The relationships between generalized reactive power and waveforms of voltage andcurrent are analyzed by using the correlation techniques. The concepts of similarity and completesimilarity of voltage and current waveforms are proposed. With these concepts it is derived andproved that the generalized power factor is essentially a measure of the difference between voltageand current waveforms, while the reactive power is just the result of this difference. Two characteristic parameters, similarity coefficient and complete similarity coefficient of voltage and currentwaveforms, are given to evaluate the quality of electric energy. The similarity coefficient characterizes the degree of being distortionless and the symmetry of load current related to voltagesource. The complete similarity coefficient is equivalent to the generalized power factor and characterizes the efficiency of power delivery of power systems.

在应用相关技术分析电流电压波形与广义无功功率之间的关系的基础上,提出了电流电压波形相似和波形完全相似的概念,用此概念论证了广义功率因数是电流总体波形与电压总体波形完全相似程度的一种度量,明确了广义无功功率是由于电流总体波形与电压总体波形存在差异所造成的这一物理概念。文中还给出了电流电压波形相似系数和波形完全相似系数的定义式,其中波形相似系数描述了电流波形相对电压波形的非畸变程度和对称程度,波形完全相似系数等价于广义功率因数,表征了系统容量的利用率。

This paper presents a balanced 3/1 supply scheme for electrified railway. By employing an active filter, the current of the three phase power delivery system is balanced while the load is in single phase, which makes it possible for the traction system to behave like a three phase balanced pure resistance load to the power delivery system, with unity power factor and no harmonics. Simulation results are presented to verify the scheme′s topology and control regularity.

提出了一种三/单相平衡变换的铁路牵引供电系统方案.在负载为单相的情况下,采用有源滤波器,使得三相的电力系统的输出电流保持平衡.采用这个方案,将使铁路牵引系统表现为一个三相平衡的、纯阻性的、功率因数为“1”的、不产生谐波的电力系统的负载.为验证该方案的原理及控制规律的正确性,进行了仿真研究并给出了结果.
