满拉水电站位于西藏雅鲁藏布江支流年楚河上游， 海拔高度达４ ２００ ｍ 。计算机监控系统应充分考虑海拔高度的影响， 系统应简单可靠， 重要的部件具有足够的可靠性等。针对这一需求， 通过对三种方案的技术、经济比较， 最终选定采用以莫迪康紧凑型ＰＬＣ为基础构成的计算机监控系统。
Manla Hydropower Station is located in the upper reaches of the Nianchu River, a tributary of the Yarlung Zangbo River in Tibet at an altitude of 4 200 m. Computer monitoring system should take full account of the impact of altitude, the system should be simple and reliable, important components with sufficient reliability. In response to this demand, through the technical and economic comparison of the three solutions, a computer monitoring system based on Modicon Compact PLC was finally selected.
