Estimating the term…
A protective device (1) for an electrical power distribution network has: means for processing measured values (14) from measurement appliances (3,4) for the power distribution network, means for initiating switching commands (16) by means of primary appliances (2) for the power distribution network, as well as a programmable protective function which, when it is carried out, determines the switching commands on the basis of the measured values. In this case, the protective device (1) has programmable logic (13), which can be programmed in order to carry out the protective function. A method for installation of a programmable protective function in a protective device (1) for an electrical power distribution network has the following steps: transmission of a description of the protective function in the form of a description of a hardware design via a communication link (5) to the protective device (1), programming of programmable logic (13) in the protective device (1) on the basis of the description of the protective function, and carrying out the protective function by means of the programmable logic (13).
A protective device (1) for an electrical power distribution network, with the protective device (1) having means for processing of measured values (14) from measurement appliances (3, 4) for the power distribution network, means for initiating switching commands (16) by primary appliances (2) for the power distribution network, as well as a programmable protective function which, when it is carried out, determines the switching commands on the basis of the measured values,
The protective device (1) as claimed in one of the preceding claims, with the programmable logic 13 being an FPGA (Field Programmable Gate Array) or a CPLD (Complex Programmable Logic Device).
A method for installation of a protective function in a protective device (1) for an electrical power distribution network, wherein the protective device (1) has means for processing (14) measured values from measurement appliances (3, 4) for the power distribution network, and means for initiating (16) switching commands by primary appliances (2) for the power distribution network, and the protective function, when it is carried out, determines the switching commands on the basis of the measured values,
