Combined power plant
First Claim
1. A combined power plant for feeding energy into a non-local power network, comprising:
- at least one turbine power plant comprising a turbine and a connection to the non-local power network to feed energy in from the turbine power plant to the non-local power network;
at least one energy storage installation comprising one or more energy storage modules; and
a monitoring unit configured to monitor a rotational speed of the turbine, without any need to measure network parameters in the non-local power network, on the basis of a rotational speed-specific characteristic quantity without having to use the control parameters of a network frequency for this purpose, at least while the energy is being fed into the non-local power network,wherein the energy storage installation is connected to the non-local power network separately or via the turbine power plant, andwherein the monitoring unit is connected to a control unit of the appertaining energy storage installation in order to transmit a characteristic quantity signal based on the rotational speed-specific characteristic quantity to the control unit via a data connection, and the control unit of the energy storage installation is configured in such a way that, in response to the characteristic quantity signal, the control unit causes the energy storage installation to feed additional energy into the non-local power network, thereby improving safety against a sudden power failure in the non-local network, based on the rotational speed of the turbines falling, without the energy storage installation having to be connected to a global external network control or to a network agency for the purpose of network-supporting control.

Abstract
A combined power plant is disclosed for feeding energy into a non-local power network. The combined power plant includes at least one turbine power plant and at least one energy storage installation with one or more energy storage modules, whereby the turbine power plant is connected to the non-local power network in order to feed in power. A monitoring unit monitors the rotational speed of a turbine on the basis of a rotational speed-specific characteristic quantity, at least while the energy is being fed into the non-local power network. The energy storage installation is connected to the non-local power network separately or via the turbine power plant, whereby the monitoring unit is connected to a control unit of the appertaining energy storage installation in order to transmit a characteristic quantity signal based on the rotational speed-specific characteristic quantity to the control unit via a data connection.
