In order to ensure the safe stability and high efficiency of the operation way of system for power supply, most designs of system for power supply in transformer substation adopt operation way of double system for power supply at present.

Battery monitoring for a power system with back-up batteries;

Application of model-based fault diagnosis in aircraft power system;

Research on Motor Control and Power System of the Rehabilitation Manipulator;

Realization of over-voltage protection in dispatching power supply system;

Protection of electronic equipment s power supply system against over-voltage;

In the paper features of more electric aircraft are presented;advanced technologies for electric power systems for more electric aircraft are investigated;and electrical system architectures,electric power systems,power distribution systems,and automatic electric load management technique are discussed.

Fault modes of electric power systems in aircraft are often in the deviation of their measured values from the nominal ones.

Based on the analysis and sum-up of aircraft electric power system fault experience, a fault database is established, on which an artificial neural network-based aircraft electric power fault diagnosis system is designed and realized.
