HT-7电源控制系统为三级分级分布式计算机系统,其中第一级由LX386、DEC486组成,第二级由两台8098组成,第三级由四台8031单片机组成.此外由 SIMATIC S 5-135 U可编程控制器完成控制系统的开关时序量控制、状态巡检及系统保护.系统控制对象为20MW的三相全控桥、保护旁通桥以及电源回路几百个开关量、模拟量.HT-7电源系统设计中的重要问题是消除可能产生的各种干扰以确保系统安全可靠运行.
HT-7 power control system for the three grading distributed computer system, which consists of the first level by the LX386, DEC486 composition, the second stage consists of two 8098, the third stage consists of four 8031 SCM.In addition by the SIMATIC S 5- 135 U programmable logic controller to complete the control of the switch timing control, state inspection and system protection system control object for the 20MW three-phase full control bridge, bypass and the protection of the power circuit hundreds of switches, analog. An important issue in the design of HT-7 power system is to eliminate all kinds of interference that may occur to ensure the safe and reliable operation of the system.
