This algorithm needs shorter data window time and has higher calculation precision and is not affected by deviation of powerfrequency.
这种算法具有所需数据窗的时间短、计算精度高和不受系统频率偏差影响的优点。

At present, our country power quality national standard was chiefly stipulated five quotas: frequency, harmonic and voltage deviation, three-phase unbalance and the voltage fluctuation and flicker.
目前我国电能质量国家标准主要规定了五个指标：频率、谐波、电压偏差、三相不平衡及电压波动与闪变。

Amplitude deviation, frequencydeviation and phase deviation are basic power quality disturbances.
