Benefits

• Improve understanding of protective relaying concepts and applications
• Test protections under realistic and challenging fault conditions
• Easily set up and execute realistic, simple or complex tests based on actual power system parameters
• Easily create test cases for and perform end-to-end line protection testing
• Monitor values of complex relaying quantities during testing
• See power system quantities in primary or per unit values while testing using secondary values

This supercharged visual power system modelling program allows you to:

• Calculate real-world AC load and fault quantities based on standard power system models (radial, radial with load, 2-terminal, 3-terminal, 2-terminal with tapped load, parallel line, etc) with minimum effort and understanding. (The radial model alone, is a full graphical replacement for the SEL Onebus program.)
• Graphically visualize the impedance, power, sequence components measured by a device.
• Test the REAL dynamic performance of a device against calculated fault conditions based on actual power system parameters.
• Compare the actual to theoretical performance of a protection element
• Easily create test cases for end-to-end testing based on actual power system parameters.
• Create IEEE COMTRADE file format test waveforms for playback or end-to-end testing
• Visualize and learn about power system phenomena such as power swings, load encroachment, remote infeed and mutual coupling from built in examples with walk through explanations.
• Visualize and test the expanded and dynamic characteristics of impedance elements.
• Visualize and test the action of complex impedance and directional elements that use zero sequence or negative sequence impedance
• Simulate phase-to-ground, phase-phase, 3-phase, 2-phase-to-ground, and open phase faults.
• Simulate the effects of high fault resistance and arc resistance
• Visualize underreach and overreach effects by graphically comparing apparent to actual fault location to the apparent fault location measured by impedance elements.
• Verify element security to close up reverse faults or faults under abnormal or high load conditions.
• Evaluate the performance of distance or differential relaying to realistic CT saturation and CT transient characteristics
• Program multistage faults for more complex applications
• Import and directly use Doble SS1 files for testing
• Plus much, much more!! including all MTS-2150 features.
