With more generation from the onshore and offshore wind farms and thus increase in proportion from wind farms in the total system generation, the wind turbines exert more influence on the system and the regulation of parallel operation for the wind turbines has been becoming more and more stringent. The wind turbines are likely to be tripped off promptly under faulty conditions because of the system protection functions, and will cause severe imbalance between generation and load. Therefore, many utilities start drawing up regulations which require that the wind turbine should remain connected to the grid when a fault takes place in the system to help the system run through the fault. Such requirement is referred to as Low Voltage Ride Through. The main purpose of this thesis is to study the utilization of reactive power compensation for the enhancement of Low-Voltage-Ride-Through capability of wind turbines to prevent tripping of multiple wind turbines under system faults. Two sample systems are adopted as the study systems of which both the effects of incorporating wind turbines on the system voltage and the advantages of reactive power compensation for improving system dynamic characteristics are investigated. Comparisons are made about the performances of the wind farm equipped by SVC and STATCOM to improve the wind farm voltage during and after a fault. Moreover, the effects of the SVC and STATCOM device parameters on the system dynamic responses subject to system faults are also analyzed. Pei-Hwa Huang 黃培華 2013 學位論文 ; thesis 76 zh-TW |
