Abstract

The processing of time delays is one of the key challenges in the use of wide-area power system stabilizer (WPSS) in engineering. In this study, the various time delays and their sources in WPSS applications are analyzed and measured. Strategies to reduce these time delays and the data transmission delay jitter of phasor measurement unit (PMU) used in WPSS closed-loop control are also investigated. A predictive control scheme that addresses the problems caused by time-varying delays in practical WPSS closed-loop applications is proposed. The effectiveness of the proposed scheme is verified through simulation experiments of Guizhou Power Grid (GZPG) in Southwestern China using a real time digital simulator. Moreover, this novel scheme has the potential to be improved and used widely in many applications.
