Disclosed in the utility model, controlled and detecting and analysing system is stablized in a kind of wave energy power station, and specific works principle is as follows:
Vibration float 21 in water or marine floating, be subject to wave stroke after vibration float 21 do hang down swing, surging, pitching direction motion.Drive linear electric generator mover 44 to pump by self-adaptation lever 31, make the permanent magnet cutting straight line generator unit stator winding 46 on linear electric generator mover 44 produce three-phase alternating current.A pair primary importance sensor 47 is arranged outside guide pole 43, in the fixed cover 41 that these two primary importance sensors 47 are arranged on the up stroke terminal of guide pole 43 and relative position stagger, the direction of motion of the movement velocity of detection of straight lines generator rotor 44, top dead centre (dead point) and mover.Guide pole 43 upward stroke terminal has spring 42 to be arranged on fixed cover 41 li, prevents guide pole 43 from directly clashing into fixed cover 41, can also produce return action power when guide pole 43 clashes into this spring 42 simultaneously; A pair second place sensor 48 is also arranged in mover connecting rod 45 outside, these two second place sensors 48 are arranged on the place of mover connecting rod 45 down stroke terminal, and relative position staggers, the lower dead center of detection of straight lines generator rotor 44, prevents linear electric generator mover 44 from moving downward and goes beyond the scope.
Host computer 6 receives the signal of a pair primary importance sensor 47, a pair second place sensor 48 respectively, thus obtains movement velocity, the direction of motion of linear electric generator mover 44 and the scope that moves up and down.The adjustable support 324 of self-adaptation lever assembly 3 regulates the position of the fulcrum of self-adaptation lever 31, and the movement travel guaranteeing linear electric generator mover 44 is thereon in lower dead center.Host computer 6 is by a pair primary importance sensor 47, the instruction of a pair second place sensor 48 detection of straight lines generator rotor 44 motion state formation control; When linear electric generator mover 44 arrives upper and lower dead-centre position, host computer 6 sends and makes the first motor 322 rotation command, the first motor 322 is driven to drive leading screw 323 to rotate, slide block 324 is made to drive self-adaptation lever 31 to move right, thus reduce the amplitude that moves up and down of linear electric generator mover 44, until host computer 6 obtain linear electric generator mover 44 no longer exceed upper and lower stop limit scope time, host computer 6 drives the first motor 322 to stop operating by control first AC converter 321.When linear electric generator mover 44 motion amplitude is less, also when namely a pair primary importance sensor 47, a pair second place sensor 48 detection of straight lines generator rotor 44 do not operate in full stroke, host computer 21 drives the first motor 322 to rotate by control first AC converter 321, make slide block 324 drive self-adaptation lever 31 to be moved to the left, thus increase the amplitude that moves up and down of linear electric generator mover 44.
