OpenIPSL.Examples.TwoAreas

2 areas test system from Klein, Rogers, and Kundur

Information

This package contains a 11-bus 4-machine 2-area power grid model implemented in three different ways, generation unit models that are used in the network implementation and data packages for assisting initialization.

As mentioned previously, the user will find three test systems:

OpenIPSL.Examples.TwoAreas.Two_Areas_PSAT OpenIPSL.Examples.TwoAreas.Two_Areas_PSAT

11-bus 4-machine 2-area test system implemented with PSAT models

Information

This example is composed by the 11-bus 4-machine 2-area system, where these two areas are connected via weak tie lines. This test system is ideal for studying dynamic stability, power interchange, oscillation damping, etc.

The system undergoes a three-phase-to-ground fault on Bus 8 at 1s, lasting for 50ms. Simulate the system for 10 seconds. Variables of interest are the ones related to inter-area modes. For example:

which are variables that represent the generator's speed, in per unit. Note that generators 1 and 2 swing together, while swinging against generators 3 and 4. This is due to coherency between the area's group of generators.

OpenIPSL.Examples.TwoAreas.Two_Areas_PSSE OpenIPSL.Examples.TwoAreas.Two_Areas_PSSE

11-bus 4-machine 2-area test system implemented with machine models from PSSE

Information

This example is composed by the 11-bus 4-machine 2-area system, where these two areas are connected via weak tie lines. This test system is ideal for studying dynamic stability, power interchange, oscillation damping, etc.

The four generation units are composed only of machines, differently from the system Two_Areas_PSSE_AVR, where excitation systems are also represented.

The system undergoes a three-phase-to-ground fault on Bus 8 at 3s, lasting for 200ms. Simulate the system for 10 seconds. Variables of interest are the ones related to inter-area modes. For example:

which are variables that represent the generator's deviation from nominal speed, in per unit. Note that generators 1 and 2 swing together, while swinging against generators 3 and 4. This is due to coherency between the area's group of generators.

Compare these results with the ones from Two_Areas_PSSE_AVR.

OpenIPSL.Examples.TwoAreas.Two_Areas_PSSE_AVR OpenIPSL.Examples.TwoAreas.Two_Areas_PSSE_AVR

11-bus 4-machine 2-area test system implemented with machine and excitation system models from PSSE

Information

This example is composed by the 11-bus 4-machine 2-area system, where these two areas are connected via weak tie lines. This test system is ideal for studying dynamic stability, power interchange, oscillation damping, etc.

The four generation units are composed of machines and exciters, differently from the system Two_Areas_PSSE.

The system undergoes a three-phase-to-ground fault on Bus 8 at 3s, lasting for 200ms. Simulate the system for 10 seconds. Variables of interest are the ones related to inter-area modes. For example:
