Validation of sliding stator feet for Hissmofors G6 andG7 (engelsk)
Abstract [en]

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage.

 

The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation.

 

The results show that there are several indications that the function of the sliding stator feet is not satisfactory. However, some results indicate well functioning stator feet.. The recommendation to Jämtkraft will therefore be to further investigated its performance by conducting a new roundness measurement and make new eccentricity calculations accordingly.
