Abstract

In order to simplify and design the configuration in particular of a power automation installation with a comparatively high number of power automation devices in such a way that as far as possible no interruption of operation is necessary, a method for operating a power automation installation is proposed, wherein the power automation installation includes a plurality of power automation devices and at least one higher-level installation control device for controlling and/or monitoring the power automation devices. An additional power automation device is connected to the concentrator device and automatic configuration of the concentrator device is carried out by the incorporation of a device description file of the additional power automation device into a concentrator data model of the concentrator device. There is also provided a corresponding power automation installation.

Claims

1-9. -9. (canceled)

10. A method of operating a power automation installation, the power automation installation having:

a plurality of power automation devices and at least one higher-level installation control device for controlling and/or monitoring the power automation devices, wherein the power automation devices are connected to the installation control device by a concentrator device and a data model file containing a concentrator data model is stored in a memory of the concentrator device and wherein the concentrator data model contains information about the power automation devices connected to the concentrator device, their functions and settings, and also provides data objects the states of which are adapted to current states of corresponding data objects of the power automation devices, and

the method comprising the following steps;

connecting an additional power automation device to the concentrator device;

generating a communication address for the additional power automation device by the concentrator device and transmitting the communication address to the additional power automation device;

storing the communication address in the additional power automation device and using the communication address for further communication with the concentrator device;

retrieving a device description file of the power automation device by the concentrator device, the device description file specifying functions and settings of the additional power automation device;

adapting the concentrator data model to the functions and settings of the additional power automation device specified by the device description file; and

providing the adapted concentrator data model for the installation control device.

11. The method according to claim 10, which comprises:

recording, by the installation control device, a user input prior to connecting the additional power automation device to the concentrator device, the user input specifying a device code of the additional power automation device;

after connection of the additional power automation device to the concentrator device, transmitting from the additional power automation device a device code thereof to the concentrator device;

sending with the concentrator device the device code transmitted by the additional power automation device to the installation control device;

checking, by the installation control device, whether the device code transmitted by the concentrator device matches the device code entered by the user and, in the case of a matching device code, sending a confirmation telegram to the concentrator device; and

subsequently retrieving, by the concentrator device, the device description file from the additional power automation device only after the confirmation telegram is on hand.

12. The method according to claim 10, wherein:

the installation control device comprises an installation data model file containing an installation data model, the installation data model providing information about all power automation devices of the power automation installation whose functions and settings comprise as well as provide data objects, whose states are adapted to the current states of corresponding data objects of the power automation devices;

the installation control device adapts the installation data model thereof to the functions and settings of the additional power automation device specified by the concentrator data model; and

in the operation of the power automation installation, a change of state of a data object of a power automation device connected to the concentrator device brings about a corresponding change of the states of the corresponding data objects of the concentrator data model and of the installation data model.

13. The method according to claim 12, which comprises:

first checking with the installation control device the information contained in the concentrator data model about functions and settings of the additional power automation device to determine whether the functions and settings are compatible with the installation data model;

adapting with the installation control device the installation data model to the concentrator data model and sending an activation telegram to the concentrator device only in the event of existing compatibility; and

integrating the additional power automation device in the operation of the power automation installation only if an activation telegram has been received.

14. The method according to claim 10, which comprises:

on occasion of a removal of a power automation device from the power automation installation, detecting by the concentrator device a missing connection to the removed power automation device and adapting the concentrator data model by deleting entries for the removed power automation device and transmitting an adapted concentrator data model to the installation control device; and

adapting an installation data model of installation control device by deleting the entries for the removed power automation device.

15. The method according to claim 10, wherein the device description file of the power automation device and of the additional power automation device is specified in the form of an ICD file or IID file in accordance with the IEC 61850 standard.

16. The method according to claim 10, wherein the concentrator data model of the concentrator device is specified in the form of an SCD file in accordance with the IEC 61850 standard.

17. The method according to claim 12, wherein the installation data model of the installation control device is specified in the form of an SCD file in accordance with the IEC 61850 standard.

18. A power automation installation, comprising:

a plurality of power automation devices and at least one installation control device for controlling and/or monitoring the power automation devices;

a concentrator device connecting said power automation devices with said installation control device;

wherein said at least one installation control device and said concentrator device of the power automation installation are configured for carrying out the method according to claim 10.
