Combined wind energy and hydraulic power varying generator

Abstract

The wind energy hydraulic power varying generator is one wind force power generator to convert wind energy into hydraulic energy to drive great power generator to produce electric power. The structural principle of the present invention is that the kinetic energy of several wind wheels are combined and converted into hydraulic energy mechanically, and the hydraulic energy is integrated into one powerful hydraulic transmission mechanism and used in driving one great power generator. The present invention has computer control to regulate hydraulic transmission and to stabilize rotation speed, and generator with varying power to output voltage. The present invention has simple structure, easy manufacture, low cost and great electrical power.

Description

1. Technical field: [0001] The invention relates to a wind power generating equipment which converts wind energy into hydraulic energy in a combined form to provide kinetic energy for a generator, and then drives a high-power generator to generate electricity. Two background technologies: [0002] The current wind power generation equipment is that the wind wheel rotates through the variable speed and the adjustment device directly drives the generator to generate electricity. The following problems exist in long-term operation: [0003] 1. Since most of the current wind power generation equipment weighs several tons, all of which are erected on columns with a height of 30 meters to 60 meters, the requirements for the strength, rigidity, stability and safety of the columns are extremely high, which increases the manufacturing cost, The difficulty of transportation, erection, monitoring and maintenance. [0004] 2. Due to the erratic and random nature of the wind energy, the...

Problems solved by technology

[0003] 1. Since most of the current wind power generation equipment weighs several tons, all of which are erected on columns with a height of 30 meters to 60 meters, the requirements for the strength, rigidity, stability and safety of the columns are extremely high, which increases the manufacturing cost, Difficulty in transportation, erection, monitoring and maintenance

[0004] 2. Due to the erratic and random wind energy in nature, the adjustment requirements for constant-speed power generation of generators are very strict, the design of the speed control device is very complicated, and the precision requirements are extremely high, which increases the manufacturing and production costs.

Due to the high cost of manufacturing and equipment installation, the on-grid electricity price of wind power is as high as 0.9 yuan / kwh, which is much higher than the on-grid electricity price of thermal power. National policy support and subsidies are still needed to solve the overpriced part of the on-grid electricity, which affects the government and enterprises. Enthusiasm and enthusiasm for wind power, slow investment and development, have restricted the development and utilization of renewable, green, and zero-pollution wind energy in my country, and affected the rapid development of wind power in China
