Abstract: A method for logging a user into a device for a power generation plant, using a service gateway, wherein an access authorization of the user for the device is stored on the service gateway, is disclosed. The method includes authenticating the user on the service gateway, sending a device access request using an access device from the user to the service gateway specifying an identifier of the device for the power generation plant, and comparing a device secret stored on the service gateway with a copy of the device secret generated using the device secret and stored on the device, via an SRP protocol.

Abstract: A method of communication of distributed devices handling electric energy with communication partners via the Internet includes programming rules in a server. The rules determine between which device and which communication partner a communication connection is to be mediated based on generic properties of the devices, generic properties of the communication partners and an initializing time-variable datum. The communication connection is a point to point, point to multi point or multi point to multi point connection via the internet. Data are transmitted from each device and each communication partner to the server via the Internet. These data include both a communication address and attributes indicative of the generic properties of the device or the communication partner, respectively. The communication connection is mediated between the device and the communication partner determined by the rules in response to a value of the initializing time-variable datum also defined by the rules.

Abstract: The disclosure relates to a method for setting a power class of an inverter, wherein the inverter has a device type plate containing information about the inverter which is device-specific and independent of the selected power class, and wherein the inverter has a class plate which is selected from a plurality of power class-specific class plates each assigned to one power class from a plurality of power classes and contains information about the assigned power class. The method includes capturing an image of the device type plate and the class plate and reading out the device-specific information and the information about the assigned power class from the data captured as an image,—transferring a setting sequence to the inverter, wherein the setting sequence has the information about the assigned power class,—setting the power class of the inverter using the setting sequence following authentication of the read-out information. The disclosure also relates to an inverter having a power class that can be set.

Abstract: A method of detecting a serial arc fault in a DC-power circuit includes injecting an RF-signal with a narrow band-width into the DC-power circuit and measuring a response signal related to the injected RF-signal in the DC-power circuit. The method further includes determining a time derivative of the response signal, analyzing the time derivative, and signaling an occurrence of a serial arc fault in the power circuit based on the results of the analysis. A system for detecting an arc fault is configured to perform a method as described before.

Abstract: To operate electrical devices, power consumptions of all the electrical devices are continually captured and assigned to the individual electrical devices and at least one desired result is achieved by virtue of at least a first control instance of the electrical devices, the operation of which helps to achieve a desired result, and a second control instance of the electrical devices, the operation of which likewise helps to achieve the desired result. The devices are operated in a coordinated fashion. To this end, measured values from multiple measured value transmitters are captured by operating the multiple electrical devices. Correlations between changes in the measured values of the individual measured value transmitters over time and changes in the power consumptions of the individual electrical devices over time are determined and the desired result is selected from a subgroup of results.

Abstract: A method for defining authentication data of a user at an energy conversion device connected to a grid and a source via a network connection includes receiving at the energy conversion device, via the network connection, a request from the user to newly assign authentication data, receiving at the energy conversion device desired authentication data of the user via the network connection, and storing the desired authentication data in the energy conversion device for an authentication of the user in the event of subsequent attempts to access the energy conversion device, when the energy conversion device is disconnected from the connected grid within a first predefined time window after receiving the request.
