Implementation of SCADA in a distribution system with a medium voltage motor as load

With the growth of the industry and the need for higher capacity motors, the need arises to implement monitoring, control and protection systems called SCADA in distribution networks. A protection adjustment methodology is proposed and its implementation in a SCADA with IEC61850 communication between five IEDs. GOOSE, MMS and SV messaging was implemented between the IEDs of the network. The system includes a subtransmission network, a distribution network and a dynamic load of a medium voltage motor. The methodology is validated by injecting fault and steady-state voltages and currents using the OMICRON CMC356 equipment. Communication times, response times of protection functions and tripping of the circuit breaker are verified.
