ABSTRACT OF THE INVENTION In the method for switching-error-protected operation of the switching devices of a high-voltage switching station, the current operational state of the station is determined from the signals of the position indicating contacts (KI, KII, KIII) of the switching devices. Using the opera- tional state determined, switching operation request com- mands (for example KA) present are checked for release or blocking by means of switching-error-protection inter- locking rules. In the case of changes of the topological configuration of the high-voltage switching station and/or in the case of changes of the switching-error-protection interlocking rules, it should be possible to adapt this method to these changes in a simple manner and without losing operational reliability. This is achieved by decoupling the topological configura- tion of the high-voltage switching station from the switching-error-protection interlocking rules. In this decoupling, the topological configuration of the high- voltage switching station and the switching-error-protec- tion interlocking rules are stored independently of each other. From the current position indicating signals of the switching devices and the topological configuration stored, topological elements establishing the current operational state of the high-voltage switching station are formed by means of which the switching-error-protec- tion interlocking rules are interrogated for release or blocking of the switching operation request commands (KE) present.
