An increase in complexity of relays and power systems makes the relay settings and the process of coordination quite difficult. The changes of operating conditions in power systems also adversely affect the installed relays. There is a strong requirement to avoid protection relay maloperation and to ensure continuing optimal relay coordination and operation. It is rather difficult to determine which of the protective relays will operate as specified or whether the coordination of the relays is maintained due to complexity of the system. This paper introduces a reliable and secure interactive framework system for investigation, calculation of relay settings and relay coordination using wavelet based techniques. The interactive system allows an engineer in the control room to assign the location, the type of fault and the relay data set pattern; then the operating time of the protective devices is generated. The system framework introduces a dynamic, interactive transient of the relay models for the power system. © 2007 IEEE.
