Cost Effective Power Transfer

GE’s Series Compensation System allows utilities to cost effectively increase power transfer capabilities of their existing infrastructure and new transmission lines.

Series compensation systems are installed in series with the High Voltage transmission line, and consist of an integrated, custom-designed system with many power capacitors arranged in series and parallel. The most critical equipment is the parallel protective system that prevents damage to the capacitors during power system faults.  

GE also offers an extensive portfolio of project management and engineering services, physical equipment and installation services, which results in an integrated and robust system for customers.

Overview

Today’s transmission system is becoming increasingly complex and is expected to carry bulk power in ways it was never designed for. The expectation is that transmission requirements will only increase, as power generation sources continue to evolve.

Series Compensation System Components

GE’s Series Compensation System is comprised with industry leading and patented technology, helping customers achieve high reliability and lowest possible losses on their transmission lines. The major components of the Series Compensation System include Capacitors, Metal Oxide Varistors, Triggered Air Gap, and Fast By-Pass Switches.


  Capacitors

Capacitors

The capacitors are placed in series on a transmission circuit intended to reduce the overall line impedance and offers improved load division on parallel circuits, system transient and steady state system stability and allows for increased power transfer capability.

  Modular Arc Commutating Triggered Air Gap

Modular Arc Commutating Triggered Air Gap (MACTAG)

A MACTAG is often used as an intermediate bypass device and is faster than the bypass switch, but not instantaneous like the Metal Oxide Varistor (MOV). GE’s patented design uses plasma injection to establish an arc which bypasses the capacitors and MOV until the bypass switch can close. GE’s MACTAG is the fastest in the industry (< 0.3 ms) as it does not rely on ground-based controls to initiate a bypass. A MACTAG lowers MOV cost by reducing the required MOV energy absorption.

  Metal Oxide Varistor

Metal Oxide Varistor (MOV)

MOV are the primary device that protects the capacitors from overvoltage by diverting fault current. The MOV are semiconductors that conduct above a specific voltage, known as the Protective Level Voltage. The MOV limits the voltage across the capacitor bank to a safe value for the capacitors handling very high current for short periods of time and protect the capacitors until another bypass path is established.

  Fast By-Pass Switch

Fast By-Pass (Priority Close) Switch

The Fast By-Pass Switch closes rapidly to limit both MOV and TAG energy, removing the series capacitors from service. This switch is also used for normal switching to insert the series capacitors or bypass them.

Capacitor Options

GE’s Series Compensation offerings include three capacitor options: fuseless, internally fused or externally fused. GE works with customers to evaluate their requirements and determine the best technical solution to meet customer needs to ensure, reliable and cost effective system.


Fuseless Design
    Fuseless Design
  • Lowest losses, typically < 0.12 watts/kvar
  • High reliability: A lower internal element voltage stress rise for the same number of internal failures in comparison to an internally fused option
  • A higher unbalanced current for the same internal element voltage stress
  • Fault tolerance with continued operation even with failed rolls
  • GE recommended option
  Internally Fused Design
    Internally Fused Design
  • Losses typically > 0.15 watts/kvar
  • One fuse per internal roll. Each roll is protected by an internal fuse element
  • The fuse allows a roll to fail as an open circuit
  • There are multiple rolls in parallel. This places a very small incremental stress on adjacent rolls when a fuse operates. This helps prevent a cascading failure within an individual can
  Externally Fused Design
    Externally Fused Design
  • One fuse per capacitor unit. Fewer connections mean fewer points of failure
  • Facilitates easy identification of a failed unit as the blown fuse is obvious
  • Once the standard, now limited specialty applications
GE's Fuseless Design

GE recommends the fuseless option, which has been the dominant technology since the late 1990’s and is proven with a long term field failure rate of less than 0.03% per year. The film foil capacitor is a proven GE design that has been in use since the 1970s. The fuseless design produces the highest unbalance current (easy to detect a failed roll) with the lowest voltage stress on the remaining units (lower chance for a cascading failure). The diagram below depicts the two capacitor groups.
