Guide for the Functional Specification of Medium Voltage (1–35 kV) Electronic Series Devices for Compensation of Voltage Fluctuations
|Publication Date:||12 September 2002|
This guide provides general guidelines for the preparation of a functional specification for solid-state electronic series devices used mainly for compensation of voltage fluctuation. The guide covers devices rated to medium voltage (1-35 kV). In general, these devices contain: an inverter, a rectifier or dc-to-dc converter, an energy storage device, injection transformers connected in series with the load, and a normally open by-pass switch.
In order to interface these devices with the load, additional equipment should be provided including current and potential transformers, bypass and isolation breakers, fast acting solid-state bypass switch, and threephase low-voltage service for auxiliary power
This guide includes technical clauses describing the user's requirements, including operation methods and environmental conditions. It specifies basic requirements of solid-state electronic devices used for compensation of voltage fluctuations. In addition, the guide covers the required installation and start-up services.
