Research on online remote monitoring of steam turbine power oscillation

Turbo-Generator's active power swing might lead to the low oscillation of Power Grid, which affected the safe and stable operation of units and power gird. Analyzing causes of turbine governing system swing, we found that abnormal characteristic of steam flow and jam fault of governing valve could be known by running parameters from online remote monitoring system. So we set up the online remote monitoring system of steam turbine power oscillation, which could analyse and find accident potential ahead of time.
