Noja Power has released its Dual Supply GMK. Designed to maximise renewable energy generation asset uptime, this new device provides renewable operators with an option to increase their commercial viability and ROI performance under generation restraint or equipment failure. It allows solar and renewable installation operators to split their generation capacity among two supply incomers, providing a staged mitigation to load shedding or asset maintenance.
At its core, the device is essentially two grid connections in a cubicle. It has two OSM recloser solid dielectric insulated vacuum interrupting circuit breakers, supplied complete with the company’s RC control system. This topology provides all protection, control and automation required for renewable connections, including Rate of Change of Frequency (ROCOF) and Voltage Vector Shift (VVS) protection. Additional options such as revenue metering can be incorporated in the customisation of the equipment, allowing for a fully customised solution to be factory tested, shipped and delivered complete to site.
These two reclosers provide the protection and point of connection to the grid, with the reclosers’ outgoing busbars connected and unified to a single outgoing cable connection.
In the event of requested load shedding, the operator has the option to isolate only part of the installation, reducing the generation in accordance with the split between the incoming feeders. Furthermore, maintenance outages which traditionally implied zero generation can be mitigated, as the outages lead only to partial generation reduction. The section under fault or maintenance can simply be isolated, while the remainder of the installation remains in service.
