摘要
介绍了智能水电厂概念的提出对水电厂计算机监控系统现地控制单元(LCU)的影响,从LCU的结构模式、智能可编程逻辑控制器(PLC)、LCU的安全稳定3个方面,总结了目前水电厂LCU的现状和不足,并着重探讨了未来智能水电厂LCU的发展趋势。
The new concept of intelligent hydropower plant and its influence on local control unit（LCU） in the computer monitoring and control system of hydropower plants is introduced.The status and problems of LCU in existing hydropower plants are summarized from three aspects such as configuration mode,intelligent programmable logic controller（iPLC）,and security and stability.And the development trends of LCU in the future intelligent hydropower plant are discussed emphatically.
