In a wind farm, each wind turbine is distributed in the wind farm with a certain distance between them, and the wind resources and terrain environment where each wind turbine is located have certain similarities and differences. At present, the units in wind farms are affected by their own mechanical characteristics, and the control of most units is independent. In the control process of the unit, the controller of each unit needs to obtain the external environment information such as gust, turbulence, temperature, etc. corresponding to the unit, and then determine the corresponding control strategy of the unit. However, when the controller of the unit cannot obtain certain external environmental information such as temperature or the obtained external environmental information is wrong, such as the failure of the wind speed and direction instrument, the control strategy of the unit will be inaccurate, which may cause accidents of the unit. Shutdown, severe cases may face unit accidents.

具体实施方式Detailed ways
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例对本发明进行进一步详细说明。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
风电机组的控制系统实施例：Examples of control systems for wind turbines:
本实施例提供了一种风电机组的控制系统，该控制系统通过将各个风电机组对应的风电机组控制器互联起来，以实现各风电机组之间的信息共享。当风电机组的某一环境信息无法获取时，则及时获取其他机组的对应的环境信息，来确定本机组的控制策略，大大降低了各个风电机组独立控制时的故障率，提高了机组的有效运行时间，避免了现有风电机组因外部因素导致机组策略停机所带来的发电量的损失，对电网的冲击，机组损害等不良影响。This embodiment provides a control system for wind turbines. The control system realizes information sharing among wind turbines by interconnecting the controllers of wind turbines corresponding to each wind turbine. When a certain environmental information of the wind turbine unit cannot be obtained, the corresponding environmental information of other units can be obtained in time to determine the control strategy of the unit, which greatly reduces the failure rate of each wind turbine unit when it is independently controlled, and improves the effective operation of the unit Time, avoiding the loss of power generation caused by the strategic shutdown of the existing wind turbines due to external factors, the impact on the power grid, and the damage to the unit and other adverse effects.
如图1所示，该风电机组的控制系统包括一个中央控制器以及与各风电机组对应的风电机组控制器，中央控制器和各个风电机组控制器通过POWERLINK光纤环网进行互联，可以实现各风电机组控制器之间的信息交互，以实现数据共享。As shown in Figure 1, the wind turbine control system includes a central controller and wind turbine controllers corresponding to each wind turbine. The central controller and each wind turbine controller are interconnected through the POWERLINK optical fiber ring network, which can realize the Information exchange between unit controllers to achieve data sharing.
如图2所示，对各风电机组对应的风电机组控制器进行POWERLINK接口扩展，要求至少要扩展两个及以上的POWERLINK口和一个网口，每个风电机组控制器还配备两组光纤模块和POWERLINK模块，这样各风电机组控制器均连接有两组光纤模块和POWERLINK模块。中央控制器具备两个POWERLINK口，并配备两组光纤模块和POWERLINK模块，这样中央控制器也连接有两组光纤模块和POWERLINK模块。在图2中，中央控制器和风电机组控制器连接的光纤模块通过光纤连接(虚线)，中央控制器和风电机组控制器连接的POWERLINK模块通过POWERLINK连接(实线)。在本实施例中，风电机组控制器的型号为X20CP3586，X20CP3586可扩展成3个POWERLINK接口；中央控制器的型号为APC910，其本身具备两个POWERLINK口。As shown in Figure 2, to expand the POWERLINK interface of the wind turbine controller corresponding to each wind turbine, it is required to expand at least two or more POWERLINK ports and one network port. Each wind turbine controller is also equipped with two sets of optical fiber modules and POWERLINK module, so that each wind turbine controller is connected with two groups of optical fiber modules and POWERLINK modules. The central controller has two POWERLINK ports, and is equipped with two sets of optical fiber modules and POWERLINK modules, so that the central controller is also connected with two sets of optical fiber modules and POWERLINK modules. In Fig. 2, the optical fiber module connected between the central controller and the wind turbine controller is connected through optical fiber (dotted line), and the POWERLINK module connected between the central controller and the wind turbine controller is connected through POWERLINK (solid line). In this embodiment, the model of the wind turbine controller is X20CP3586, and the X20CP3586 can be expanded into three POWERLINK ports; the model of the central controller is APC910, which itself has two POWERLINK ports.
各风电机组控制器连接的一个POWERLINK模块通信连接前面一台风电机组控制器或者中央控制器连接的其中一个POWERLINK模块，另外一个POWERLINK模块通信连接后面一台风电机组控制器或者中央控制器连接的其中一个POWERLINK模块，从而构成了POWERLINK环网。各风电机组控制器连接的一个光纤模块通信连接前面一台风电机组控制器或者中央控制器连接的其中一个光纤模块，另外一个光纤模块通信连接后面一台风电机组控制器或者中央控制器连接的其中一个光纤模块，从而构成了光纤环网。如图1所示，虚线表示的是POWERLINK环网，实线表示的是光纤环网。One POWERLINK module connected to each wind turbine controller communicates with one of the POWERLINK modules connected to the front wind turbine controller or central controller, and the other POWERLINK module communicates with one of the rear wind turbine controllers or central controller. A POWERLINK module constitutes a POWERLINK ring network. One fiber optic module connected to each wind turbine controller communicates with one of the fiber optic modules connected to the front wind turbine controller or central controller, and the other optical fiber module communicates with one of the rear wind turbine controllers or central controller. An optical fiber module constitutes an optical fiber ring network. As shown in Figure 1, the dotted line represents the POWERLINK ring network, and the solid line represents the optical fiber ring network.
POWERLINK环网和光纤环网一起，构成了POWERLINK光纤环网，该POWERLINK光纤环网是一个相对独立的系统。需要说明的是，通过在POWERLINK光纤环网中设置中央控制器，可以使后台获取各个风电机组中对应风电机组的控制信息，也便于后期功能的扩展。例如，POWERLINK光纤环网测试通过后，可以将现有风场环网挂载的用于电网调度的AGC(自动发电控制)、AVC(自动电压控制)装置进行分离，使中央控制器集成AGC、AVC功能，这时POWERLINK光纤环网能够满足风电机组对电网频率变化进行支撑的快速响应需求，以及实现风电机组间的数据快速共享。因此，作为其他的实施方式，在POWERLINK光纤环网也可以不设置该中央控制器。The POWERLINK ring network and the optical fiber ring network together constitute the POWERLINK optical fiber ring network, and the POWERLINK optical fiber ring network is a relatively independent system. It should be noted that by setting the central controller in the POWERLINK optical fiber ring network, the background can obtain the control information of the corresponding wind turbines in each wind turbine, and it is also convenient for later function expansion. For example, after the POWERLINK optical fiber ring network test is passed, the AGC (automatic generation control) and AVC (automatic voltage control) devices mounted on the existing wind farm ring network for grid dispatching can be separated, so that the central controller integrates AGC, AVC function, at this time, the POWERLINK optical fiber ring network can meet the fast response requirements of wind turbines to support grid frequency changes, and realize fast data sharing among wind turbines. Therefore, as another embodiment, the central controller may not be provided in the POWERLINK optical fiber ring network.
另外，光纤环网属于现有风电场中已经存在的网络，POWERLINK光纤环网是在风电场光纤环网架构的基础上建立的，是一个可靠性高、响应速度快的网络，以实现风电机组之间的数据共享。作为其他的实施方式，中央控制器和各风电机组控制器之间也可以只构建POWERLINK环网。当然，在保证各风电机组之间的信息交互快速有效的前提下，即获取其他机组的环境信息的响应时间低于风电机组控制的循环周期，该POWERLINK环网也可以替换为现有技术中的其他类型的环网。In addition, the optical fiber ring network belongs to the network that already exists in the existing wind farm. The POWERLINK optical fiber ring network is established on the basis of the optical fiber ring network architecture of the wind farm. It is a network with high reliability and fast response speed to realize wind turbine data sharing among them. As another implementation manner, only a POWERLINK ring network may be constructed between the central controller and each wind turbine controller. Of course, under the premise of ensuring fast and effective information exchange between wind turbines, that is, the response time for obtaining environmental information of other wind turbines is lower than the cycle period of wind turbine control, the POWERLINK ring network can also be replaced by the existing technology Other types of rings.
通过POWERLINK光纤环网，上述的风电机组的控制系统可以实现一种风电机组的控制方法，步骤如下：Through the POWERLINK optical fiber ring network, the above wind turbine control system can implement a wind turbine control method, the steps are as follows:
(1)各风电机组控制器实时获取其对应的风电机组自身的环境信息。(1) The controllers of each wind turbine obtain the environmental information of its corresponding wind turbine itself in real time.
其中，这里的环境信息为影响风电机组故障的信息，包括阵风、湍流、机舱外温度、空气密度和结冰数据，阵风和湍流会导致机组振动过大停机，温度、空气密度、结冰等传感器故障会造成机组停机。Among them, the environmental information here is the information that affects the fault of the wind turbine, including gust, turbulence, temperature outside the cabin, air density and icing data. Gust and turbulence will cause the unit to vibrate too much and stop. A failure will cause the unit to shut down.
(2)当风电机组控制器无法获取其对应的风电机组自身的某一环境信息时，则获取与该风电机组控制器互联的其他风电机组控制器的风电机组对应的环境信息。(2) When the wind turbine controller cannot obtain certain environmental information of its corresponding wind turbine itself, then obtain the environmental information corresponding to the wind turbines of other wind turbine controllers interconnected with the wind turbine controller.
其中，在风电场中，一些风电机组的环境信息存在相同或者相近的情况。这样，当某台风电机组的某些环境信息无法获取时，例如，某风电机组的温度传感器故障，导致该风电机组对应的风电机组控制器无法获取到该风电机组对应的温度，这时风电机组控制器可以通过POWERLINK光纤环网获取与本风电机组的环境信息相同或者相似的其他风电机组的环境信息，例如可以获取与该风电机组邻近的其他风电机组对应的环境信息，并将获取的环境信息当做自身的环境信息进行使用。Among them, in the wind farm, the environmental information of some wind turbines is the same or similar. In this way, when some environmental information of a certain wind turbine cannot be obtained, for example, the temperature sensor of a certain wind turbine fails, so that the corresponding wind turbine controller of the wind turbine cannot obtain the corresponding temperature of the wind turbine, then the wind turbine The controller can obtain the environmental information of other wind turbines that is the same or similar to the environmental information of the wind turbine through the POWERLINK optical fiber ring network. Use it as your own environmental information.
(3)风电机组控制器根据获取的其他风电机组控制器的风电机组对应的环境信息，确定自身对应风电机组的控制策略，并根据确定的控制策略对自身对应风电机组进行控制。(3) The wind turbine controller determines the control strategy of its own corresponding wind turbine according to the obtained environmental information corresponding to the wind turbines of other wind turbine controllers, and controls its corresponding wind turbine according to the determined control strategy.
其中，风电机组控制器利用获取的与自身风电机组的环境信息相同或者相似的其他风电机组对应的环境信息，制定自身风电机组的控制策略，这样就避免了某一环境信息缺失导致风电机组的控制策略不准确的现象，避免了机组停机或故障，有效保证了风电机组正常运行。由于各个风电机组控制器根据环境信息制定自身对应风电机组的控制策略的过程属于现有技术，此处不再赘述。Among them, the wind turbine controller uses the acquired environmental information corresponding to other wind turbines that is the same as or similar to the environmental information of its own wind turbine to formulate its own control strategy for the wind turbine, thus avoiding the control of the wind turbine caused by the lack of certain environmental information. The inaccurate strategy avoids the downtime or failure of the unit, and effectively ensures the normal operation of the wind turbine. Since the process of each wind turbine controller formulating its own control strategy corresponding to the wind turbine according to the environmental information belongs to the prior art, it will not be described here.
