The paper reviews the re-cent achievements of passenger transportation work of slow trains and at small stations from the aspects of safety transportation, the prevention of unhealthy ten-dancies, equipment and facilities, service quality and management.

With the growth of railroad traffic mileage,the moderate and small stations increase.

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.
