Solar and wind power can be used to feed into a public power grid (grid-connected operation) or for local consumption (stand-alone operation). Modern energy systems combine both options, being controlled according to demand and availability. Storage systems and energy management systems are used to control the energy flows. The solar and wind power generated can be used to produce green hydrogen by electrolysis, for example.
ET 255 contains networked components of an energy system as well as an energy management system (EMS). Data from the networked components are recorded in the central communication and control unit (CCU).
Either the ET 255.01 photovoltaic simulator or real photovoltaic modules, such as ET 255.02, can be used as the solar electricity source. With ET 255.04, a wind power plant is available as an additional renewable energy source. The optional accessory ET 255.03 contains two controllable electrical consumers that are prioritized differently when supplied by ET 255. Alternatively, the ET 280 electrolyser can be integrated into the system as a consumer. Used in conjunction with the accessories, the behaviour of an energy system can be investigated under varying operating conditions.
In order to ensure there is sufficient illuminance, the trainer should be operated with sunlight or the optionally available artificial light source HL 313.01.
Operating data from the solar electricity system is displayed on a touch screen. It is also possible to retrieve operating data via the manufacturer’s web portal.
The trainer is controlled via the GUNT software on an external PC (not included), which is connected via a network interface. Typical generation and consumption profiles can be specified via time-controlled sequences. The network-capable software makes it possible to follow and analyse the experiments at any number of workstations via a LAN/WLAN connection to the local network.
