Abstract

The growth of wind farms in Brazil brings new challenges to the Brazilian electrical system, such as the adequacy of regulation for system operation, the supply-demand balance, the quality of the supplied power, and the system stability. New technologies associated with smart grids will enable an increase in intermittent renewable sources connected to the power distribution system. D-STATCOM (Distribution Static Synchronous Compensator) provides the necessary resources to prevent technical problems in systems with high penetration of wind power plants. It makes possible the wind farms to meet the requirements of network connection as power factor, voltage output and fault ride through requirements, as well as increases the transmission capacity and the network stability. This paper presents the dynamic behavior obtained by computer simulation of a distribution grid at 34.5 kV with D-STATCOM and wind farms. The use of D-STATCOM contributed to increasing the stability margin of the system, allowing the permanence of the three wind farms during fault and post-fault conditions.

D-STATCOM在风电场智能配电网中的应用

巴西风电场的发展给巴西电力系统带来了新的挑战，如系统运行监管的充足性、供需平衡、供电质量、系统稳定性等。与智能电网相关的新技术将使连接到配电系统的间歇性可再生能源增加。D-STATCOM(配电静态同步补偿器)提供了必要的资源，以防止在风力发电厂高渗透的系统中出现技术问题。使风电场在满足功率因数、电压输出和故障穿越等并网要求的同时，增加了输电容量和电网的稳定性。本文介绍了采用D-STATCOM和风电场对34.5 kV配电网进行计算机仿真得到的配电网动态特性。D-STATCOM的使用有助于增加系统的稳定裕度，使三个风电场在故障和故障后的情况下保持稳定。
