The main contents are as follows:①Under the analysis of present situation of the development of TPM and the equipment management of China\'s small and medium hydropower stations, it summarized problems of the small and medium hydropower station equipment management, finally pointed out the idea for solution.

By concretely analysis of typical reach and shoal, it opens out the common regulation of riverbed evolution in fluctuating backwater area of medium and small hydropower plant building on alluvial river in mountainous area.

Computation of backwater end for small hydropower station on mountainous river;

Generating technology of velocity-varying system used in small hydropower stations;

Application of FRP pipe in small hydropower station;

The SJ-100 integrated automation device is designed considering the characteristics of small hydropower plants,which integrates the functions of monitoring,control,protection,regulation,excitation,etc.

This paper dcals with five kinds of new siphonic inlets of small-sized hydropower stations,which have good developing prospects,for they not only are simple in struture, reliable to work,convenient to manage and against freeze,but also are able to save the gate and headstock gear equipments that cost more to build.
