The objective of the paper detailed investigation some problem which exist in design,such as:student apartment flux,electricity load,power distribution and socket system,student apartment building ground fault protection and lightning protection,telephone system,network system,then provide some suggestion to that problem,to give a reference for the electric design of the similar projects.

This paper focuses on some new ideas on electrical design in the college dormitories during a new period of rear-service reform,which include the safe use of electricity,intelligent power management and college dormitories electricity load,etc.

Chaotic characters of power load and its forecasting for marine electric propulsion system;

Research and comparison of neural networks for forecasting mid-long term power load;

Gray neural network forecast of power loads based on relaitonal analysis method;

ammonia pump and its main parame-ters,analyzes the reasons for such respects as trip at low electric charge,leakage of mechanical seal,shaft vibration and displacing upward as well as the motor's bush being burnt,and puts forward somesolutions.
