摘要
电排站是防洪排涝、灌溉、调水的水利设施,对水利的调度起着重要性作用.介绍了国内外电排站当前控制系统的方式和特点,将其控制方式分为常规控制、智能仪表、PLC现场总线及计算机控制4种类型,对每种类型的控制结构和组成进行了闸述.最后,结合控制系统的发展变化过程和当前技术的发展趋势,指出网络化的计算机集成控制系统是技术的发展趋势,最终目的是实现"无人值班,少人值守"的目标.
Pump stations are key facilities of flood control and drainage, irrigation, and water conservancy, thus playing an important role in water regulation. This paper first introduces the control methods and characteristics of pump stations all over the world. The control methods are categorized into four different kinds, namely normal control, intelligent instruments, PLC field bus and computer control,with the struc- ture of each kind being discussed in detail. Finally, based on the evolution process and current trend of control system, it points out that the technological trend is heading for the integrated computer network control system,with the ultimate aim of being "unmanned and unattended".
