Shaojun:IntroductionElectromagnetic compatibility is the ability of electrical and electronic equipment or systems to function normally in their electromagnetic environment without causing any adverse effects on anything in that environment: The ability to withstand electromagnetic disturbance: Electromagnetic compatibility is one of the important factors affecting the environment and product quality, and its standardization work has led to It has attracted widespread attention at home and abroad: In this regard, the IEC 61000 series of publications developed by the International Electrotechnical Commission (IEC ) is a Common standards in the fields of industry, electrical engineering and energy, transportation industry, social undertakings and health, consumer product quality and safety, etc:, are divided into There are 6 categories: overview, environment, limits, test and measurement technology, installation and mitigation guidelines, and general standards: Our country has launched a series of publications for this series Domestic transformation work has been carried out and a corresponding national standard system has been established: In this standard system, GB /Z 17624 "Overview of Electromagnetic Compatibility" is a basic standard in the field of electromagnetic compatibility, aiming to describe electrical Contents such as basic terms and definitions of magnetic compatibility, electromagnetic influence phenomena, historical basis, general parameters, etc: are planned to be composed of 8 parts: ---Application and explanation of basic terms and definitions of electromagnetic compatibility (GB/T 17624:1): The purpose is to describe and explain electromagnetic compatibility A variety of terms of great significance to basic concepts and practical applications in system design and evaluation: --- Methods for achieving functional safety of electrical and electronic systems of equipment related to electromagnetic phenomena (GB /Z

relationship under string conditions, in order to provide clear information on the definition of fundamental power factor and non-fundamental power factor, and provide technical committees, product Commissions and conformity assessment bodies provide advice on the content of power factors of single-phase systems under non-sinusoidal conditions, experiments with similar influencing quantities By comparing these reports between laboratories, various domestic technical committees related to electromagnetic compatibility have made a comprehensive assessment of single-phase systems under non-sinusoidal conditions: The power factor is handled consistently: Overview of electromagnetic compatibility part 7: non-sinusoidal conditions The power factor of a single-phase system1 ScopeThis document provides definitions of various electrical quantities and their relationships under non-sinusoidal conditions in order to address both components of power factor: This quantity provides unambiguous information: the fundamental power factor, resulting from the phase difference between the fundamental voltage and current, is related to the voltage and/or current distortion: Off the non-fundamental power factor: This document applies only to single-phase systems: This document applies to the following three situations: ---Generally, voltage and current are distorted (Chapter 5); ---The voltage is sinusoidal and the current has only distortion caused by harmonic components (Chapter 6); ---The special case where both voltage and current are sinusoidal (Appendix A): Appendix B

and definitionsThe following terms and definitions apply to this document: 3:1 root-mean-squarevalue root-mean-squarevalue rmsvaluermsvalue effectivevalueeffectivevalue For a time-related quantity, the positive square root of the average of the squares of the quantity over a given time interval: Note 1: The range of the integral interval of the root mean square value of a periodic quantity is usually a positive integer multiple of its period: Note 2: The root mean square value of the sinusoidal quantity a(t)=A^cos(ωt ϑ0) is Aeff=A^/2: Note 3: The root mean square value of a quantity can be represented by the sign of the quantity plus one of eff or rms as a subscript: Note 4: In electrical technology, the root mean square values of current i(t) and voltage u(t) are usually expressed as I and U respectively: [Source: GB/T 2900:92-2015,103-02-03] 3:2 direct componentdirectcomponent The average value of a quantity over a given time interval: [Source: GB/T 2900:92-2015, 103-06-05,
