Connecting Wind Farms to the Distribution Grid using Reclosers

Practical Application Demonstrated in the Philippines

Evolution in switchgear technology has simplified renewable connection as demonstrated by a new Wind Farm in the Philippines connected to the grid using a NOJA Power OSM Recloser. This installation at Romblon in early 2019 forms part of local initiatives for sustainable energy development.

Providing Auto-Synchronisation, Synchrocheck and conventional protection functions, the OSM Recloser was selected as the connection switchgear to address all challenges of renewable connection.

NOJA Power’s OSM Recloser system has been deployed in multiple renewable and distributed generation connection projects, including Solar and reclaimed gas power stations. For applications that require only protection and control, the Pole mounted OSM Recloser system provides a cost-effective complete solution. If metering or differential protection is required, the NOJA Power GMK provides a complete assembled solution including an OSM Recloser with all auxiliary control and metering capabilities incorporated in a single mobile ground mount platform.

Renewable connection applications typically require sensing on both sides of the open connection to facilitate synchronised connection of the renewable asset to the network. NOJA Power’s OSM Recloser provides this feature as standard, allowing for an off-the-shelf product to address complex connection requirements. NOJA Power’s OSM Recloser is a comprehensive system, comprised of the primary switchgear and secondary RC10 Control System. The RC10 provides all protection, automation and communications features typically required in renewable applications, simplifying commissioning and minimising installation capital expenditure.

“As our customers increase their focus on a sustainable future, renewable energy connections to the distribution grid are becoming more and more common globally,” says NOJA Power Group Managing Director Neil O’Sullivan. “NOJA Power has engineered out of the box solutions to simplify the connection of large-scale renewable energy to the distribution grid.”

The President and CEO of PESIN Jojo Conde added, “Power Equipment & Supplies has been supplying NOJA Power reclosers in the Philippines for almost 2 decades. The applications have evolved from simple distribution circuit breakers to fully integrated remote controlled smart grid solutions with the latest applications being to connect large scale renewable energy to the distribution grid.”
