Application of Hydropower Unit On-line Monitoring System in Three Gorges Left Bank Hydropower Plant

摘要

Three Gorges Left Bank HydroPower Plant is installed with turbo-generating units with unit capacity of 700MW. Because of the wide range of head variation and complex operating condition, the operation stability of the units are extensively concerned. The operation management of Three Gorges Left Bank HydroPower Plant pays great attention to this issue and decided to conduct on-line monitoring and analysis of unit operation status for real-time acquisitioning operating characters and ensuring safe and steady running of units. By now, 4 units in the HydroPower Plant are installed with TN8000 unit status monitoring-analysis and trouble diagnosis systems developed and manufactured by Beijing Huake Tong'an Co., Ltd. Since putting into operation, TN8000 system has played an important role in acquisitioning unit operation characters and catching and analyzing accident. This paper describs in details the composition, features, functions and application of TN8000 unit status monitoring system used in Three Gorges Left Bank HydroPower Plant.
