I want to insert a braking resistor in a single machine infinite bus system to see the improvement in transient angle stability. As there is no specific model for braking resistor in PSS/E,can I use a load with circuit breaker for that braking resistor model?But I can not connect a circuit breaker then a load from one bus in PSS/E.Do I need to add one additional bus to connect the circuit breaker then from that bus to the load.

2.Anyone suggest the way to to connect/disconnect the braking resistor model in PSS/E manually.

3.Suppose for a system the pre fault condition is for 1s and then the fault is initiated ,how could I insert braking resistor considering activation time of 60ms . Do I need to go back to .sld/.sav file from perform simulation window and connect the circuit breaker and then run it at 1.06 sec ? I wonder if I can do that. Later the fault is cleared how do I disconnect the braking resistor in order to keep the generator synchronized . 4.If I model it like ,create a bus (bus type code-1)near the generator bus to connect the circuit breaker and then connect the restive load (For Braking resistor) and when I do the power flow keeping circuit breaker not in service first I got an error as here under Messages for api FNSL Topology error: 1 bus(es) with bus type code and series element status inconsistencies (000495). Could you please clarify the same how to proceed with this.

Any help? Thanks in advance
