PS ERC Enhanced Reliability of Power System Operation (Kezunovic) Wireless communications Circuit breaker monitoring Gathering and processing substation data Using substation data for state estimation, fault location, switching sequences, etc. Comparing simulated data to the data recorded of in the field

PS ERC Automated Integration of Condition Monitoring ( McCalley) Integrate substation condition-based monitoring for transmission-level transformers and circuit breakers with system-wide RCM-based maintenance allocation and optimal scheduling system (developed in another PSerc- funded project) Use condition monitoring info in estimating equipment failure rates Relate maintenance tasks to failure rate reduction for circuit breakers Use multiagent system software design approach to integrate substation data

PS ERC Smart sensor development (Shoureshi) Development of an optical-based sensor for health assessment of high voltage oil-filled T&D equipment. Applications of light absorption spectroscopy in conditioning of transformer oil, thereby identifying potential causes of failures. Fuzzy-based pattern matching for predictive failure detection & identification.

PS ERC Detection, Prevention and Mitigation of Cascading Events (Vittal) Detection of major disturbances and protective relay operations leading to cascading events. Wide area measurement based remedial action. Adaptive islanding with selective underfrequency load shedding.

PS ERC Microgrid Protection and Control (Lasseter) Create a simulation test bed using the EMTP Investigate the effects of power electronic sources on short circuit currents in the Microgrid Develop and test protection and control strategies using the test bed simulator Implement protection systems on Wisconsin Electric Machines and Power Electronics Consortium’s hardware MicroGrida test bed

PS ERC Identification and Tracking of Parameters for Generator (Heydt) identify the transient and subtransient parameters of the field winding of a large synchronous generator from operating data develop a visual GUI-driven software package as a support tool. identify shorted field turns and incipient failures of the field of a large synchronous generator track selected parameters in time and with respect to operation.
