A method automatically parameterizes bay controllers and/or protective devices of a switching arrangement. The method includes automatically detecting the topology of the switching arrangement on the basis of topology information, and automatically determining interlocking and/or enabling conditions for at least one device on the basis of the topology. Communication connections for the at least one device are automatically specified while taking into account the interlocking and/or enabling conditions determined for this device. The at least one device is parameterized with the interlocking and/or enabling conditions and the communication connections and the topology determined for this device, so that interlocking or enabling of a switching action in the at least one device is controllable during the operation of the switching arrangement.

The invention relates to a power supply unit for the provision of at least one switchable power output, having at least one power input U.sub.IN, at least one voltage measuring device that monitors the voltage at the at least one power input U.sub.IN, wherein, if the input voltage falls below a defined threshold U.sub.thres or if the change in the input voltage U.sub.IN per unit of time rises above a defined threshold U.sub.thres/t, the power output/power outputs is/are switched off and the input voltage is then measured at a first timepoint t.sub.1, and, after a first predetermined time (t.sub.d1) (S240), the input voltage U is measured again at a second timepoint t.sub.2, and if the input voltage at the second timepoint is greater than the input voltage at the first timepoint, it is assumed that a short circuit is present at at least one power output.

A power generation and control system is easily installed in a consumer household, a business, or and end-user establishment for generating power and preventing power from flowing to a power grid from a consumer circuit during a power outage. A communications transceiver is adapted to transmit an enabling signal for enabling power generation only after the control system has been installed. The control system can be adapted to replace an existing circuit breaker in a household circuit box and prevents power from traveling from consumer power generators to the grid during a power outage. In the same manner that end-users can add appliances to existing circuits, end-users can easily add additional power generation devices without hiring a professional electrician and without worrying about causing harm to utility workman during power outages.
