According to the six features of the Xiaoguanzi hydropower station s underground power house excavating, the construction technique countermeasures were elaborated and on strict construction management, based on safety and excellent quality, the excavating term was completed beforehand 75 days than the plan and realized the rapid construction aim.

Construction of the bridge for diversion tunnel in Xiaoguanzi Hydropower Station;

Online process control of supervisory control system for small hydropower station;

The Research and Development of the Integrated Mearsuring and Control Device Based on DSP for Small Hydropower Stations;

The running condition assessment of small hydropower station involves various aspects and multilayer analysis and has vagueness and uncertainty,so that the evaluation can be only qualitative analyzed and difficult to be quantified directly.

Langshan area will accelerate the development of small-size hydropower stations in the future years because of its abundant water resources.

Research and practice of optimum operation method based on genetic algorithm for small hydropower stations;

Through analysis of the specialty of annual power generation series of small hydropower stations,a regression model based on the least squares support vector machine(LS-SVM) was introduced into the field of annual energy production forecasting in this paper.

Stability analysis of high inlet slope for Xiaowan Hydropower Station;

In the Feasibility Report of Xiaowan Hydropower Station,construction schedule will be much slowed down due to more orifices in the dam body,reservoir filling will start 12 years later after the construction of reservoir has begun.

Prior to the joint grouting work of the Xiaowan hydropower station,we conduct indoor and On-site slurry performance tests which provide scheme and basis for the construction.
