摘　　要：为了提高蓄电池的可靠性、经济性以及整个船舶电力系统的安全性和可靠性,提出了一种由单片机控制智能晶闸管模块(ITPM)和电力电子(自关断)器件GTO对蓄电池进行充电的控制系统;针对交流三速电动起货机空钩、轻载效率低这一问题,采用单片机优化处理控制GTO调节起货机功率因数实现节能,同时使起货机在起动、变速和停车时具有平滑的性能;对于船舶空压机电动机过流保护存在的问题,提出了电流不对称保护与相敏保护相结合的数字式过流保护原理,采用双单片机控制GTO进行保护,增加了保护的可靠性。For boosting storage battery reliability, economy,as well as reliability and security of whole marine power station system, the method that is to use single chip computer to control Intelligent Thyristor Power Module and Gate Turn Off Thyristor in order to charge storage battery is put forward. Aiming at the low efficiency of AC（Alternating Current） three-speed motor hoist while empty hook and light loading, using single chip computer to control Gate Turn Off the power factor can be adjusted for energy-saving and smoothness can be achieved while starting, speed--changing or stopping. For the over big electric current protective problem that exists in the ship air compressor electric motor, the digital over current protective principle with the current dissymmetry protection and phase sensitivity protection is presented. Because of adopting the double microcomputer control GTO the protective dependability is increased.
