Windows based Data Acquisition and Monitoring System for Micro-turbine Yao Guochun1** Zhang Weigang1 Yang Weilie2 Zhu Xiaolin2 1 Dept.of E.E.,Tsinghua University, Beijing,100084; 2 Beijing Chargebroad Electric Vehicle Co.Ltd Beijing 100176） Abstract:. Micro-turbine, a micro gas turbine (MGT) electricity-generating system with low emission, can be widely used in the fields, such as distributed power station, combined cooled heated and power(CCHP), and hybrid electric vehicle. In order to study the performance of micro-turbine, the experimental system composed of micro-turbine, oil exhaust meter, power battery pack and load is designed. According to Modbus protocol, through the standard RS-232 serial port for customer maintenance on digital power controller(DPC) unit in the micro-turbine, in charge of controlling output electric power, Windows-based monitoring software with multi-thread serial communications port class by using Visual C++ language, is programmed to monitor and control the performance status of micro-turbine and record the acquisition data such as power, oil cost and output voltage on real time. It shows reliable communication and robust control in practice use.
