在風(fēng)力發(fā)電中,變流器之間,變流器和風(fēng)機塔之間的數(shù)據(jù)交換都涉及到通信。無錫風(fēng)力風(fēng)機制造有限公司傳動單元的控制需要與整個風(fēng)場的通訊網(wǎng)絡(luò)相連,就需要大范圍,高速,可靠的通訊,所以DP在其中就承擔(dān)了至關(guān)重要的角色。但是在實際情況中,存在一個問題,控制變流器的控制器只能提供CAN通信的接口,和Profibus通信網(wǎng)絡(luò)相連遇到了兩種總線協(xié)議標(biāo)準(zhǔn)共存的問題。(圖/文http://www.lcxyljtrmyy.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.
