Problems solved by technology

[0005] In the wind power control system, not only the main control controller, the pitch controller and the variable current controller need to support Ethernet devices, but also put forward special requirements for the hardware specifications of the wind power control system; and it is necessary to set up routers and other Ethernet devices in the wind power control system. Network equipment can enable the main control controller, pitch controller and variable flow controller to communicate through Ethernet, which increases the cost of the wind power control system and is not convenient for the expansion and transformation of the communication network of the wind power control system

Embodiment 1

[0054] In order to facilitate understanding of this embodiment, a wind power control system disclosed in Embodiment 1 of the present invention is first introduced in detail.

[0055] see figure 1 , this embodiment provides a wind power control system, including: a main control controller 100, a pitch controller 102, a variable current controller 104 and an electric slip ring 106;

[0056] The pitch controller 102 is connected to the electric slip ring 106 through the CAN bus; the main control controller 100 and the inverter controller 104 are respectively connected to the electric slip ring 106 through the CAN bus; the main control controller 100 is also connected to the inverter through the CAN bus The controller 104 is connected;

[0057] The main control controller 100, the pitch controller 102 and the variable flow controller 104 perform data interaction through the CAN bus.

[0058] Specifically, the functions of the main control controller 100, the pitch controller 102...

Embodiment 2

[0081] see Figure 4, in order to realize the switching between the wired communication line (CAN bus) and the wireless redundant communication line in the wind power control system when the CAN bus fails, this embodiment provides a wind power control method using the wind power control system given in the above-mentioned embodiment 1 , including the following steps:

[0082] Step 300, the pitch controller judges whether the CAN bus communication is normal, if yes, execute step 302, otherwise execute step 304.

[0083] Specifically, step 300 specifically includes the following steps (1) to (3):

[0084] (1) The pitch controller judges whether the communication detection information sent by the main control controller and the variable flow controller is received, if yes, execute step 2, if not, execute step 3;

[0085] (2) The pitch controller feeds back the communication normal information corresponding to the communication detection information to the main control controlle...

Embodiment 3

[0096] see Figure 5 , in order to realize the switching between the wired communication line (CAN bus) and the wireless redundant communication line in the wind power control system when the CAN bus fails, this embodiment provides a wind power control method using the wind power control system given in the above-mentioned embodiment 1 , including the following steps:

[0097] Step 400, the main control controller sends communication detection information to the pitch controller through the CAN bus, so that the pitch controller judges whether the CAN bus communication is normal according to the received communication detection information.

[0098] Step 402 , the main control controller judges whether the communication normal information fed back by the pitch controller according to the received communication detection information is received within a preset time period, if yes, execute step 404 , if not, execute step 406 .

[0099] Step 404, the main control controller perfo...

Abstract

The invention provides a wind power control system and a wind power control method. The wind power control system comprises a master control controller, a variable-pitch controller, a variable-flow controller and an electric slip ring, wherein the variable-pitch controller is connected with the electric slip ring through a CAN bus; the master control controller and the variable-flow controller are respectively connected with the electric slip ring through the CAN bus; the master control controller is further connected with the variable-flow controller through the CAN bus; and the master control controller, the variable-pitch controller and the variable-flow controller mutually perform data interaction through the CAN bus. According to the wind power control system and the wind power control method provided by the invention, the control system is low in cost, the communication reliability is high, and the communication network expansibility is good.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a wind power control system and a wind power control method. Background technique [0002] At present, wind energy, as a clean and renewable energy, has attracted more and more attention from all countries in the world and has a huge reserve. Hundreds of wind power equipment are installed on the vast land of our country to convert wind energy into electrical energy, so as to make rational use of wind energy. In order to control the wind power equipment and grasp the conversion of electric energy in real time, a wind power control system will be set up to control the wind power equipment. [0003] In related technologies, the wind power control system mainly includes a main control controller, a pitch controller, and a variable flow controller, wherein the main control controller is connected to the variable flow controller and the pitch controller respectively, so that...
