Problems solved by technology

[0003] The power fluctuation of wind power will cause the following two problems: first, the energy utilization efficiency is low, and the steady-state power is large at night, but the power consumption is small; second, the transient power fluctuation also causes problems such as low voltage ride through
However, wind power plants are mostly located in arid mountainous or semi-mountainous areas, and it is impossible to build pumped storage power stations

Abstract

The invention provides a wind power adjustment device storing energy by means of cableway transport. The device comprises a weight transfer unit, a high altitude weight treatment device, a low altitude weight treatment device, a drive device, a power generator, and a low voltage passage control unit, wherein the high altitude weight treatment device and the low altitude weight treatment device are arranged at two ends of the weight transfer unit, the drive device connected to the weight transfer unit is used for driving the weight transfer unit to operate, the power generator connected to the weight transfer unit is used for converting released energy into electric energy, and the low voltage passage control unit connected to the weight transfer unit is used for adjusting wind power. The wind power adjustment device has the advantages that energy can be converted efficiently, charging / discharging reaction speed is flexible to control, energy storage capacity is high, the device is environmentally friendly and low in construction cost and maintenance cost, and the scale is easy to control.

Description

technical field [0001] The invention belongs to the field of power generation / transmission, and in particular relates to a wind power power regulating device utilizing cableway transportation and energy storage. Background technique [0002] In recent years, with the increasing pressure on energy and environment, wind power, as the most mature renewable energy power generation technology, has developed rapidly. The output power of wind energy is naturally fluctuating. According to the characteristics of wind power fluctuations, power fluctuations can be divided into two categories: 1) transient fluctuation power P peak , caused by an instantaneous large increase or decrease in wind speed. The fluctuation amplitude is large, but the duration is small. 2) Steady-state fluctuating power P steady . The magnitude of the power fluctuation is small, but the proportion is large, the duration is long, and the energy fluctuation is large. [0003] The power fluctuation of wind p...
