●电能质量的基本描述      BASIC DESCRIPTION OF POWER QUALITY

电能质量是指电力系统中电能的质量,主要以电流质量指标、频率质量指标和电压质量指标来衡量。频率质量指标为频率允许偏差;电压质量指标包括幅值质量和波形质量。其中电压质量包括供电电压允许偏差、电压波动和闪变、三相电压允许不平衡度、暂态过电压和瞬态过电压;电流质量为公用电网电流谐波的容许值。

Power quality refers to the quality of electrical energy in a power system, mainly measured by current quality indicators, frequency quality indicators, and voltage quality indicators. The frequency quality indicator is the frequency tolerance; the voltage quality indicator includes the magnitude quality and the waveform quality. The voltage quality includes the supply voltage allowable deviation, voltage fluctuation and flicker, three-phase voltage allowable imbalance, transient over-voltage and transient over-voltage; the current quality is the allowable value of the utility grid current harmonic.

 

●电能质量产生的源头      SOLUTION OF POWER QUALITY

不完全取决于电力生产企业,有的指标(如谐波、电压波动和闪变、三相不平衡度)往往是由用户干扰所造成的。保障电能质量,既是电力企业的责任,也是用户(干扰性负荷)应尽的义务。各方应该按照现有的国家标准来规范有关电能质量的问题,要保证电能在额定的电压、频率范围内的正弦波形,还应保证不平衡度(瞬态的、稳态的)、电压波动和闪变在国家标准之内。

Not entirely dependent on power producers, some indicators (such as harmonics, voltage fluctuations and flicker, three-phase unbalance) are often caused by user interference. Ensuring the quality of power is both the responsibility of the power company and the obligation of the user (interfering load). All parties should standardize the issue of power quality in accordance with existing national standards, ensure sinusoidal waveforms of electrical energy within the rated voltage and frequency range, and ensure unbalance (transient, steady state) and voltage fluctuations. And flicker is within national standards.
