Presentation Transcript

  1. Texas A&M University, Department of Electrical Engineering, College Station, Texas, USA Substation Data Integration & Information Exchange Student: Sasa Jakovljevic Advisor: Dr. Mladen Kezunovic Project objective: Utilize data obtained from Intelligent Electronic Devices (IEDs) to enhance Power System State Estimation

  2. Research Approach Concentrate on the following issues: • Analyze digital relays and other Intelligent Electronic Devices installed in substations • Explore modern trends in substation communications (IEC 61850) • Collect data from various locations within substation and adjust the format • Provide redundancy of measurements • Write an application for data processing and consistency checking • Communicate output to the higher level

  3. Substation Layout - One Line Representation Modeling Issues Power Apparatus: • Circuit Breakers • Disconnect Switches • Busbars • Load - Reactor Analog Measurements: • Currents [A] • Voltages [kV] • Power Flows [kW, kVAr] • Power Injections [same] Digital Measurements: • CB Statuses • DS Statuses • Ground Switches

  4. Three-phase Substation Model in SIMULINK

  5. Processing Algorithms in MATLAB Kirchoff’s Current Law Redundant Currents Branch Status Topology Checking

  6. Project Results - Future Work Output Tables Future Work: • Substation transition analysis • Switching sequences & interlocking • State tracking & predicting • Writing user friendly software Communicated Data: • Three-phase or single-phase output • Possible errors filtered out • More reliable data Node Table Branch Table
