Progressive distribution type ocean current energy hydraulic transmission generator set and control method thereof

Abstract

The invention relates to a progressive distribution type ocean current energy hydraulic transmission generator set and a control method thereof. The generator set comprises an ocean current energy capturing device, a hydraulic transmission power generation device and a control system connected with the hydraulic transmission power generation device, wherein the hydraulic transmission power generation device comprises an oil supplementing system, a variable motor and a synchronous generator which is coaxially arranged with the variable motor; the ocean current energy capturing device comprises impellers and a quantitative pump, wherein the impeller and the quantitative pump are coaxially connected, and each coaxial impeller and the quantitative pump form a turbine device; a high-pressure port of the quantitative pump is connected with an oil inlet of the variable motor through a high-pressure loop, a low-pressure port of the quantitative pump is connected with an oil outlet of the variable motor through an oil supplementing oil tank of the oil supplementing system to form an open-type volume speed regulating loop; the control system is connected with the variable motor and is used for adjusting the constant-speed operation of the variable motor, all the impellers of the turbine devices keep the same axis, and the diversion of the impellers are kept in a reverse coaxial rotation direction, and is integrally presented with the progressive distribution manner.

Description

technical field [0001] The invention belongs to the field of new energy power generation, and relates to a power generation device, in particular to a progressively distributed ocean current energy hydraulic drive generator set and a control method thereof. Background technique [0002] Energy and the environment are the material basis for the survival and development of human society. Conventional energy such as coal, oil, and natural gas not only has limited reserves, but also causes global climate warming and air pollution. With the rapid development of social economy, the effective use of clean and renewable marine energy has become a strategic choice for major coastal countries in the world. Ocean current energy is an important part of renewable energy. In recent years, it has been paid attention to by countries all over the world and has developed very rapidly. [0003] Ocean current energy is a kind of marine energy, which refers to the kinetic energy of seawater flo...
