Wind turbine control system is complex, the main control system and the executive system need to work closely together to realize the efficient transformation of wind energy to electricity, one of the important links is the inverter system, the system's stable operation, is the key to achieve constant frequency power generation. With Anybus embedded and Anybus gateway solutions, the wind power converter can be seamlessly connected to the main control system without any communication problems.

The wind power converter is mainly used in the wind power generation system with the generator to realize that the amplitude, frequency and phase of the output voltage on the stator side of the generator are the same as those of the power grid, so as to realize variable speed and constant frequency power generation, to obtain the optimal power generation efficiency and quality, and to enhance the utilization rate of wind energy. In view of this, the internal main controller of the converter needs to communicate with the main controller of the generating unit to transmit data to the main controller of the generating unit in a fast, stable and safe manner, and to set the control commands of the wind generating unit to the converter in time.

“Our inverters are mostly CAN and CANopen interfaces, when the master control also adopts CAN/CANopen for communication, we can communicate with the master control normally, but some of the master control mostly adopts Siemens PLC, which uses PROFIBUS DP or PROFINET for communication, which poses a difficult problem for us. ” the customer mentioned. “If we develop different protocols one by one with dedicated chips or protocol stacks, it will take a long period of time, and we have to pay attention to the risk of research and development, testing and certification issues, and some of the old models which are used stably in the field, we don't want to change the software and hardware of the converter itself easily. ”

After much comparison, the converter manufacturer chose Anybus solution. With a rich product portfolio, from Anybus embedded modules that are plug-and-play and help the customer's converter to extend the network interface, to gateway products that can be independently installed outside the converter, Anybus provides the customer with sufficient flexibility to realize seamless communication with the main control PLC system. We expect the system to run stably and reliably in the harsh environments where wind turbines are often installed far from the city, in the field, or in the mountains,“ said the customer, ”because if there is any problem with the operation, it will lead to failure or shutdown, which will result in a huge loss of money. The high performance and stability of Anybus products in harsh environments and the excellent support services from the HMS team have relieved us of any worries. "
Anybus Gateway
Anybus Communicator gateway is a rail-mounted, external, independent protocol conversion product, which can help customers to convert the original Modbus interface of some models to PROFIBUS or PROFINET access master directly through graphical configuration without changing any of the customer's hardware or software.

Thousands of M40 modules and Anybus Communicator gateways have been deployed in wind turbine inverters with stable and reliable operation in the field. The consistent quality of the product has allowed the customer to continue to choose Anybus gateways as the communication solution for their transmission inverters, which are now available and continue to grow at a high rate.
