Embodiment 1

[0037] like figure 1 As shown, the communication control and protection device is arranged at the front end of the communication equipment of the wind turbine, and includes: a short circuit protection module, an equipment interface connected to the communication equipment, a power interface, a lightning protection module and a signal light.

[0038] Wherein, the short-circuit protection module includes an equipment short-circuit protection module and a line short-circuit protection module, the equipment short-circuit protection module performs short-circuit protection on the communication equipment, and the line short-circuit protection module short-circuits the communication lines of the communication equipment Protect;

[0039] The lightning protection module includes a lightning protection module for outgoing lines and a lightning protection module for incoming lines, which are used for lightning protection of the communication equipment;

[0040] The signal light gives a ...

Embodiment 2

[0050] like Figure 5 As shown, it is a flow chart of a communication control and protection method applied to a wind turbine provided by the present invention. Using the communication control and protection device described above, the method may include the following steps:

[0051] Step S101: In response to a short-circuit fault in the communication equipment or lines of the wind turbine, the short-circuit protection module monitors the pulse signal.

[0052] Step S102: Determine whether the pulse signal is lost after the pulse signal continues for a set period of time; if so, step S103 is performed.

[0053] Step S103: The pulse relay operates, and the normally closed terminal is switched to the normally open terminal, and the signal side is temporarily disconnected from the detection point, so that the steady state triggers the signal terminal, the first normally open terminal, the second normally open terminal, the first common terminal, and the normally closed terminal. ...

Description

technical field [0001] The invention relates to the technical field of control equipment, in particular to a communication control protection device and method applied to a wind turbine. Background technique [0002] The communication equipment of wind farms built in the early days is mostly connected in series with copper cables with simple structure and low cost. This connection method has a great influence on the stable operation of the communication network of wind farms. For example, when multiple communication equipments connected in series Once any one of the communication devices sends a short circuit, the entire communication network will be interrupted. Especially in thunderstorm weather, copper cables are easily struck by lightning, resulting in damage to communication equipment and interruption of communication. Since the wind farm monitoring system cannot monitor the status of the units in real time, it is difficult to guarantee the healthy operation of the farm...
