摘要
对微网中电能质量问题的主要产生原因和传播特点作了细致的总结和分析。分析指出微网电能质量的特点主要由微电源、网络和负荷性质决定,在此基础上介绍了针对微网的有源滤波补偿措施;介绍了微网中能完成有源滤波任务的设备及他们的结构和应用范围,指出有源滤波器与微电源相结合可保证有源滤波器发挥最大电能质量补偿能力;最后指出有效利用微网中存在的大量逆变/整流装置将是解决微网电能质量问题的主要途径。
This paper presented a detailed analysis and summary on the features of power quality issues in mierogrid. The resuits pointed out that the characteristic of power quality issues in Mierogrid depends on the composition of micro sources, the condition of network, and the chaxaeteristie of the loads. Base on this conclusion, active power filter oompensation solutions for power quality problem were introduced and then the common units in mierogrld that can be used as active power filter were in vestigated from the aspects of structure and application area. After investigation, the combination of APF and micro source were proved to ensure APF releasing its max power quality compensation capability. Finally, it pointed out that most inverters e quipped in microgrid could be effective tools for solving Power quality problems.
