摘要(Abstract)：

汽包水位是表征锅炉安全运行的重要参数,由于配置、安装、运行及维护不当的原因,导致汽包水位测量系统存在测量值与实际值不符的情况,不同表计间显示偏差大,保护信号取样不合理现象一直存在,是机组安全稳定运行的隐患。对浙江省火电厂汽包水位测量、水位保护投入状况进行深入现场调查,总结和分析了问题产生的原因,探讨并提出了消除这些问题的技术改进措施。
Drum water level is an important parameter for safe operation of boiler.Because of improper configuration,installation,operation and maintenance,the differences between the observed value and the actual value are often found in drum water level measurement systems.There are always large deviations between different meters and unreasonable protection signal sampling.Those become hidden trouble for safe and stable operation of units.This paper summarizes and analyzes the causes for the existing problems based on the on-site investigation of drum water level measurement,water level protection operation in themal power plants in Zhejiang province,and presents the technical improvement measures to eliminate the problems.
