在风力发电中，变流器之间，变流器和风机塔之间的数据交换都涉及到通信。无锡风力风机制造有限公司传动单元的控制需要与整个风场的通讯网络相连，就需要大范围，高速，可靠的通讯，所以DP在其中就承担了至关重要的角色。但是在实际情况中，存在一个问题，控制变流器的控制器只能提供CAN通信的接口，和Profibus通信网络相连遇到了两种总线协议标准共存的问题。（图/文http://www.wxfengli.com/）

In wind power, converter, converter and fan tower data exchange between both relates to communication. The transmission unit control need and the wind field communication network connected, requires a large range, high speed, reliable communication, so the DP which assume a crucial role. But in practice, there exists a problem, control converter controller can only provide a CAN communication interface, and Profibus communication network connected across two bus protocol standard coexistence problem.
