| 摘 要： | 分析了p q r法在电力系统谐波检测中的应用。详细讨论了三相四线制中电压有畸变和负载不对称时中线电流的抑制效果,从HyosungKim提出的p q r法的基本理论出发,通过理论分析和仿真证明p q r法在电压畸变明显时不能完全抑制谐波,而对无功补偿和中线电流抑制有较好的效果。

| Abstract: | The p-q-r theory, introduced by Hyosung Kim, is put forward for the power compensation and harmonic restraint in the paper.It analyzes how to eliminate the neutral-line current, when the source voltages are distorted and the loads are unbalanced in three-phase four-line system. Through theory analysis and simulation,it proves that the p-q-r theory can only eliminate harmonics partially. However, it can eliminate the neutral-line current and the instantaneous reactive power well.This project is supported by National Natural Science Foundation of China (No.2003ABA046). |
