标题(英语)

Power converter for connecting a variable output generator to a supply network


摘要(英语)

A power converter to interface a generator 4 that provides variable voltage at variable frequency to a supply network operating at nominally fixed voltage and nominally fixed frequency includes features that allow the power converter to remain connected to the supply network and retain control during supply network fault and transient conditions. The power converter includes a generator bridge 10 electrically connected to the stator of the generator 4 and a network bridge 14. A dc link 12 is connected between the generator bridge 10 and the network bridge 14. A filter 16 having network terminals is connected between the network bridge 14 and the supply network. A first controller 18 is provided for controlling the operation of the semiconductor power switching devices of the generator bridge 14. Similarly, a second controller 46 is provided for controlling the operation of the semiconductor power switching devices of the network bridge 14. The first controller 18 uses a dc link voltage demand signal VDC GEN* indicative of a desired de link voltage to control the semiconductor power switching devices of the network bridge 10 to achieve the desired level of dc link voltage that corresponds to the de link voltage demand signal VDC_GEN*. The second controller 46 uses a power demand signal P* indicative of the level of power to be transferred from the dc link to the supply network through the network bridge 14, and a voltage demand signal VTURB* indicative of the voltage to be achieved at the network terminals of the filter 16 to control the semiconductor power switching devices of the network bridge 14 to achieve the desired levels of power and voltage that correspond to the power and voltage demand signals P* and VTURB*.
