Abstract

The present invention discloses a control method of an energy storage system for a wind turbine generation set and a communication management system which are used to ensure the safe operation of theenergy storage system in a normal condition or an extreme weather. The method comprises the steps that: an energy storage coordination controller obtains related information of a wind power plant andreal-time information of a wind turbine generation set; and the energy storage coordination controller issues a control command to the energy storage system according to the obtained information to control the energy storage system to be operated in a normal operation mode or a typhoon operation mode. The method controls the energy storage system to be switched between the two operation modes according to the information of the wind power plant and the wind turbine generation set to ensure the safe starting and operation of the energy storage system in the extreme condition. During the loss ofthe external power grid electric power support, the control method of an energy storage system for a wind turbine generation set and a communication management system supports normal operation of a power utilization system itself to effectively improve the safety of the wind turbine generation set. In the normal operation state of the wind turbine generation set, the charge-discharge energy storage system is controlled to achieve fan grid-connected power regulation and improve the unit online electric quantity.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a control method and a communication management system for an energy storage system of a wind turbine. Background technique [0002] Wind power is a new energy power generation technology that developed earlier and is now relatively mature, and its status has become increasingly important. With the gradual transfer of wind power technology from land to sea, offshore wind power has become the focus of renewable energy development. In order to ensure that the yaw system of the wind turbine can still operate normally when the external power grid is cut off, most of the existing wind turbines are equipped with a backup power supply. [0003] It is more common to use a diesel generator set as its backup power source. However, diesel generator sets have the problem of insufficient safety and reliability. Using the energy storage system as the backup power supply for wi...
