Characteristics analysis of wind farms for participating frequency regulation in Jilin power grid

摘要

This paper presents the characteristics analysis of wind farm to the participation of power grid frequency regulation. Wind farm is built by equivalent modeling method, and contains full-converter wind turbine generators (WTG) with Wind Turbine of Direct-Drive Permanent Magnet Synchronous Generator (DDPMSG). At first, model and control strategy of WTG with PMSG is introduced. Then single-machine equivalent model is elaborated. The control model of WTG with PMSG is built to reflect frequency adjustment. Combined with Jilin power grid data, wind farms are built on software of DIgSILENT/Power Factory platform. Output Characteristic of wind farm is analyzed under load shedding. Results show that control technology of the DDPMSG is suitable for contribution to grid frequency response.
