more cooling modules (30) with each including one or more cooling units (32). Each cooling unit (32) includes a heat exchanger (40) defining a cooling area (38), which defines a normal axis (NA) and a deflector plate (42) to divert the flow of the incoming wind by an angle less than 180º relative to the longitudinal direction (X). Each cooling unit (32) is oriented such that the normal axis (NA) is non-parallel to the longitudinal axis (LA). The modular cooler (24) is scalable in multiple dimensions to increase the cooling capacity of the cooler (24). A method of assembling the modular cooler (24) is also disclosed.
