||This thesis designs and implements a human-machine interface that can monitor the excited synchronous wind power system by Universal Asynchronous Receiver/ Transmitter(UART). The human-machine interface was developed by programming language of Visual C#. As to the communication parts, the serial port is RS232 and the object of communication is Microcontroller Unit (MCU) F28069 which is the control core of the wind power system. In order to improve the reliability of data, we also design programming package to communicate efficiently.|
There are six pages of table and an operational area in the main form of this human-machine interface, The six pages of table are operating instructions, status confirmation, parameter setting, numeric monitoring, graphical monitoring and data analysis. The status confirmation confirms whether the wind power system is ready to start or not; the parameter setting sets PID parameters of control strategies in the wind power systems; the numeric monitoring and the graphical monitoring observe the information of grid network, excited generator, servo motor and battery. The front one is represented by numeric, and the latter one is represented by graphs. The operational area is able to control excited generator to connect to the grid network and the power factor correction. As the results, the experiment demonstrates that this study can apply this human-machine interface to the excited synchronous wind power system.
