Abstract: A control network (54) for a wind turbine system (2), the wind turbine system (2) comprising multiple rotor-nacelle assemblies (6) mounted on a support structure (4), the control network (54) comprising: a respective local network (48) associated with each rotor-nacelle assembly (6), each local network (48) comprising multiple nodes (50, 52); a central network (22) that is connected to each local network (48), the central network (22) comprising multiple nodes (24, 26); and a synchronisation device that synchronises data transmission throughout the control network (54).

Abstract: To safely operate a wind turbine, a control system may determine a current state of the wind turbine and identify whether the state is within an operational envelope. Based on measured sensor data, the control system may calculate the current state of the turbine in a multi-dimensional space where each axis of the multi-dimensional space correlates to one of the measured parameters. The boundary of the operational envelope may define a region of the multi-dimensional space where the wind turbine is behaving in a safe manner. A safety system may determine if the state determined by the control system is accurate. If so, the safety system determines whether the current state is within the operational envelope. If the state is outside the envelope, the wind turbine may switch to a safe state during which the turbine may be decoupled from the utility grid or the rotor is stopped.

Abstract translation: 为了安全地操作风力涡轮机，控制系统可以确定风力涡轮机的当前状态并且识别该状态是否在操作范围内。 基于测量的传感器数据，控制系统可以在多维空间中计算涡轮机的当前状态，其中多维空间的每个轴与所测量的参数之一相关。 操作包络的边界可以限定风力涡轮机以安全的方式行进的多维空间的区域。 安全系统可以确定由控制系统确定的状态是否准确。 如果是这样，安全系统确定当前状态是否在操作范围内。 如果状态在信封之外，则风力涡轮机可以切换到安全状态，在该状态期间，涡轮机可以与公用电网分离或转子停止。
