T/CES 012-2018 Power quality monitoring device testing specification

Scope

Scope: This standard specifies the inspection rules, inspection conditions, and inspection methods for power quality monitoring devices in traditional and smart substations in terms of basic functions, communication functions, electrical performance, safety performance, climate environment, and electromagnetic compatibility performance. This standard applies to power quality monitoring devices used in traditional and smart substations; Main technical content: With the rapid development of automation technology, increasing electricity consumption, and an increasing number of grid users, the use of sensitive equipment and non-linear power electronic devices has led to an increasing focus on power quality issues such as voltage deviation, imbalance, harmonics, fluctuations, flicker, and voltage sags in the power grid. Therefore, more and more power quality monitoring devices are being applied in the field of power quality monitoring. At the same time, with the development of technology and the increasing demand for quality of life, traditional substations have been unable to fully meet people's requirements for safety, reliability, and economy. Smart substations are gradually being promoted across the country, and the use of power quality monitoring devices in smart substations is also increasing. However, there are currently no standardized detection technologies for power quality monitoring devices in smart substations in China. Therefore, this standard, based on the detection technologies for traditional power quality monitoring devices, innovatively and appropriately introduces the detection technologies for power quality monitoring devices in smart substations, which can further guide the development and application of power quality monitoring products in traditional and smart substations and is of great significance for building a technically advanced and safe and reliable modern distribution network. This standard is based on the national standard "General Requi
