Blade-type energy recovery shock absorber

The invention relates to a blade-type energy recovery shock absorber which utilizes a machine-electricity-fluid mixed system. The blade-type energy recovery shock absorber comprises a generator, a hydraulic motor, an energy accumulator, a hydraulic check oil way and a blade-type shock absorber assembly. By adopting the shock absorber, the linear motion between sprung mass and unsprung mass of a suspension system caused by unevenness of the ground is changed into hydraulic flow with invariable direction to drive the hydraulic motor to rotate, the hydraulic motor drives the generator to generate electricity, so that the vibration mechanical energy is converted into electric energy and recycled; the hydraulic check oil way consists of a hydraulic pipeline and a check valve system; the damping force required by the shock absorber system is mainly provided by the counter-acting force of counter electromotive force generated during operation of the generator, and active or semi-active control on the damping force of the shock absorber is realized by controlling the load of the generator. The blade-type energy recover shock absorber can be applied to a tracked vehicle in replacement of a traditional blade-type shock absorber, and is especially suitable for tracked vehicles with large electrical load. The vibration energy is recovered while the driving comfort is improved.

A seamless switching control method for AC/DC parallel systems based on vsc-hvdc

The invention provides an alternating current-direct current parallel system seamless switching control method based on VSC-HVDC. According to the method, the phase shift angle delta, relative to a voltage vector Uw of a wind power plant PCC point, of a voltage vector Us of a power grid connected with an alternating current circuit is adjusted by controlling a synchronous rotation angle theta of a VSC-HVDC wind power plant side convertor station so that active power transmitted by an alternating current power transmission circuit can be controlled, and the rest of the active power is completely absorbed by a VSC-HVDC power transmission system. As the phase position of the voltage of the wind power plant PCC point is controlled to be ahead of the phase position of the voltage of the alternating current power grid all the time, the current of the alternating current power transmission circuit will not turn over; when the alternating current circuit stops operating, any external signal does not need to be detected, the control mode of the VSC-HVDC wind power plant side convertor station does not need to be changed either, and when the alternating current-direct current parallel operation mode is converted into the operation mode that wind power has access to the VSC-HVDC independently, all wind power is absorbed automatically.
