Abstract

The application of a microprocessor technique can provide an accurate and reliable means for inserting and disconnecting of the DBR (dynamic braking resistor). This technique is based on the realization of the critical clearing time for the particular power system involved. Such a technique can provide the means to assess stability conditions by implementing the method of the rate of change of kinetic energy (RKE). The scheme gives a prototype approach for utilizing an 8-b Intel 8085 microprocessor for the initiation of switching `in´ and `out´ of the DBR
