Title:
CONVERTER-DRIVING DEVICE AND CONVERTER-CONTROLLING DEVICE IN WIND POWER GENERATION SYSTEM AND SWITCHING ELEMENT MODULE-DRIVING DEVICE AND SWITCHING ELEMENT MODULE-CONTROLLING DEVICE IN WIND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/171182
Kind Code:
A1
Abstract:
The present invention relates to a converter-driving device in a wind power generation system, a converter-controlling device in a wind power generation system, a switching element module-driving device in a wind power generation system, and a switching element module-controlling device in a wind power generation system. Disclosed specifically are: a technique for consecutively driving converters according to an increase in the power outputted to a system and consecutively stopping the driving of the converters according to a decrease in the power outputted to the system, thereby driving the converters according to a current system output; a technique for equalizing the driving times of the multiple, parallelly connected converters included in the wind power generation system, thereby maximizing the life of the converters; a technique for consecutively driving switching element modules, one by one, in case of an increase in the output power of the converters and consecutively stopping the driving of the switching element modules, one by one, in case of a decrease in the output power of the converters, thereby driving the switching element modules according to the size of the power currently being outputted by the converters; and a technique for varying the driving timings of the multiple switching element modules included in the converters, thereby minimizing harmonic components included in the alternating current generated by the converters.
