In this paper, the hydraulic coupling is taken as the research object, and the important protection logic and parameter indexes are proposed in combination with its working characteristics, use function and protection mechanism. By studying the interlock protection control scheme of hydraulic coupling, the heater control scheme of hydraulic coupling, the auxiliary oil pump control scheme of hydraulic coupling and the speed regulation control scheme of hydraulic coupling, an independent and complete comprehensive control scheme of hydraulic coupling is proposed, which effectively solves the problems of imperfect starting scheme of hydraulic coupling, unstable operation of unit, unsafe use of heater and auxiliary oil pump and difficult control of speed regulation.
