【正文】 ss, bined the modules anic finally in order to realize the synthetic automatic control function. In this pointtopoint control system, the PLC can acplish the function which including automatic start and stop the generator, the frequency and load regulation, and treatment of machine or electric fault, etc. The upper puter realized automatic paralleling, disengaging, and asking overload, etc. Meanwhile HumanMachine Interaction can display and record the generators state and various parameters. This distribution control system fully embodies the advantages of distributed control and central management.

為實(shí)現(xiàn)船舶電站自動(dòng)化的各種 功能，船舶電站自動(dòng)化技術(shù)經(jīng)歷了由繼電器、接觸器組成的有觸點(diǎn)控制系統(tǒng)到有分立元件和集成元件組成的無(wú)觸點(diǎn)控制系統(tǒng)。同時(shí)，上位機(jī)的人機(jī)界面可以顯示、記錄機(jī)組的運(yùn)行狀態(tài)和主要參數(shù)。本文將電站的控制功能模塊化，再設(shè)計(jì)出各模塊的流程，然后將各模塊有機(jī)的結(jié)合，以實(shí)現(xiàn)電站的綜合自動(dòng)控制。
