摘要： A wind turbine (10) having a hub (14) with electrical power therein and at least one blade (20) attached to the hub, the blade (20) having a blade root (21), a blade tip (26) and a down-wire (30) for the conduction of lightning current to the ground. The wind turbine (10) further having a blade electrical system (99) that takes electrical power from the hub (14) and transmits electrical power into the blade (20) to at least one area located between the blade root (21) and the blade tip (26), the blade electrical system (99) comprising:
- a power-transfer unit (100) comprising a power-driver unit (110), a power-conditioner unit (130) and a dielectric (120) separating the power-driver unit (110) and the power-conditioner unit (130), the power-driver unit (110) receiving electrical power from the hub (14) and transmitting the electrical power, through the dielectric (120) to the power-conditioner unit (130),
- an electrical-power bus (200), electrically attached to the power-conditioner unit (130) and extending into the blade (20), and
- at least one powered unit (300) electrically connected to, and being electrically powered by, the electrical-power bus (200).-

摘要： A wind turbine blade (10) has a leading edge (14) and a trailing edge (15), a suction-side skin (11) joining at the leading edge (14) and trailing edge (15) with a pressure-side skin (12) to form a hollow blade structure, and a pressure measuring unit (99). The pressure measuring unit comprises a first connection tube (161) and a first sensing port (151), the first sensing port (151) fixedly attached to one of the suction-side skin (11) and the pressure-side skin (12), a second connection tube (165) and a second sensing port (155), the second sensing port (155) fixedly attached to one of the suction-side skin (11) and the pressure-side skin (12), and a pressure-sensing unit (100) receiving the first connection tube (161) at a first inlet port (113) and receiving the second connection tube (165) at a second inlet port (123). The pressure-sensing unit (100) has a first resistive unit (170) in fluid communication with the first inlet port (113), and a second resistive unit (174) in fluid communication with the second inlet port (123), the first resistive unit (170) and the second resistive unit (174) also in fluid communication with ambient air.
Further, the pressure-sensing unit (100) has a differential pressure sensor (130) producing a differential-pressure signal indicative of the pressure differential across the first inlet port (113) and the second inlet port (123). (Figure 2)-
