Parallel generator set controller MC 200 Neptune

DNVfor marine applications

DNV certification and high reliability MC200Neptune is the latest shore connection controller of SICES with the DNV certification based on the already successful mains supervising controller of MC200, with enhanced coating and sealing to resist harsh marine environment, which justifies in 5 years of warranty. Shore connection control MC200Neptune is managing shore connection of a ship during harbor operation. It’s been designed to synchronize all gensets simultaneously (controlled by GC600Neptune genset controllers) to the mains, with the soft transfer of the loads from the gensets to the mains, avoiding any blackout on the loads during the short time in parallel operation. A ship usually uses the mains power supply only, without gensets long time in parallel, during the shore connection. MC200Neptune automatically or manually controls the shore connection by Mains Circuit Breaker (MCB) and a connection of the bus to the load by Master Generator Circuit Breaker (MGCB). MC200 Neptune includes > The centralization of the start/stop commands towards the generators > An internal synchronizer with voltage, frequency and phase differences control > The centralized management of active power setpoints for the generators, to allow the gradual transfer of the loads with a rate > The centralized management of power factor setpoints for the generators, when operating in shore connection > The loss of mains protections (interface protections), to isolate the generators from the mains in case of failure of the mains itself
