Power Quality and Economic Evaluation

Part 2. Economic evaluation of public distribution networks

1 Scope

This part of the standard specification of public power distribution network power quality and economic evaluation methods, given the typical power quality problems caused by public distribution

Network economic loss assessment methods and distribution network operators main power quality control program economic evaluation methods.

This section applies to the public distribution network in the economic evaluation of power quality problems. Other power plants and other distribution network with reference to the implementation.

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 Sag voltageag (voltagedig)

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) harmoniccomponent

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 component.

[GB/T 24337-1993, Definition 3.6]

2.6 Voltage fluctuation voltagefluctuation

Voltage rms (rms) A series of changes or continuous changes.

[GB/T 12326-2008, Definition 3.3]
