Abstract

The invention provides a method and a device for debugging a variable-pitch system of a wind generating set. The device comprises a host computer, a main station device and a variable-pitch device, wherein the host computer is connected with the main station device through the Ethernet; the main station device is connected with the variable-pitch device through a CANopen bus; a user reads information of the variable-pitch system through the human-machine interface of the host computer and performs corresponding operation on the variable-pitch system; the program of the main station device is used for processing the state information of the variable-pitch system and the control command of the host computer; and the variable-pitch system is used for transmitting all state information to the main station device and receiving the control command transmitted by the main station device to perform actions such as pitch variation. The method and the device have the beneficial effects that due to the adoption of the technical scheme, the debugging device is small in size, and is easy and convenience to operate; the host computer is connected with the main station device through the Ethernet, so that safety and reliability are realized; and data are exchanged with variable-pitch device accurately and timely through a PDO (PHP Data Object) and an SDO (Service Data Object) of CANopen bus communication.

Description

technical field [0001] The invention belongs to the field of control and mediation, and in particular relates to a monitoring, inspection and control platform for a pitch-variable system of a wind power generating set. Background technique [0002] In the existing technology, the wind power generation system mainly includes three parts: main control, frequency conversion and pitch change. , In recent years, with the increase of stand-alone capacity and the continuous improvement of grid-connected requirements, variable-pitch and variable-speed wind turbines have gradually become the mainstream and development trend. [0003] The variable pitch variable speed wind turbine adopts the variable pitch control system to adjust the angle of the blades. Its main function is to adjust the windward angle of the fan blades under normal power generation conditions, thereby dynamically adjusting the input power and improving the utilization rate of wind energy. ; In the fault state, the...
