Description: Das Projekt "KWP 250 PV power plants for direct injection in light train low voltage DC networks" wird vom Umweltbundesamt gefördert und von üstra Hannoversche Verkehrsbetriebe AG durchgeführt. Objective: Public transportation low voltage networks are particularly well suited for direct connection of PV systems because of their electrical characteristics and since the load of the network coincides with the PV production. So, very simple and therefore reliable PV power stations can be build to inject the solar production in such networks. The purpose of this project is to manufacture and install such PV power plants in Germany (Hannover) and in Switzerland (Geneva and Lausanne). General Information: The PV modules are connected in large series to reach a sufficient nominal voltage to feed the network through the diodes. The number of modules to be used in each series will be determined during the first phase of the project according the network voltage characteristics and the weather conditions. The PV modules to be used will be determined on invitation to tender with the conditions of high voltage certification. Antilightening protection will be added along with a general manual switch to disconnect totally the plants from the network. A network voltage control will be added, disconnecting the PV modules in case the voltage reaches the high voltage or low voltage boundaries. A data logger, will be installed on each power plant to monitor the following network voltage, PV currents, sun radiance, temperature and connection state of the plant to the network. TECHNICAL INNOVATIONS Direct connection of the series of modules to the low voltage network. Incite the manufacturer of PV modules to certify their modules for a high voltage usage. Test of a maximum power point tracking dc-dc converter. Prime Contractor: Uestra Hannoversche Verkehrsbetriebe AG; Hannover; Germany.
