State Assessment Method and Results of Electric Emergency Diesel Engine Power Supply Vehicle

Zi-chong ZHANG, Jian FANG, Hong-bin WANG


Diesel engine power supply vehicle plays an important role in emergency electric repair of sudden disasters. Its reliability largely determines the efficiency of restoring power supply. This paper proposed a deduction system state assessment method based on performance testing, and evaluated 47 diesel engine power supply vehicles. The state assessment found that more than half of the power supply vehicles were not in normal state, and the transient performance of the power supply vehicles deteriorated seriously, requiring maintenance and repair. The factors that affect the state deterioration of power supply vehicles are studied, and it is found that the state deterioration of power supply vehicles with long service time and small rated capacity is more obvious.
