Embodiment 1

[0055] 1 power supply scheme

[0056] According to the two problems of the huge amount of abandoned wind in wind farms and the high power consumption of tower elevators, a power supply mode of "wind power abandoned wind power + energy storage compensation power = elevator power consumption" is proposed. When there is abandoned wind, use the abandoned wind to power the tower elevator; when there is no abandoned wind, use the energy storage system to power the tower elevator; when the amount of abandoned air is sufficient, the energy storage system is charged. Power supply mode such as figure 1 .

[0057] The tower elevator power supply mode based on the abandoned wind not only achieves the purpose of using the abandoned wind as the power supply for the tower elevator, but also solves the power supply of the tower elevator when there is no abandoned wind. Make full use of the abandoned wind to power the tower elevator and solve the problem of high power consumption of the towe...

Abstract

The present invention relates to the technical field of power supply for tower elevators in wind farms, in particular to a power supply method for tower elevators and an energy storage system based on the use of abandoned wind, which uses the amount of abandoned wind power to supply power for tower elevators and uses the energy storage system when the abandoned wind is insufficient The power supply mode used as a supplementary power supply for tower elevators. Aiming at optimizing the economical configuration of the energy storage system, a model of the tower elevator energy storage system was established, and the energy storage configuration was optimized using a genetic algorithm (GS). The actual statistical data of a wind farm in Xinjiang is used to statistically calculate the abandoned wind power of the wind farm and the power used by the tower elevator. The required configuration of energy storage power and charging and discharging power is calculated through calculation examples, and the parameters of the energy storage system are optimized to minimize the operating cost of the energy storage system. The invention solves the problem of high power consumption of the tower elevator and achieves the purpose of saving energy and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of power supply for tower elevators in wind farms, in particular to a power supply method and energy storage system for tower elevators based on abandoned wind utilization. Background technique [0002] At present, the earth's fossil energy is gradually exhausted, so the utilization of renewable energy is widely concerned at home and abroad. As a renewable energy, the installed capacity of wind power is continuously expanding. In order to ensure the safety of wind turbine maintenance and improve the efficiency of maintenance and inspection, many wind turbines have been equipped with tower elevators for wind turbine maintenance. However, the extra power consumption of the tower elevator requires the wind power plant to re-purchase power, which increases the cost of power generation. Behind the continuous growth of wind power, due to the constraints of the conventional power reserve capacity of the power grid...
