Title:
METHOD FOR COORDINATING CONTROL OF WIND FARM DURING BLACK START OF ISLANDING OPERATION
Document Type and Number:
WIPO Patent Application WO/2016/070319
Kind Code:
A1
Abstract:
A method for coordinating control of a wind farm (1) during black start of islanding operation, including: selecting a conductor in the wind farm (1) via which the external generator (9) is electrically connectable to auxiliary equipment of at least one wind turbine(10-15, 20-25, 30-35) of the wind farm (1) to deliver the active power to the auxiliary equipment of the wind turbine (10-15, 20-25, 30-35), wherein the selected conductor is electrically connectable to a converter (101-151, 201-251, 301-351) of the wind turbine (10-15, 20-25, 30-35); and choosing at least one of the wind turbines (10-15, 20-25, 30-35), wherein a converter (101-151, 201-251, 301-351) of the chosen wind turbine (10) can absorb a portion of an amount of reactive power generated by the selected conductor when voltage is applied between at least two parts of the selected conductor; operating an external generator (9) in an operation region around power limit curve to output energy; electrically connecting the output of the external generator (9) and the auxiliary equipment of the wind turbine (10-15, 20-25, 30-35) via the selected conductor; electrically connecting the output of the external generator (9) and the chosen wind turbine (10-15, 20-25, 30-35) converter via the selected conductor; and absorbing by the external generator (9) and the chosen wind turbine (10-15, 20-25, 30-35) converter (101-151, 201-251, 301-351) the reactive power generated by the selected conductor so that an operation point of the external generator (9) is kept within the operation region around the power limit curve. By having the method,the external generator's available capacity can be fully utilized.
