Here are several training lessons we'll use to teach Overcurrent Protection Basics
Objective 1: Understand basic feeder overcurrent protection. Create relay settings for a distribution feeder relay. Test distribution feeder relays against the relays settings utilizing a relay test set.
Objective 2: Understand coordination of feeder overcurrent protection. Using a team environment, create an overcurrent protection scheme utilizing three feeder relays (simulating one feeder relay and two downstream relays). Apply the relay settings to each relay and test each relay. Connect the relays to the distribution simulator and simulate faults between each of the interrupting devices.
Objective 3: Understand how to download metering and fault data from smart meters and microprocessor based relays. Utilizing the feeder overcurrent protection scheme simulate fault between each of the interrupting devices. Download fault and metering data from each of the relays and meters. Utilizing vendor software plot the relay fault data.
Objective 4: Understand IED communication. Configure communication processors to interrogate relays and meters to obtain switch (breaker, recloser) position, voltages, currents, and fault information. Utilizing the feeder overcurrent protection scheme, simulate fault between each of the interrupting devices. Verify that the communication processor collects appropriate data from relays and meters.
Objective 5: Understand how a distribution automation system can be configured using relays, interrupting devices, meters and communication processors to enhance system reliability and availability. Utilizing the system created in earlier lessons connect communication processors to allow the sharing of information between devices. Program the communication processors to determine the location of faults. Isolate those faults and re-establish power to those segments not containing faults.
