Accurate Non-Divergent State Estimator (SE+)

SEG is proud to present the groundbreaking Accurate Non-Divergent State Estimator (SE+), a recent development that offers power utility companies a reliable and feasible voltage solution under any circumstances. With SE+, system monitoring crashes are avoided, addressing a long-standing challenge in the field. This state-of-the-art solution successfully resolves the historical issues of divergence and robustness that have persisted in state estimators for over 50 years. Experience the next level of power system stability and accuracy with SE+ from SEG.

SE+ serves as an ideal offline backup state estimator, specifically designed to enhance the robustness and data accuracy of power companies' daily operations. By integrating SE+ into their infrastructure, power companies can significantly improve the reliability of their systems and ensure accurate monitoring even in challenging circumstances. With SE+ as their backup solution, power companies can operate with confidence, knowing they have a dependable tool to maintain operational integrity and minimize potential disruptions.

SE+ offers a range of promising benefits:

  1. Cost savings: Eliminate the need for engineers to manually address state estimator divergence issues, reducing operational expenses.
  2. Compliance assurance: Avoid the risk of reporting state estimator divergence to NERC and potential fines associated with severe divergence cases.
  3. Reliable post power flow analysis: Bid farewell to concerns about divergence in post power flow analysis, ensuring accurate and dependable results.
  4. Enhanced EMS reliability: Boost the overall reliability of your Energy Management System (EMS) by up to 45%.
  5. Improved data quality: Experience significant improvements in data quality, particularly in reactive power and voltage magnitudes, leading to more precise daily operations.
  6. Bad data detection: Identify and flag problematic data that may cause state estimator divergence, providing accurate true values for contaminated measurements.

SE+ delivers these promises, empowering power companies with a robust and accurate state estimation solution, while mitigating operational challenges and ensuring compliance with industry regulations.

Comparison of Phisolophy

SE+ is more accurate than WLS based state estimator because SE+ is able to reject bad data

SE+ is an ideal offline backup state estimator for power companies who are willing to improve the levels of robustness and data accuracy of daily operations.
