回顾党的十一届三中全会召开二十年来,云南电网调度自动化事业的发展历程,令人高兴和振奋。 70年代末,云南电网调度自动化设备使用的远动设备功能比较简单,使用的是点对点同步时针式的SF—58型电磁式远动装置和WYZ—Ⅲ型、SZT型晶体管无触点式远动装置。这些远动设备容量小,可靠性低;用继电器或晶体管分离元件组成的逻辑电路,体积庞大;显示表头少,不能产生报表和存储历史数据。80年代,由于计算机技术的应
Recalling that the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China was convened for two decades, the development course of the Yunnan Grid Dispatching Automation Business was pleasing and inspiring. At the end of the 1970s, the remote-control equipment used in dispatching automation equipment in Yunnan Power Grid was relatively simple. It used a point-to-point synchronous hour-type SF-58 electromagnetic telecontrol device and WYZ-III and SZT transistor non-contact remote control. Device. These remote devices have small capacity and low reliability. The logic circuit composed of relay or transistor separation elements is bulky; there are few display headers, and reports and historical data cannot be generated. In the 80s, due to the
