【摘要】 为了研究利用有源电力滤波器对配电系统在谐振状态下进行谐波治理的问题,本文首先对配电系统的谐振原理进行理论分析,得到影响配电网谐振频率的因素;然后利用谐波电流注入法来检测配电系统的谐振频率,随后提取谐振频率附近的谐波电压作为阻尼电流,构建"虚拟电阻"对配电系统进行谐振阻尼;最后实验证明了有源电力滤波器能够有效的对谐振状态下的配电系统进行谐波治理。更多还原

【Abstract】 In order to study the harmonic compensation issues of distribution system at the resonance state based on SAPF, firstly the resonance principle of distribution system is analyzed, and the factors affecting resonance frequency are obtained. Then the method of harmonic current injection is used detect the resonance frequency of distribution system, and the harmonic voltage near the resonance frequ ency is extracted to be the damping current, which builds virtual resistance for resonance damping. At last, experiment proves that the harmonic compensation issues of distribution system at the resonance state can be effectively solved by the active power filter.更多还原
