Supervisory Based Robust Digital Control for Power Systems with UPFC and GPS Data Facilities

摘要

In this paper for a multi-machine power system equipped with Unified Power Flow Controller(UPFC), a robust digital supervisory control is designed. The main source of uncertainty considered during the design is one line circuit line opening of double circuit line. GPS data transmission facilities are used to synchronize the global data of the system to produce robust digital control input for the UPFC. To overcome heavy and uncertain load conditions a supervisory control scheme is proposed.
