摘要: 为解决功率三角形不能解决的一些问题,例如求含谐波电流的非正弦电路的电气参数问题,根据电工理论提出了由视在功率S、有功功率P、无功功率Q和畸变功率N构成的功率四边形.功率四边形也可看成是由基波功率三角形和谐波功率三角形组成的.由功率四边形进一步确立了非正弦交流电路中的电流四边形和导纳四边形,以及它们和功率四边形的相似关系.以现场实测数据为例,利用四边形理论计算了非正弦交流电路中的畸变功率、谐波畸变角、总谐波电流、畸变导纳、谐波导纳等参数.Abstract: To solve problems that can not be solved using the power triangle,such as determining electric parameters in non-sinusoidal alternating-current circuits with harmonic currents,the power quadrilateral was proposed.A power quadrilateral consists of apparent power S,active power P,reactive power Q,and distortion power N,or is composed of a fundamental harmonic power triangle and a harmonic power triangle.Further,the current quadrilateral and admittance quadrilateral,as well as their similarity to the power quadrilateral in non-sinusoidal alternating-current circuits were derived.Electric parameters such as distortion power,harmonic distortion angle,total harmonic current,distortion admittance and harmonic admittance were calculated using the principle of the quadrilaterals and data collected in-situ.
