Experimental verification of multi-input PSS with reactive power input fordamping low frequency power swing

A Multi-input Power System Stabilizer (MPSS) is developed to improve dampin g- of low frequency power swing in long distance power system and to emphas ize robustness for changing power system configuration and/or operating con ditions. In the MPSS, the deviation of reactive power Delta Q, changing rat es of terminal voltage and active power output are added to a Delta P + Del ta w input type PSS. In this paper, the AVR with the MPSS is applied to 100 [kVA] micro generator in CRIEPI's Power System Simulator and is compared w ith the Delta P + Delta w PSS. The MPSS is verified through linearized syst em analysis and experiment to damp low frequency power swing and to have be tter performance than the Delta P + Delta w PSS.
