摘要
针对微电网中的电能质量治理问题,提出一种用于改善电能质量的补偿装置设计方案。它在原有混合型有源电力滤波器(HAPF)基础上增加了分布式电源及储能元件,采用一种改进型i_d-i_q复合指令电流检测及合成实现方法,较好地实现了一机多能的要求。该装置在有效解决微电网谐波和无功电流补偿的同时,也能较好地实现分布式电源并网发电功能,最大程度节约了治理成本。仿真与实验运行数据表明,该设计方案有效、可靠。
According to the power quality management problem of microgrid, a kind of the compensation device design scheme which is used to improve the power quality is put forward.It adds the distribution generation and energy stor- age components based on the original hybrid active power fiher（HAPF）.Adopting an implementation method which bases on improved id-iq composite instructions electric current detection and synthesis,realizing a machine has a vari- ety of functions well.The device can realize grid-connected power generation of distributed generation and do not af- fect the original improve power quality function of HAPF, achieve the full extent of the man-agement cost saving.Fi- nally, simulation and experimental results show that the design scheme and test device are efficient and reliable.
