MECCALTE GENSET CONTROLLER RN200
The RN200 is a controller for the protection and control of the invertersused with renewable sources (wind, photovoltaic, etc) in microgrids.It allows for simple integration of renewable sources with generatorsand/or mains. It allows to maximize the penetration of renewablesources, while ensuring maximum safety on the power supply tothe load and maximum efficiency of the generators, while avoidingunderloading of the sets.It communicates via a CANBUS interface with the genset controllers(GC600, DST4602 Evolution) and with the mains controllers (MC200),ensuring simple integration of all components (both from the logicalpoint of view and for the wirings).Each RN200 manages up to maximum 16 inverters (and maximum16 RN200 are managed per system); communicates through theModbus protocol, using any of its communication interfaces (RS232,RS485, Ethernet). The inverters can also be of different types. Fromeach inverter, it acquires the rated and current powers, as well as thediagnostic alarm codes. It is able to start/stop the inverters, as well asto control their active/reactive powers.
Product Introduction:
MAIN FEATURES
• Automatic start/stop of the inverters, according to the presence ofvoltage on the common bus
• Automatic management of a circuit breaker (RNCB), connecting theinverters to the common bars
• Limitation of the active power of the inverters, to ensure theoperation of the generators at a configurable minimum power (toavoid engine wear caused by prolonged operation at low power)
• Setting of a power reserve (SPINNING RESERVE) for the generators,so that they can compensate for sudden drops• in the production of renewable sources (clouds) without causingblackouts on the loads
• Two ways of managing the reactive power of the inverters:
• Fixed power factor on the generators (and all the rest is supplied/absorbed by the inverters)
• Sharing of reactive power with generators, based on nominalpowers• Possibility of working OFF-GRID (island mode) and ON-GRID (inparallel to the grid)
• Percentage sharing of active/reactive powers among inverters
• Percentage sharing of active/reactive powers among the RN200
It also allows manual control of both the inverters and the RNCB circuitbreaker.
The setting of the parameters can be managed directly from the frontpanel of the controller, or from the free BOARDPRG4 programmingsoftware.
A complete and configurable historical recording system is available,which makes ‘on event’ and periodic recordings (maximum 523recordings for each archive with the default configuration). Thehistorical archives can be viewed on the display of the controller or viathe HISVIEW PC software.
The device includes a fully configurable PLC, in addition to the AND/ORlogic that can be combined with timers: in this way it is able to satisfyspecific customer or application requests. The PLCEDITOR softwareallows you to create and test the PLC program.
