DC transmission is the important in the strategic planning of "power transmission from west to east". It's also one of the main develop directions of pwower transmission technology, in HVDC, The water scaling of inside cooling water in converter stations is the main factor that influences the stable operation of power transmission system. In order to real-time monitor the water in converter stations, without manpower intervention, It can real-time monitors the PH value, aluminun ion and electric conductivity of inside cooling water, through comprehensive analysis it can provides the basis to setermine the optimal operating conditions for converter stations, and have the function of early warning for fault. The result of experimentation indicates that the function is completely and the performance is stablity.%直流输电是我国“西电东送”战略规划的重要环节,也是输电技术的主要发展方向之一.直流输电中换流站内冷水结垢是影响输电系统稳定运行的主要因素.为了实时监测内冷水的水质情况,文章研制了一套换流站内冷水在线监测系统,能够在无人工干预的情况下,实时监测内冷水的PH值、铝离子和电导率等指标,综合分析后可以为换流站确定最佳运行条件提供依据,并起到故障预警的作用.现场试验测试表明,该套系统功能齐全、性能稳定.
