A kind of micro wind turbine control method of wind turbine backup power supply system

Abstract

The invention discloses a micro wind driven generator control method of a wind turbine generator standby power supply system. According to the method, a current transformer of the standby power supplysystem is utilized, the micro wind driven generator is controlled to run in different control modes according to the weather conditions, the optimal control of the micro wind driven generator in thestandby power supply system is realized; the current transformer does not participate in the control of a main unit and the full-field control, a control instruction of the micro wind driven generatoris given according to the acquired full-field information and the real-time information of the unit are acquired and the running condition of the micro wind driven generator, the control mode is divided into a normal outage mode, a normal standby mode and a typhoon operation mode. According to the device, the self-electricity-utilization system of the main unit set can be ensured to operate safely under extreme conditions, when the wind turbine generator loses the external power grid electric power support, normal operation of the yaw system is supported, and the safety of the wind turbine generator is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric energy management, in particular to a control method for a miniature wind power generator of a backup power supply system of a wind power unit. Background technique [0002] It is known in the industry that the micro wind power generation system is used as the power source of the backup power supply system of the wind turbine to solve the problem of insufficient safety and reliability of the diesel generator set and improve the disaster resistance of the wind turbine. The micro wind power generation system is used as a backup power supply. At this time, two issues need to be considered: 1) the control structure of the self-consumption backup power supply system; 2) the control strategy of the backup power supply system. At present, the self-consumption backup power supply system using micro wind turbines as anti-typhoon units lacks a suitable control structure and strategy to ensure the safety an...
