Power Quality and Economic Evaluation
Part 1. Economic evaluation methods for power users
1 Scope
This section standardizes the power users of the power quality and economic evaluation principles, economic costs, economic loss assessment methods, governance programs
Economic assessment methods, assessment processes and assessment indicators.
This section of the assessment of economic losses is limited to direct economic losses caused by power quality problems and power quality problems caused by the number of products less
Indirect economic loss caused by less or forming defective products.
This section applies to electricity users power quality and economic evaluation.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1 Power quality powerquality; qualityofpowersystem
Electrical characteristics of the power system at the designated point, relates to the power supply equipment for normal operation (or operation) of the voltage and current indicators of deviation from the base
The degree of quasi-technical parameters.
Note: The reference specifications generally refer to the value of the indicator under ideal power conditions. These parameters may relate to the compatibility between supply and load.
[GB/T 32507-2016, Definition 2.1.1]
2.2 Voltage dips voltagedip (sag)
The root mean square value of power frequency voltage suddenly drops to 0.1pu ~ 0.9pu in power system, and after 10ms ~ 1min
Return to normal phenomenon.
Note: The IEC standard is reduced to the range of 0.01pu ~ 0.9pu.
[GB/T 30137-2013, Definition 3.1]
2.3 Shortinterruption of short interruptions
The root mean square value of power frequency voltage at a certain point in the power system suddenly drops below 0.1pu and resumes after a brief period of 10ms ~ 1min normal phenomenon.
[GB/T 30137-2013, Definition 3.2]
2.4 Harmonic (component) harmonic
The non-sinusoidal periodic Fourier series decomposition, the frequency of the fundamental frequency is an integer multiple of the sine component.
[GB/T 32507-2016, Definition 2.6.7]
2.5 Interharmonic (component)
The periodic exchange of Fourier series decomposition, the frequency is not equal to an integral multiple of the fundamental frequency component.
[GB/T 24337-1993, Definition 3.6]
