新型注入式混合有源滤波器中无源滤波器的优化设计

Optimal Design of Passive Power Filter in New Injection Type Hybrid Active Power Filter

混合型有源滤波器能否按其工作原理实现预期的谐波抑制效果,在很大程度上还有赖于无源滤波器的优化设计。以一种新型注入式混合有源滤波器为例,该文对无源滤波器的优化设计问题进行了研究,给出了设计时所应遵循的一般性原则和安全性、可靠性原则;探讨了三相干式空心电抗器组的不同排列方式对电抗器品质因数的影响。工程应用效果验证了该文理论分析的正确性,相关分析方法和结论可为其它类型的混合有源滤波器中无源滤波器的优化设计提供借鉴。

Whether the hybrid active power filter （HAPF） could or not get desirable harmonic eliminating effect, it mainly depends on the optimal design of passive power filter （PPF）. Taking a new injection type HAPF as an example, this paper studies the design methods of PPFs in the proposed topology structure, presents general principles and gives some considerations on safety and reliability, and analyzes the arrangements of the three-phase reactor groups. The demonstration result in the engineering application verifies the above mentioned theory, and the harmonic suppression effect is remarkable. The methods for theoretical analysis and relative conclusions can be used as references for the design of PPF for other type of HAPE.
