Abstract

The Low Voltage Ride Through (LVRT) technology with low-speed direct-drive Permanent Magnet Synchronous Generator (PMSG) is studied in this paper. Based on the system structure and its controller options, a class of LVRT control strategies are proposed in terms of energy flow, which can make sufficient use of power characteristics of wind turbine and the large moment inertia of the system to achieve LVRT and are suitable for various running conditions. Simulation results verify that the proposed control strategy meet the LVRT requirements thoroughly and demonstrate superior dynamic performance.
