T/CPSS 1004-2019 Intelligent substation power quality measurement method

Scope

Scope: This standard specifies the measurement methods, measurement errors, and measurement ranges for power quality indicators such as the frequency of digital signals output by the substation's consolidated units, voltage and current amplitudes, voltage deviations, flicker, voltage sags, short-term interruptions and surges, harmonics, interharmonics, and unbalance. This standard applies to the measurement of power quality parameters of digital signals sampled synchronously at intervals in smart substations. The measurement of other power quality parameters of digital signals sampled synchronously at intervals can also be used for reference. Main technical content: This standard proposes technical requirements for consolidated units to meet power quality measurement requirements, standardizes the methods for various power quality measurements of digital signals output by consolidated units, and provides theoretical and technical guidance for power quality testing in smart substations. Other relevant national standards, industry standards, enterprise standards, and international standards do not cover the related content of this standard.
