摘要

Modbus廣泛應用於工業界中，由於風機上具有多種電子裝置需要資料傳輸，Modbus具有易於實作且應用簡單，是可應用於風機監控的通訊協定之一。本研究根據Modbus協定，將其應用於風機資料傳輸，根據IEC 61400-25-2所規範的風機資料模型，採用現存的風機資料來模擬實體風機，把風機資料傳入伺服端的Modbus中來取代，伺服端的應用程式會將其載入並放入至的資料表(Data Table)中，客戶端會根據Modbus的通訊協定所定義的服務向伺服端索取對應的風機資料，本研究採用Visual Studio 開發平台以C#程式語言開發實作出兩種Modbus RTU與Modbus TCP/IP兩種通訊方式來傳輸風機資料。Modbus RTU 使用於未提供網路支援的設備，Modbus TCP/IP使用於有網路支援的設備。本研究實作出以Modbus監控風機的模擬軟體，可以更進一步與相關硬體結合開發成真正的風機監控系統。

Modbus protocol is widely used in industry and easily applied. As wind turbine contains lots of electrical devices which require data transmission and control, The Modbus is one of the protocols which can be applied in wind turbines. In this study, the Modbus protocol is applied to the wind turbine based on the information model defined by IEC61400-25 to transfer the information among the devices of a wind turbine. A Modbus server was simulated to store the information of wind turbine based on IEC61400-25. The server loads existed wind turbine data and stores it into Data Table of Modbus. The Modbus client is designed to ask for wind turbine data based on the service defined in Modbus protocol. The Visual Studio integrated development environment is the platform used with C# programming language to implement RTU and TCP/IP communication methods defined by Modbus protocol. The RTU method is used for the devices which doesn’t have the internet capability. The TCP/IP method is used for the devices with internet capability. A Modbus simulator is established in this study. It can be realized as a wind turbine communication and control system when combined with the corresponding hardware.
