中文摘要	为了克服传统检测方法在非正弦不平衡系统中检测的单一性,在对称分量法基础上提出一种计算矩阵,可将任意次的正、负、零序电流,广义无功电流,以及各相中的不平衡谐波、不平衡有功、不平衡无功电流,单相基波功率因数等参量一次计算出来。该方法的原理是在检测出基波不平衡电流的基础上利用幅相计算原理建立计算矩阵,即可方便计算出多种电参量。该方法可用于三相三线(四线)制和单相系统中,对电力系统自动化装置的检测及各种拓扑结构的电能质量治理装置的补偿量检测也适用,尤其在要考虑装置补偿容量以及装置能否补偿有功功率不平衡时可进行灵活选择补偿。理论分析和算例实验均表明了该方法的正确性和可行性。; In order to overcome the oneness of the traditional detection method in the non-sinusoidal and unbalanced system,this paper presents a new kind of calculation matrix based on the symmetric component method.It can easily calculate the positive/negative/zero-sequence and generalized reactive current,it can also calculate the asymmetric harmonic and asymmetric active/reactive current,and the three-phase power factors,etc at one go.Using the principle of amplitude-phase to build the calculation matrix that can easily calculate many parameters based on unbalanced fundamental current,which is the calculation principle.This method can be used for the three-phase three-wire(or four-wire)system,single-phase system,as it can for the automation of electric power systems,and it may be also convenient for the detection system of a variety of power quality control devices.And we can easily set the function of those devices when considering their compensation capacity and whether they can compensate for the unbalance of the active power.Finally,the theoretical analysis and experimental results both show the validity and feasibility of the method.
