电力系统静态模拟系统是一种十分重要的仿真实验设备，在电力类高校和研究机关中得到了普遍的应用。到目前为止，静模系统的监控手段大都比较落后、设备复杂、维护因难、使用不便，限制了这一技术的进一步发展和应用。本文在总结前人工作的基础上，设计出了以高性能工业控制机、PLC可编程逻控制器、NI多功能数据采集板为硬件核心，以虚拟仪器编程环境Lab-Windows为软件平台的静模计算机监控系统，解决了现有静模系统存在的种种问题，大大提高了静模系统的性能指标。%Power system static model is a important simulation test device. It has found widely use in the universities and research institutes that specialize in power system. But the monitoring and control of the model system so far highly lags behind that used in real power system and commonly has the defect of using more circuit elements, complex wiring,inconvenience in use,and difficulty for maintenance. To overcome these defects and improve the performance of rnthe static model system,a model system computer monitoring and control network is designed in this paper. The network uses industrial computer, programmable logical controller (PLCs),National Instruments multi-purpose data acquiring board as hardware foundation and the virtual instrument language Lab-Windows as software platform. The fundamental structure of hardware system and flow chart ofsoftware is presented. Application result of the system is rernported.
