Agenda • Background on Simulated IEC 61850 Systems • Examples: ü RTU/Gateway Mapping Test ü HMI Verification ü PLC Testing
Background on Simulated IEC 61850 Systems SCD File RTU/Gateway Simulation Includes: • Communications • IED Data Models • Control Blocks • Simulated Logic HMI Station Bus Simulated IEDs Process Bus Primary Equipment
Why Test With Simulated Systems? Reduce Costs by Testing Earlier • Discover configuration issues earlier in the engineering process • Reduced costs by testing before acceptance testing or commissioning Accelerate Testing Process • Test before all equipment is setup and configured • Easily change test configurations Reduce Time with Automated Testing • Automate tests that require lots of repeatable steps • Increase test coverage with repeatable and well documented tests
RTU and Gateway Testing SCADA System Testing Coverage RTU/Gateway Configuration • Control Mapping • Report Mapping • Value, Time, Quality Simulated Master RTU/Gateway Device Under Test IEC 61850 Simulated IEDs SCD File Data Sets STAT MEAS TRK STAT MEAS PROT STAT MEAS TRK STAT MEAS CILO STAT RBRF TRK

HMI Testing Coverage HMI Configuration • Controls • Alarms/Events • Measurements SCD File Tests HMI Device Under Test Simulated IEDs Test Cases Alarm Events Statuses Measurements Control Requests
HMI Example Operator HMI Controls Record Results Simulated IEDs Step Through Test Cases Results Reports 1) Transformer Alarm 2) Distance Fault 3) Breaker Control Test Case Objects Tested Test Values 1) Alarm Event MMXU.
