A New Instantaneous Reactive Current and Power Analysis Based on pq Decomposing

LIU Jin-hua1,LIU Yong-qiang2(1 Zhongshan Institute of UESTC,Zhongshan 528403,Guangdong,China.2.South China University of Technology,Guangzhou 510640,China)  
How to define instantaneous reactive current and reactive power in three-phase non-sinusoidal asymmetrical systems is still a concerned problem by academia.From the view of assessing reactive power in power system,this paper discusses the properties of the instantaneous current and instantaneous reactive power in detail.By decomposing instantaneous current into p-axis and q-axis components(The voltage vector [ua,ub,uc]T is regarded to be located at p-axis),then the corresponding reactive power of p-axis and q-axis is given,and point that the current of p-axis contains instantaneous reactive current component ip2 except active current ip.So the instantaneous reactive power is composed of q-axis and p-axis instantaneous reactive power.And if zero sequence voltage doesn't exist,then p-axis instantaneous reactive power doesn't exist,and q-axis instantaneous reactive power denotes the power between phase loads.Furthermore,if zero sequence current is also zero,then the instantaneous reactive power is just the instantaneous reactive power defined by Akagi.
