1.2-MVA-SOLAR-STATION (Concrete)

Container with DC-distribu on, Inverters,Medium-Voltage Transformer and Switchgear

The solar sta on HSC1200C is a new development for large photovoltaic power plants. The concrete container includes the DC-distribu on, the inverter, the medium voltage transformer and the medium voltage switchgear. The HSC1200C is a plug and play solu on for quick installa on with low total costs. The HSC1200C is a completely factory-assembled systemonly the DC-connec ons to the photovoltaic array and the AC-connec on to the medium-voltage grid have to be done on site.The photovoltaic array is linked via fuses or circuit breakers and an EMC-fi lter to the input of the inverter. As an op on, the current in each string can be measured separately.The inverter system consists of two iden cal inverters. These inverters operate independently and feed their output power into di erent low-voltage windings of a special medium voltage transformer T1 (please refer to the block diagram below), op mized for the photovoltaic array. The container is connected to the grid via the internal medium-voltage switchgear. Op onally, the auxiliaries of the inverter system and the hea ng can be fed by transformer T2 or from an external source.Each inverter is supplied with all necessary control systems and has its own maximum-power-point tracker. As standard, a PC-based monitoring system with an Ethernet interface provides all important informa on to the user. In the unlikely case of malfunc on, a failure message is generated and sent automa cally. Op onally the communica on can be real-ized via GSM modem.
