【 摘 要 】

This paper proposes a new Fault Ride Through (FRT) method of Permanent Magnetic Synchronous Generator (PMSG) wind energy system based on the improved machine-side generator (MSC) control and superconducting magnetic energy storage (SMES) under grid symmetric fault condition. The system topology and basic principle of the proposed scheme are investigated in detail. The control strategies of improved MSC control and SMES are also presented. Furthermore, the simulation of PMSG integrated with the proposed scheme is conducted in PSCAD/EMTDC. Simulations show that the proposed FRT method could maintain key parameters of PMSG within the acceptable range and the capital cost of SMES is also reduced during grid fault, which demonstrates its feasibility and practicability.
