Title:
DEVICE AND METHOD FOR LOW VOLTAGE RIDE-THROUGH OF WIND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/051175
Kind Code:
A1
Abstract:
The present invention relates to a device and a method for the low voltage ride-through of the systems of a wind power generator, wherein the low voltage ride-through of a wind power generator can be readily carried out using a bidirectional power conversion system and an energy storage system, and improvement in the quality of the wind power generation can be promoted. That is, the present invention is to provide an economical and efficient low voltage-ride through a device resolving the low voltage ride-through of systems by using the discharge capacity of the energy storage system with respect to a new wind power generator (plant) and the existing wind power generator (plant), wherein an energy storage system including a bidirectional power conversion system for charging or discharging electricity generated from a wind power generator connected to the system is provided and operated so as to meet the low voltage ride-through (LVRT) function required for the wind power generator (plant) when a low voltage below a predetermined level is generated in the system and maximize the electricity quality produced from the wind power generation.
