The first of three UK STATCOM substations is energized with GE’s latest grid technology.

GE Renewable Energy’s Grid Solutions business has left a mark on the world with the stimulation of the Bolney substation — the first of three substations to be a piece of the biggest STATCOM plot in Europe, possessed by UK utility National Grid. The Bolney substation underpins the huge populace and burden focuses south of London, just as high-voltage direct current (HVDC) interconnectors with Europe.

In 2016, GE’s Grid Solutions was granted an agreement by National Grid to supply its most recent utility-grade static synchronous compensator (STATCOM) arrangement along the transmission network at the Bolney, Ninfield, and Richborough substations in southeast UK. The dynamic receptive compensator (DRC) arrangement in business activity at the Bolney substation since May 2019 uses a Modular Multilevel Converter (MMC) STATCOM and thyristor exchanged capacitor (TSC) innovation to furnish responsive power pay alongside a High Voltage Mechanically Switched Capacitor Dynamic Network (MSCDN). This is a first-of-its-sort voltage remuneration plot that will enable National Grid to give a solid power supply to its clients, in any event, when system shortcomings happen.

Verifiably, National Grid has depended on GE to convey cutting edge innovation answers for tackle an unpredictable issue. National Grid recently granted GE the first-ever STATCOM in a business delicate for their East Claydon substation. This undertaking set benchmark “firsts” in territories including: the world’s first business MMC, the first occasion when that a STATCOM was joined with TSC innovation, and the world’s first relocatable STATCOM.

“National Grid has a long and celebrated history with GE and has coordinated on various cutting edge innovation undertakings to fathom network difficulties,” said National Grid’s Electricity Transmission, Head of Customer Solutions Hedd Roberts. “With Bolney, we are currently in a position where we can stimulate the biggest voltage pay conspire in Europe. This is a gigantic accomplishment, and one that I have been pleased to be a piece of.”

With STATCOM innovation set up, the Bolney 400 kV substation is presently supporting National Grid’s exchanging current (AC) arrange and improving local voltage solidness for the UK-Belgium HVDC interconnection, which will convey more than 1 GW of bi-directional power between the two nations. With under 90 millisecond reaction time, the innovation conveys dynamic responsive power go from – 100 Mvar inductive (engrossing vars) to +225 Mvar capacitive (infusing vars) with accessibility of 98% according to client prerequisite.

“While European nations try to improve lattice interconnections, including the arrangement to integrate them with the European Super Grid, they additionally should guarantee that their very own framework stays dependable and practical. The improved system security conveyed by GE’s utility STATCOM arrangement does only that, furnishing clients with the certainty they have to move forward when arranging or incorporating progressively sustainable power source into their lattices. At National Grid’s Bolney substation, this arrangement is as of now attempting to help HVDC interconnection dependability and by and large flexibility to blame events. In addition, it will help bolster the European Union’s methodology of accomplishing an aggressive and coordinated European vitality commercial center,” said Fabrice Jullien, Global FACTS Business Leader for Grid Integration Solutions, GE Renewable Energy’s Grid Solutions business.

This most recent age STATCOM arrangement is a Voltage Source Converter (VSC) innovation dependent on Modular Multilevel Converter (MMC) design utilized from GE’s vigorous power gadgets experience. This plan gives more steady yield control age than other aggressive arrangements, helping client lattices handle blames and issue recuperation that is inside the business’ best execution. This plan, joined with GE’s Advanced Digital Control framework and experience from in excess of 400 shunt associated FACTS arrangements, offers clients a carefully empowered arrangement.
