This document provides general guidelines for the preparation of a functional specification for solid-state electronic shunt devices used mainly for compensation of voltage fluctuation. The guide covers devices rated to medium voltage (1 kV-35 kV). This device contains in general: an inverter, rectifier or DC converter, energy storage device, and coupling transformer. The device typically is connected in parallel with the network using a coupling transformer.

This project provides guidelines for preparation of functional specification for solid state shunt device used to compensate voltage fluctuation. The guide covers devices rated to medium voltage (1-35kV). The device contains in general: an inverter, rectifier or DC converter, energy storage device, coupling transformer connected in parallel. In addition, additional equipment should be provided to assure proper interface with the electric network. The additional equipment includes: voltage and current transformers, disconnect switches, circuit breakers and three phase low voltage service for auxiliary power.

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 Medium Voltage (1kV-35kV) Electronic Shunt Devices For Dynamic Voltage Compensation are new devices and utility engineers are not familiar with their requirements.
