Event analysis in primary substation

Abstract

The target of the project is to develop a system which observes the functions of a protection system by using modern microprocessor based relays. Microprocessor based relays have three essential capabilities: the first is the communication with the SRIO and the SCADA system, the second is the internal clock, which is used to produce time stamped event data, and the third is the capability to register some values during the fault. For example, during a short circuit fault the relay registers the value of the short circuit current and information on the number of faulted phases. In the case of an earth fault the relay stores both the neutral current and the neutral voltage
