元宝山二期工程60万千瓦机组于1985年3月受电进入试运阶段,在1985年11月13日并网发电。经过多次启停,逐步完善,最后于12月28日胜利移交生产。在机组试运全过程中,我们借助于微型电子计算,运用网络技术中的关键路径法软件对施工进度进行控制和调整,取得了一些经验,现简介如下: The 600,000-kilowatt unit of the second phase of the Yuanbaoshan project was put into trial operation in March 1985 and was connected to the grid for power generation on November 13, 1985. After several start-stops, it gradually improved, and was finally handed over to the production on December 28th. During the entire trial run of the unit, we used micro-electronic calculations to use the critical path method software in the network technology to control and adjust the construction schedule and gained some experience.
