Abstract

when the wind power is connected to an electrical grid effects of the power quality. The effects of power quality measurements are the active power, reactive power, variation of voltage, flickers, harmonics and electrical behavior of the switching operation. The installation of the wind turbine with grid causes power quality problems determined by studying this paper. For this static compensator (STATCOM) with a battery energy storage system (BESS) at the point of common coupling to mitigate the power quality problems. The grid connected wind energy generation system for the power quality improvement by using STATCOM control scheme is simulated using SIMULINK power system blocked set. This is relives the main supply source from the reactive power demand of the load and induction generator in this proposed scheme. The improvement in the power quality on the grid has been presented here according to the guidelines specified in IEC-61400 standard (International Electro-technical commission) provides some norms and measurements.

statcom控制方案改善并网风电系统电能质量

当风力发电连接到电网时，对电能质量产生影响。电能质量测量的影响是有功功率、无功功率、电压变化、闪烁、谐波和开关操作的电气行为。通过本文的研究，确定了风电机组并网安装时产生的电能质量问题。对于静态补偿器(STATCOM)，在公共耦合点上采用电池储能系统(BESS)来缓解电能质量问题。利用SIMULINK电力系统阻塞集对并网风力发电系统采用STATCOM控制方案改善电能质量进行了仿真。这减轻了本方案中负荷和感应发电机无功需求的主要供电来源。根据IEC-61400标准(国际电工委员会)提供的一些规范和测量方法，介绍了电网电能质量的改善。
