Description
Technical field
The utility model relates to boat-carrying winch field, ocean, particularly a kind of ocean boat-carrying AC frequency conversion winch active compensation control system.
Background technology
Along with population sharply expand, land resources is day by day exhausted, countries in the world focus on the ocean of be richly stored with oil, natural gas source and mineral resources.Since new century, many countries formulate ocean development strategy one after another, by exploitation marine resources, Development of Marine economy, control the grand strategy decision-making that ocean energy masterpiece is country, using building ocean power as the important measures strengthening overall national strength.In order to realize exploration of ocean resources and exploitation, special offshore engineering equipment must be had, and ocean boat-carrying winch is the crucial deck machinery equipment realizing resource exploration and development equipment folding and unfolding, the lash ships such as main support Scientific Research Ship, exploration of ocean resources ship, ocean engineering support boat, are widely used in exploration of ocean resources and deep ocean work.In region, deep-sea, the sea conditions very severe on sea, lash ship is by stormy waves, the impact of shoving and do fitfull rippling, 4 grades of sea situation wave wave height can arrive 2.5m, cause exploration of ocean resources and the development equipment heave thereupon of boat-carrying winch and folding and unfolding thereof, because exploration of ocean resources and development equipment transfer to abyssal environment to carry out operation, and Seawater has larger damping, armouring umbilical cables longer (3000-4500m), cylinder inertia is large, therefore whole boat-carrying winch extension and retraction system has stronger hysteresis quality, when lash ship rises with wave, armouring umbilical cables tension force increases, the most dangerous situation armouring umbilical cables is directly pulled off, when lash ship declines with wave, armouring umbilical cables tension force reduces, the most dangerous situation can make to be in dissociated state by the equipment of hanging, due to all comparatively valuable by retractable equipment, the appearance of these situations all can cause sizable economic loss, even if there will not be above-mentioned most dangerous situation, stress in armouring umbilical cables can not change with the heave of lash ship, armouring umbilical cables is caused to produce endurance failure, shorten its service life, have influence on the safety of operation.
The type of drive of winch mainly contains three classes such as diesel-engined drive, hydraulic-driven and electric drive.Wherein, diesel-engined driven winch, mostly adopt the mode of multiaxis and chain gear, structure comparatively complexity is eliminated gradually; Hydraulically-powered winch is still the dominant form of winch for ship at present, the advantages such as hydraulically-powered winch has compact conformation, power-weight ratio is high, drive torque is large, starting is steady, speed governing is convenient, safe and reliable, but control system falls behind relatively, power consumption is large, speed of response is slow; Electrical drawworks comprises DC powered and alternating current drives, DC powered winch has good speed adjustment features, efficiency is high, fast response time, drive torque are large advantage, but there is sparking at the brushes hidden danger, complex structure, and along with the development of high power AC variable-frequency control technique, AC inverter driving system winch has better development prospect.
Heave compensation system mainly contains passive heave compensation, active compensation and half active compensation three class.Passive heave compensation system does not need the external world to provide energy, direct dependence accumulator absorbs and releases energy, thus the energy that feedback lash ship heave movement load consumes, system is relatively simple, but compensation performance is unstable, hysteresis quality is comparatively large, compensation precision is low.Active Heave Compensation System is on the basis of traditional winch, increase detection and controller, the data such as real-time detection lash ship heave movement state, load, after controller process, export control signal control the rotating speed of CD-ROM drive motor and turn to and realize active compensation, there is the features such as antijamming capability is strong, comformability good, compensation precision is high, compensation performance is stable, do not need to increase extra equipment, and it is few to take workboat between deck space.Half Active Heave Compensation System combines both advantage, keep higher compensation precision to reduce energy consumption again, but structure is comparatively complicated.
In order to reduce the impact of lash ship heave movement on under-water operation, lot of domestic and foreign expert has also carried out large quantifier elimination to the aspect such as heave compensation, constant-tension control method of dissimilar ocean winch.Research mainly concentrates on all kinds of heave compensations, the tension control method of hydraulically-powered winch, and it is little in the compensation method research of electrical drawworks, only have yellow Lu Meng etc. to propose a kind of electronic ocean winch active heave compensation winch scheme in " active marine drilling heave compensation winch design and simulation study ", adopt positive and negative the transferring of separate unit alternating-current variable frequency motor Direct driver winch drum to realize heave compensation.And adopt feedforward-Fuzzy PI to control, overcome the deficiency of feed forward control, improve system rejection to disturbance ability and stability to a certain extent.
