基于WINDOWS 的微型涡轮发电机组数据采集监控系统

微型涡轮机是一低排放微型燃气轮机系统，由其组成的微型涡轮发电机组可广泛应用于分布式电站、冷热电联产以及混合电动汽车等领域。为对涡轮机组进行性能试验研究，将涡轮发电机组与油耗仪、外接电池组和负载组成试验系统，通过微型涡轮机数字功率控制器—DPC(负责控制发电机功率)用户维护串口，在Modbus 协议基础上，采用VC++多线程串口类开发了基于Windows 监控程序，对涡轮机运行状态，功率，油耗，输出电压等参数进行实时监控，并记录实时数据。实际运行表明系统通讯可靠控制良好。

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.
