Air Core Reactors for Power Quality and FACTS

Trench is a recognized world leader in the design and manufacture of dry type air-core reactors. Since decades Trench is supplying air-core reactor for Power Quality and FACTS applications to utility and industry customers worldwide.

The increased in-feed of renewable energy creates new challenges for the balance and stability of electrial grids worldwide. More and more utility customers invest into power quality and FACTS system and value Trench air-core reactors as a core components for these applications.

Flexible AC Transmission Systems (FACTS) increase the reliability of AC grids and reduce the delivery costs. They improve quality and efficienc of power transmission by supplying inductive and capacitive reactive power to the grid. Trench’s air-core reactors help customers to achieve these targets by a proven design that is customized to every individual design.

Reactors for Power Quality and FACTS include: Reactors for filter circuits, Reactors for capacitor banks, Reactors for SVCs and STATCOMS

Main Features

Reactors for FACTS
Flexible AC Transmission Systems (FACTS) increase the reliability of AC grids and reduce power delivery costs. They improve quality and efficiency of power transmission by supplying inductive and capacitive reactive power to the grid. Depending in tne technology of the FACTS device different types of reactors are used. e.g.:

FOR CONVENTIONAL STATIC VAR SYSTEMS (SVCs):

  • Thyristor-controlled shunt reactors (TCR). The compensating power is changed by controlling the current through the reactor by means of the thyristor valves.
  • Thyristor-switched capacitor reactors (TSC)
  • Filter reactors

FOR STATIC SYNCHRONOUS COMPENSATORS USING IGBT VALVES (VSC) FOR POWER CONTROL:

  • Line/phase reactors

FOR MSC(DN) CIRCUITS:

  • Filter reactors
  • Damping Reactor

FOR SC:

  • Damping reactors

FOR TCSC:

  • Thyristor-controlled parallel reactor

THYRISTOR CONTROLLED SHUNT REACTORS

Thyristor Controlled Shunt Reactors (TCR) are extensively used in static VAR systems in which reactive VARs are adjusted by thyristor circuits. Static VAR compensator reactor applications normally include:

  • Thyristor controlled shunt reactors (TCR): The compensating power is changed by controlling the current through the reactor by means of the thyristor valves.
  • Thyristor-switched reactors (TSR)
  • Thyristor switched capacitor reactors (TSC)
  • Filter reactors (FR)
