Energy conversion device and method

Abstract

The invention discloses an energy conversion device and method. The energy conversion device comprises an electric motor, a first transmission device, a hydraulic pump and an energy accumulator, wherein the electric motor is dynamically connected with the hydraulic pump through the first transmission device; and the hydraulic pump is connected with the energy accumulator through an oil way. The electricity is input into the electric motor, the hydraulic pump is driven by the first transmission device to work, and hydraulic oil is pumped into the energy accumulator through the hydraulic pump and stored in a hydraulic energy manner. Accordingly, by means of the method, the surplus electric energy can be stored. For example, as for an electric power plant, the surplus electric energy can be stored at the peak time of power generation and can be used in an electricity limitation period. Therefore, the pressure of the electric power plant can be released, and the pollution can be reduced. The energy conversion device is simple in structure and low in use cost, and can realize large-scale energy storage effects only under the condition that the volume of the energy accumulator is enlarged.

Description

technical field [0001] The invention relates to the field of energy, in particular to an energy conversion device and method. Background technique [0002] Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other power machinery. The energy generated by water flow, air flow, fuel combustion or nuclear fission, and the sun is converted into mechanical energy transmission. to the generator, and then converted into electrical energy by the generator. [0003] However, a problem currently exists is that in some cases, for power plants, there may be a peak period of power generation, and this peak period of power generation may correspond to a period of low power consumption. Therefore, during this time period In the interior, the electricity converted by the generator is excess, and the excess energy will cause energy waste and environmental pollution; at the same time...

Problems solved by technology

[0003] However, a problem currently exists is that in some cases, for power plants, there may be a peak period of power generation, and this peak period of power generation may correspond to a period of low power consumption. Therefore, during this time period In the interior, the electricity converted by the generator is excess, and the excess energy will cause energy waste and environmental pollution; at the same time, in other time periods, the power plant may be in the low peak period of power generation, but at this time it is in response to the peak power consumption During the period, there will be a situation in which electricity demand exceeds supply, which will affect industrial production and daily life.
