丹江口加高工程升船机拖动控制系统设计研究

丹江口大坝加高工程是南水北调中线工程的重要部分，大坝加高后，枢纽过坝设施亦需改建。改建后垂直和斜面升船机的提升运载能力将达到300吨级，相应地拖动系统功率分别为1600和800kw，且控制系统功能要求更高。为此，对改建的两级升船机的拖动及控制系统设计进行了研究：根据升船机的特点和运行特性要求，并从技术先进、节约电能、安全可靠和维护方便等因素考虑，垂直及外面升船机主拖动系统均采用交流变频调速系统；两级升船机均各自采用两层分布式控制结构，其上再设监控管理级进行集中调度管理。另外，对检测系统、通航指挥及监视系统亦作出方案研究。综合研究成果表明：丹江口加高后升船机选择交流传动变频调速的方案是合适的。

Optimization of deformation monitoring networkfor high slope at TGP shiplocks

The deformation monitoring network of high slope at TGP shiplocks is a component of safety monitoring system for the whole project. Its optimization objective is to achieve a better, faster and more economical deformation monitoringnetWOrk, namely to properly handle the relationship among accuracy, speed and economy. Items of optindzation mainly include the levels Of network layout, diagram structure, and observation schemes. The plane monitoring netWork is divided intOthree levels, namely the simplest netWork, simple network and fun network. The reqUirement of accuracy for networks at every level is consistent. Observation should be freqUent for the simplest netWork, moderate for simple netWork, and less forfull network. The network shape and observation scheme at every level are optimized to achieve a better diagram structure sothat high accuracy monitoring data may be obtained in shorter time with smaller work quantity. The elevation monitoring network is divided into twO levels, namely vertical displacement monitoring network and check network. These optimized deformation monitoring networks achieving good results haVe played an important role in TGP d~c design and constructionguiding.
