IEEE Std 1623:2020 pdf download.IEEE Guide for the Functional Specification of Medium Voltage(1kV to 35kV) Electronic Shunt Devices for Dynamic Voltage Compensation.
This document provides general guidelines on the preparation of a functional specification for a solid-state electronic shunt device used mainly to compensate for voltage fluctuation. The guide covers devices rated to medium voltage (1 kV to 35 kV). In general. these devices contain: a bidirectional converter, an energy storage device, and a coupling transformer connected in parallel. The guide also covers the following equipment to assure proper interface with the electric network including, but not limited to, voltage and current transformers. disconnect switches, circuit breakers, and three-phase low voltage service for auxiliary power.
Normally these devices are not designed for flicker compensation. If flicker compensation is needed, the specification may be modified and the manufacturer can design the device for flicker compensation.
1.2 Purpose
The purpose of the guide is to provide information to utilities and other users to prepare a specification when they intend to purchase a shunt device.
The guide includes technical clauses describing the user’s requirements, including operation methods and environmental conditions. It specifies basic requirements of solid-state electronic shunt devices used for compensation of voltage fluctuations by injection of reactive power.
1.3 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is recommended that).
The word may is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (cumi equals is able to).
