Accurate Non-Divergent State Estimator (SE+ or SEPlus)

Accurate Non-Divergent State Estimator (SE+ or SEPlus) which has been recently developed at SEG is capable of providing a feasible voltage solution under any circumstances for power utility companies. SE+ is a state estimator which can avoid the crashes of system monitoring, and it has solved the divergence and robustness problem of state estimator which is open for more than 50 years.

 

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.

 

The PROMISES of SE+ or SEPlus:

1) Save the cost of engineers to manually fix the divergence problem of your state estimators.

2) No worries about reporting the divergence of your state estimators to NERC (a fine may be imposed if the divergence is severe).

3) No worries about the divergence of your post power flow analysis.

4) Increase the reliability of your EMS by 45%.

5) Largely improve the data quality (especially the reactive power and voltage magnitudes) in your daily operations.

6) Help detect the bad data which cause the divergence of your state estimator, and provide accurate true values of the contaminated measurements.

SE+ or SEPlus 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.

 

The Benefits of SE+ or SEPlus:

1) Capabling of providing a more accurate solution.

2) Capable of keeping your data clean and the calculations of the following functions like contingency analysis more accurate.

3) Capable of relieving your headache of reporting big failures (SE diverges) to NERC or even a penality.

4) Capable of providing more accurate real-time market prices

5) Capable of improving the security of your EMS by 45%.

6) Capable of making you to enjoy a continuous monitoring of system operations without interruptions.

7) Capable of removing the cost of your mannually tuning your SE when it diverges.

8) Capable of relieving your worry about the performance of your SE with SE+ as the backup plan.

9) Capable of helping you to identify bad data including topology errors in your model.
