| 摘 要： | 在瞬时无功功率理论的基础上,对农村电网的三相和单相电流的谐波成分进行了分析,同时对平均值谐波检测方法(又称积分法)的实时特性进行了分析。结果表明:三相对称电路在一定的情况下,谐波检测实时特性可以达到T/6,而单相电流中的谐波检测实时特性最多可以达T/2。通过Simulink仿真也表明,平均值谐波检测法具有较好的响应速度,检测结果准确,有较好的应用性。

| Abstract: | Based on the instantaneous reactive power theory,compared with the harmonic current in single-phase circuit about rurall power network,by analyzing the real-time character of the harmonic current average detection method (integral method),the real-time character of the average current in three-phase circuit can reach T/6,while only T/2 in single-phase circuit at most. The same value has also been obtained in simulink simulation. It is agreed that the detection value is accurate and the respond speed is fast... |
