A Multi-input Power System Stabilizer (MPSS) was developed to improve damping of low frequency power swing in long distance power system and to expand robustness for changing power system configuration and/or operating condition.
In this paper, a setting scheme for the parameters of the MPSS is established. Moreover, the AVR with the MPSS is applied to a 100 [kVA] micro generator in CRIEPI's Power System Simulator and is compared with ΔP+Δω input type PSS. To verify the setting scheme of parameters and the power system stability improvement of the MPSS, a long distance fish bone type 4-machine infinite bus system is configured in the simulator, where complex swing modes exist with long period and poor damping.
The testing results show that the MPSS has good performance to damp low frequency power swing and to increase the power transfer limit in the power system with longer transmission line and large generator internal angle δ.
