摘要:
The invention relates inter alia to a method for protecting, controlling or monitoring an electrical switchgear or power supply station (10). According to said method, a field device (20), especially a protective device, is used to generate data telegrams (D) that relate to the status of the switchgear or power supply station, and the data telegrams are transmitted to a higher-order command level device (40). According to the invention, a second field device (30) is redundant with respect to the first field device and is used to check whether the first field device (20) is operative by operating a communication link (60) between the two field devices via which link the second field device is informed of the functional status of the first field device. The second field device ceases forwarding own data telegrams (D) to the higher-order command level device if the first field device is operative, else it transmits data telegrams relating to the status of the switchgear or power supply station to the higher-order command level device.

In order to simplify and design the configuration in particular of a power automation installation (10) with a comparatively high number of power automation devices (13a-c) in such a way that as far as possible no interruption of operation is necessary, a method for operating a power automation installation (10) is proposed, wherein the power automation installation (10) comprises a plurality of power automation devices (13a-c) and at least one higher-level installation control device (11) for controlling and/or monitoring the power automation devices (13a-c). An additional power automation device (13d) is connected to the concentrator device (12) and automatic configuration of the concentrator device (12) is carried out by the incorporation of a device description file of the additional power automation device (13d) into a concentrator data model of the concentrator device (12). The invention also relates to a corresponding power automation installation (10).

The invention relates, inter alia, to a method for operating an arrangement (10) which is suitable for protecting, controlling and/or monitoring an electrical switchgear or energy supply system and comprises: a central control unit (20), at least one terminal (E1-E4) which is suitable for measuring energy, switching energy and/or transmitting status data relating to an energy source connected to the terminal or an energy consumer connected to the terminal, and a communication network (30). According to the invention, the central control unit allocates network configuration data (D) to the terminal after the terminal has been connected to the communication network, for the terminal to transmit the type identifier (T4) thereof to the central control unit using the allocated network configuration data and for the function-related communication between the terminal and the central control unit to be operated using a terminal type description (G (E4) ) which corresponds to the type identifier.
摘要:
The invention relates amongst other things to a method for configuring an arrangement (10) comprising a command level device (20) and at least one arrangement (10) comprising a field device connected to the command level device, for protecting controlling or monitoring an electrical switch or power supply gear, wherein a command level configuration file (SCD) describing the configuration of the arrangement is generated. According to the invention, after replacement of the field device (IED_alt) by a new field device (IED_neu), a new command level configuration file (SCD' ) is generated to replace the old command level configuration file, taking account of the properties of the new field device and a new field device parameter data set is generated with the new command level configuration file, by means of which the new field device is parameterised, telegramme configuration files being extracted from the old command level configuration file, describing the data telegramme generation of the old field device and the new command level configuration file and the new field device parameter data set are generated with said telegramme configuration data such that the new field device generates data telegrammes with a data telegramme addressing matching that of the old field device.
