The invention relates to a controller of a converter of a dual-fed
wind power generator, which is formed by connecting a touch display screen, a PLC module, a
data acquisition and control module and a
network interface module, wherein the touch display screen is connected with the PLC module, the PLC module is connected with one end of the
network interface module, the other end of the
network interface module is connected with a control and
pitch control system of a wind
turbine, the PLC module is further connected with the
data acquisition and control module, and the
data acquisition and control module is simultaneously connected with a rotor side
power module and a network side
power module. The controller adopts the
modular design and can realize the double closed-
loop control of a power outer loop and a current
inner loop through acquisition, analysis and treatment of various analog signals, digital quantity signals and rotation speed signals, and simultaneously realize the functions of centralized acquisition of data, fault prediction, diagnosis and the like, and has the characteristics of strong anti-interference ability, abundant network interfaces,
fast measurement speed, high control precision, friendly man-
machine interface and the like.
